Special thanks to Steve Chryssos of Twist Machine whose sponsorship allowed me to reach my goals and dreams.

Special Thanks to J. Ballenger and the good people of Powertrain Control Solutions whose customer service and technical expertise transformed my dreams into reality.

Great appreciation goes out to the folks at IPT Performance Transmissions who answered the plethora of questions I had for them. I look forward to doing business with them.

To make this project a reality you’ll need the following:

A car with an Automatic Transmission (RE4R01A in this case). Powertrain Control Solutions Universal Transmission Controller (PCS TCU). PCS Custom TCU wire harness plug and play solution. Twist Machine’s The Shrifter ™ paddle shifter. Aftermarket steering wheel and hub adapter (Grant signature GT wheel and 3560 adapter).

Other items you may need to have in order to complete the project:

Laptop or a desktop with the PCS TCU desktop programming kit USB to Serial adapter to connect your laptop to the TCU if it doesn’t have a serial port. Switch panel to mount your switches. Low or Mild budget build suggested in Automatic Transmission Ultimate Guide. Twist machine steering wheel adapter (Grant in my case). A bolt washer to space the hub adapter from the Shrifter ™ or a custom spacer from Twist Machine. PCS plug for the Shrifter™. Grant Steering wheel puller.

After you receive all your equipment, lay them out and make sure you have everything. There is nothing more frustrating than missing parts half-way thru an install. I apologize for the lack of pictures during the install. I will add more pics later.

Powertrain Control Solutions Universal Transmission Controller Install

Start by removing the interior panel and glove box in order to get to the TCU. If you have A/C, you’ll need to remove the fan blower assembly to get clear access to the TCU. This is a difficult task so take your time.



The TCU is located from the upper left side from the ECU. Remove the bolts holding down the TCU and remove the bolt holding the terminal harness. Attach the PCS wire harness to the OEM terminal and bolt it together. The PCS wire harness was made long so you can mount it elsewhere in the vehicle. Route the cable behind the glove box along side the firewall. Zip tie the cable so it stays in place.The wire harness comes with several other spare wires (some will be used later) and a serial cable to connect to your laptop. I mounted the PCS TCU behind the radio and ran the serial cable thru the center arm rest underneath the ashtray. This allows me to remove the ashtray and access the cable when I need to tune the TCU. This removable ashtray will serve me more than once.

Connect to your TCU and upload the latest software, firmware, and base calibration for your transmission. The folks at PCS were nice enough to post the download per my request for everyone’s use.

Software: v.2.0 http://www.powertraincontrolso...D.exe Firmware: 1.30.5 http://www.powertraincontrolso...6.TCU Firmware upgrade instructions: http://www.powertraincontrolso....html TCU Base Calibration: http://www.powertraincontrolso....html

After the downloads, make sure everything is correct. Double check the transmission set up, In my case I had to calibrate for the tire size, VLSD gear ratio, and shift logic. Drive around with your computer connected to the TCU and make sure everything its all gravy. You’ll know if its not!

Twist Machine Shrifter ™ Install



When you order the PCS TCU, make sure to let them know you’re installing the Shrifter™. They will include a plug to make the install easier.

Make sure your wheels are straight and the steering wheel is in the correct position.

Remove the OEM steering wheel. Pry the horn button off the wheel using a screwdriver. Use a steering wheel puller and remove the OEM wheel.



Install the aftermarket wheel hub as per instructions. Stop before you install the wheel, duh. (*Note: I placed a metal washer between the Grant hub and the Shrifter™. This was to add space between the Shrifter™ and shift column cover which was rubbing. If you do this you’ll need to get 3 longer bolts to connect to the hub.) Twist Machine makes custom spacers to provide proper clearances.

Place the Shrifter™ onto the hub and check for clearance. Install the steering wheel as per instruction and check for clearance. The paddles shouldn’t touch the signal arms and everything should move freely. Twist Machine can work with you to make any adjustments.



Now you’ll need to install the receive unit. Before you make any final mounting arrangements make sure the receiver is getting a clear signal from the Shrifter™. I installed the unit underneath the armrest. Connect the receiver to a switched 12volt and ground. Then run the plug that connects to the PCS TCU underneath the center console and attach it to the PCS TCU.



Install the provided switch in your desired location. This switch obviously turns on the manual mode. I mounted mine in the ashtray because I didn’t want anyone to see it (i.e. nosey mechanics). It also prevents it from being accidentally turned on.



Connect your laptop to the PCS TCU and make sure everything is correct. Make sure the TCU reads up shifts, down shifts, and on/off mode. PCS allows you to select between two manual modes: True manual, which requires you to control all gear changes or Smart manual, which will shift down to 1st after a complete stop.



Take a ride and see if you like it.

Driving Impressions

*Reminder! Driving impressions are mostly dependent on your TCU calibrations!

