Was going through the GT motorsport website and ran across this.

Now I know I don't have the skill to tackle this but would this be cheaper then sending your stock one to stillen or another shop usually located in cali and have to wait a week to drive your car.

Its pretty easy to install the transgo kits!

you'll have faster shifts for sure.

I had a transgo shift reprogrammer kit on the Hemi!

Basically drop the pan.Remove the filter (replace it)Remove 100 little 8mm zerk head screws (put them in magnetic pan)Put valve body on clean work surface.remove valve body pressure plateremove valves one at a time and replace the seals and springs with the transgo parts.discard the old pressure plate install the new transgo pressure plate.Reinstall valve body using 100 8mm zerk head screwsInstall NEW transmission filtercoat transmission pan with 1 tube of black RTV wait about 30 min for it to become tacky.reinstall transmission pan don't torque down all the way just finger tight.wait about 2 hours and tighten to specs.wait 24 hours and refill transmission fluid

This is a good time to install and upgrade torque convertor or different transmission pan?

That's really similar to what Stillen would be using. There is a lot more to it than "bolting in" a kit, but yeah, if you know your stuff, it's a cheap option. Labor is the insane part. There is some grinding of the ports as well I do believe. Screw that up, and the transmission is done.

If you had a Hemi Ram this is what you'd be working with



And if you decided to do the torque convertor too

I did a TransGo shift improver kit on my 97 firebird formula. Wasn't too hard, it just made me nervous with the small check balls and springs. The car was an animal after!! Going from Park to Drive was instantaneous instead of the 1 second delay. Shifts were much crisper...the car was 10x better.

Not sure if the G35 will be similar...but it was one of my better mods for the 'Bird.

The shift reprogrammer kit is the 2nd step shift improver is the 1st step.

Everything in the improver kit comes in the reprogrammer kit + a few extras

You should put the transgo kit in and write a review so you can get your custom title!!

Since you have the pan/valvebody off the transmission anyway you are about 10 bolts away from pulling the transmission. Why not find a nice 2800-3000 rpm stall convertor and swap that in. My stock Hemi torque convertor was 1100 rpm stall and 1.9 torque multiplication. The aftermarket Suncoast converter was 2800 stall, 3000 flash stall and 2.54:1 torque multiplication! WOW your money spends easy!

See THIS is why I can't start modifing the G.... there is no stopping point.

The stock converter has to be around 2,200-2,500 stall.

Its really easy to find out.

Put one foot firmly on the brake and one foot gently on the gas. The point where the power starts to make it to the back tires is the stall point.

I have never heard of a stock converter stalling above 1500 rpm.

If your torque converter is breaking it will stall higher... for about 1000 miles
