I purchased a trans from a 91Q w/140k off e-bay for $200picked it up in Conn. 5 hours round trip in a massive rain storm 2 friday ago.Dropped it at my friends transmission shop, for full re-buildhe installed a shift kit from a combo of 2 vehicles (pathfinder and isuzu rodeo) said the springs were 2x stiffer.he filed down the paddles and added an extra clutch to each gear,cross hatched the clutches for better grabbingturned up the pressure on the solenoid (think 1/4 turn)waiting for the torque convertor to come back from re-builder who was increasing stall rate to somewhere between 2500-2800.filling w/dextron III full synthetic.

How much will this cost you?

it is a friend thus he is hooking me up i think around 1,200 - 1,500 plus the $200 i paid for my core. I will let u know when i know

Find out how many your friend is willing to do. I am interested.

very cool James. smart move to go after the wide ratio 1st and 2nd of the early boxes. one thing you want to be sure to mention to your friend [if he's not already doin it], is to increse the lube to the planetary. the early units had a lot of problems with this.there is an aftermarket kit for this, i can hook you up if your friend is not familiar. also, if you don't have a honkin cooler--no better time to get one.

personally, i'm hoping to execute some other tweaks and not have to plunk down on a rebuild for a while. but when i do, it would be to go for the early gear set as you are. let us know how it turns out and if your friend wants to do more!

Jeff Williams: Layla is a perfect candidate for the line pressure solenoid experiment. hit me an address, and I'll send you a 10 watt 68 ohm to put in and see what happens. based on your previous descriptions--i bet it would be like a whole new trans to you--no charge.

i am sure he will do as many as asked lets see how it does firsti will find out pricing when he puts it in my car, waiting until wife is in Hong Kong so i have a car to drive ,and a little less grief (replacing a good trans) next couple of weeks

GQ:i just called him and he did increase lube to planetary, made me feel like i asked him a stupid question. when we met thru a mutual friend (my mechanic) i was told he does excellent thorough work. the first time i was at his shop there was a 1970 dodge challenger 340 6pack plumb purple in mint condition that he just finished the tranny on. (one of my favorite cars ever).I will certainly update once installed.He suggested i keep my old trans just in case , it works almost perfect, and has 30k on the solenoid pack.

GQ:I understand the first geat is about 12% quicker 58 tooth compared to 52 tooth i think; Is the 2nd gear different as well?

cant u turn up the pressure from the solenoid pack when u do a trans service??

Jeff- It's in the outgoing post. hopefully our beloved mail service won't mistake it for a letter bomb...Wes put a pict in the vb thread showing location. I think Layla is no TCS, so should be a breeze.

James- don't know about 'turning up' the line pressure solenoid. perhaps there is a different plunger depth--i was unaware that they are adjustable.glad to hear he is taking care of business, don't know why he felt it necessary to make YOU feel stupid.

70 challengers are hot! the only MoPar on my top 10 musclecar list.

He was just like of course i increased lube to planetary - as if everyone knows to do that.

1/4 turn on the adjustment screw on pressure solenoid bumps it up

i love all muscle cars and have owned a few and have the privelege to drive a few of my friends - bur IMHO Mopar rules

Let us know how it goes. Interesting tidbit about the line pressure solenoid having an adjustment.

I wonder if there are any shops around us (Socal) that know the Jatco trans secrets. It's also used in 300zx TT, Subaru SVX, Isuzu NPR box trucks and some others.

Oh, I just found out that the 300zxtt torque converter is a higher stall than the stock Q converter. Might be too high though - 3000 rpm with the 300zx, although the VG turbo has more torque at that point than the VH45. Maybe 2800 or so with the VH?

I'll see if I can find what RPM the pathy converter stalls at...

Don't forget to increase cooler size - a loose converter creates a LOT more heat than the tight stock converter.

Funny, I'm a mopar guy too - I've had a couple of early A-bodies. My favorite was a 64 Dart with 360. I swapped in a four-speed rather than rebuild the 904, but Mopar automatics are tough and easy to modify.

I just wish the Jatco trans was as well documented.

hmm, that could be decent.. have a 3000 stall OEM converter, i like that idea!

Better than these cheap retarted rebuilt ones.... OEM or billet, IMHO..

does the tt convertor spin on ??i have a b&m cooler. Is that what u r refering to ??

jamesmost wrote:does the tt convertor spin on ??

In THEORY it does. But as I've not done it I can't say for sure. Both transmissions have the same input shaft splines so the stator should be the same. A transmission shop friend said it should, but he hasn't tried it either.

Quote »i have a b&m cooler. Is that what u r refering to ??[/quote]Yes, just make sure you have the biggest you can fit. Loose converters heat the fluid up more than tight ones.

Another item of automatic hotness:

The 300z torque convertor fit perfectly into my transmission my guy said it is a 2600 stall. Going into the car on the 29th this month