Daily Driving:

Driving automatics for so long almost made me forget how much I hated being in traffic with a manual. Spongy, sore knees, repetitive shifting, and general road rage are a thing of the past with the Shrifter™. With true manual mode you will be reminded of this inconvenience as it is necessary to downshift to 1st at every stoplight. In smart manual mode the TCU will downshift to 1st whenever the car comes to a complete stop requiring you to use the Shrifter™ for upshifts. But for every day use I recommend disabling the unit and allowing the transmission to function as normal.

Spirited Driving:

Windy country roads, highway on/off ramps, and open road courses are now your friend. Shift when you want and ride the redline through any situation. One of the main downfalls for the automatic transmissions is the fact that you cannot choose your gears unless using a floor mounted lever. Bang gears like never before!



Track:

The car moves and feels very similar to the M/T model 240sx; quick in and out of turns, excellent braking characteristics, snappy throttle response, and most importantly superb transmission control. A lot of this has to do with how the car is tuned but the Shrifter has certainly changed the car's attitude. Shifts are fast, accurate, and easy. Calibration B (true manual mode), was set for maximum line pressure and shift firmness. Downshifts are safe due to the configurations made available by the PCS TCU. For example, you can set the rev limiter for the transmission that way there is no risk of over-revving in the downshift. Also with engine brake reduced, the braking characteristics are greatly improved since the car no longer lunges forward with the downshift. The paddle shifter allowed me to remain in the optimal rpm range through out the turns which produced faster times on the track. With or without the Shrifter turned on, transmission temps never exceeded 210F. Oil temp always got to 250F (short sweep gauge). Water temp would be slightly above mid-level after 20 minutes. *These temperatures are not uncommon even though an oil cooler may be necessary in the future. Paddles never interfered with the operation of the vehicle. (i.e. hitting my hands, turn signals, etc.). Shift times are approximately 0.37-0.26 seconds. Basically, less than a half-second. Overall, the Shrifter and PCS TCU performed wonderfully and is a great addition to any A/T project car destined for the open track.



Drag:

Faster, firmer shifts. I can shift at the redline if I choose. The Shrifter may become very popular on drag240sx for this reason. http://www.drag240sx.com

Drift:

I'm not really interested in the drift sport that much so I haven't taken it out, yet. Beware to those drifters who flail their arms and hands all over the steering wheel trying to counter-steer.You will end up hitting your hands on the paddles so just let the steering wheel slide in your hands. The ability to maintain the engine within certain rpms will make drifting much easier for A/Ts.

Things to Consider:

As stated in my Automatic Transmissions Ultimate Guide, you must prepare the A/T for any high performance driving. I've noticed manual shifting will accelerate the heating of ATF without precaution. It is imperative to install a transmission temp gauge and cooler to combat this problem. Even with extended performance driving, the fluid in my car has never exceeded 180F because of the cooler (170-200 normal op. temp). Its very effective and cheap insurance. Keep both hands on the wheel. The paddles will interfere with your driving if you cant learn this. It has actually improved my form because my hands remain at the 10 and 3 while driving. Calibrate the TCU. Take the time to calibrate your transmission. The car may preform poorly if their is no time invested in tuning the car.

New Beginnings: We stand on the threshold of a new era of automotive transmissions control.

"How often does a genuinely new, exciting product come along? Before the Shrifter, paddle shifters could only be found on high-end exotic sports cars. Now, you can adapt that technology to your hot rod! Common on new vehicles, manumatic control provides manual shifting of an automatic transmission on demand. The driver gets the best of both worlds: Added control over rpm, plus full automatic convenience....."

"....With the Shrifter, power shifting your automatic has never been more safe, easier, or more exciting! Combined with a modern electronic transmission and controller, the Shrifter adds performance and style to your hot rod." (Steve Chryssos, Twist Machine)

Wow... I was actually thinking about this while I was showering yesterday... I am glad that somebody came up with something.

Very nice very nice.

[sil8tdrftr]

wow!!!

that is sooo cool....what kind of racing do you do with that... time attack? or is that just how you like to drive?

[PantherRacer]

Reason #1 to stay automatic: Traffic.Reason #2 to stay automatic: Paddle shifter.Reason #3 to stay automatic: Faster (now we can REALLY say that!).Reason #4 to stay automatic: Sleeper.REason #5 to stay automatic: Eat/drink (non-alcoholic beverages) & drive. YESSSSSS

[sereneDelusions]

I wish my auto ka-t had this....awesome writeup. Also, thanks for all the in depth info your giving about auto trannys. Im definately watching this topic.

[Repo Man]

I think we'll turn this into an article. Very nice.

[Onizuka]

Awww, I was hoping for a hydraulic actuator mounted to a manual transmission when I read the title (Like F1/racing/exotic cars have). Still freakin cool though

[AmoebAssassin]

Would've liked to see an e-clutched mechanically actuated manual gearbox, but thats pretty cool too.

[Repo Man]

Bunch of damned jaded basturds.

[let5l1de]

Nice conversion and great post!

Paddle shifter. = $$

e-clutched mechanically actuated manual gearbox. = $$$$$ (someone needs to step up )

[le_ryan]

SWeet, too rich for mah blood though.Yeah thanx for all the info on the auto transmission.!

[whiterps13]

How hard does it shift? Can you chirp the tires or does it ease the throttle like on other autos?

Pretty cool write-up.

[CarShowz]

wow.......good ****, thats Great!!:D

[PantherRacer]

How hard does it shift? Can you chirp the tires or does it ease the throttle like on other autos?

I wanna know too

[S14tat]

eating and drinking while drivin..... YES!!! that is a very very sick swap and i love the paddles that you used.

[frsh13]

Thats crazy...looks like a clean install. Thats the kind of thing that could get you into magazines n stuff

[Lormegil]

REAL men learn to eat/drink while driving a stick

REAL men learn to eat/drink while driving a stick

you get used to it after a while, but it does suck to have a burger on your right hand then steering with your left hand and then when u shift u have to throw your right hand to shift with the burger in your hand then a piece of tomatoe or pickle or mayo falls in the car or clothes... but i still do it.

anyways thats awesome man, i wish i could get that for my car! now you can go race in formula 1 races! yes! j/k

I've learned to drink a good part of my soda before I sit it in my lap... theres been to many times when I've come back from lunch break with a wet spot on my junk from where soda spilled out trying to shift.

[moyea]

This car will be on the tracks in Northern California's Speedways via NASA HPDE/TT (2006-07).

It will attend as many events as possible this year as I believe I may be going to Iraq soon.

My car is not built for show, just amature race. The car has too many flaws, rust, and cracks in the dash to be in a mag. Although, maybe somebody will feature it in Grassroots Motorsports. Lets hope! If anyone is thinking of using the Shrifter for show, that would be an excellent idea. The Shrifter comes in a mirror finish or brushed aluminum and is very easy to paint.

Pretty cool write-up.

The shifting attributes is controlled by the aftermarket PCS TCU, not the Shrifter. In time the driveline is disengaged from the engine there is possibilty of traction loss. There is a slip parameter that can be adjusted which may cause the wheels to behave in such a manner. This defeats the point of the upgrade. Its not a toy and takes a serious investment to reach its full potential.

SWeet, too rich for mah blood though.Yeah thanx for all the info on the auto transmission.!

The cost is about the same as the M/T swap. Now, A/Ters have two alternatives to transmission "swaps". Also, more demand for this conversion will reduce manufacture cost which will translate savings to the buyer.

That is very possible and has been done before with Nissan 300ZX. I forget the guys name but it should be on the internet as one of the fastest Zs. Now making it clutchless or e-clutch, would take some serious effort. Either way, the Shrifter might have the possibility of controllin such a transmission set-up.

I think we'll turn this into an article. Very nice.

I would like that very much. I would like to add more pics down the line though.

Amazing work man, just amazing.

[nvrplzd240]

dude this is pretty sweet

[NoTcHbAcK240sx]

props to you! looks pretty sweet

[SilviaSlydSydway]

I kinda wish i had an A/T

[jamied311]

nuff said!

[Danzors]

Hmm I think it's pretty cool except like he stated, couldn't really drift with it could ya? But that all depends on what you're using your car for

[SilviaSlydSydway]

Can We get a video???

[TOPSECRT88]

IMO this is the best article on NICO. A++++++, great job.

I wanted to get rid of my auto and was going to be going 5spd before i saw this. Now, that has changed...i am seriously considering this concept. I guess you'd be able to call my car a "show car" once its done, so i think this will finish off the car very nicely.

EDIT: is there still 3 gears correct? 1,2, and D w/ the new paddle shifter?

#1: Only women are allowed to complain about this. I drive in traffic everyday. It's not bothersome at all.

The other numbers:

First of all, it's NOT as quick as a manual transmission 240sx. The 240sx automatic transmission CANNOT shift as fast as a decent driver can.

In addition, without the use of the clutch, there are so many driving techniques that you cannot take advantage of.

It is definately a cool project, but not really very practical or cost effective. Simply using a manual transmission will be better in every way, except that now you have to use so much more effort to use your left foot (sarcasm).

There are even complaints about FERRARI paddle shifter gearboxes not being as good as the manual versions. It is hard to get it right, and nearly all enthusiasts will still choose the third pedal.

I view this the same way I view stuff like tein's edfc. It's a cool novelty, but nothing more. Not very purposeful.

Disclaimer: I have respect for the thread creator. This is something that has never been done before, and although I don't like it, it is still very well executed.
