I can dig that. Once you have the pan off you will see if building it may be your only option.

But yeah, I would at least try the kit.

Actually I found a 95 4L60E on our local craigslist with a converter and aluminum drive shaft out of a pickup for $150. He claims its good with high mileage. I may buy it just for a core to build. I have a 4L80 shaft with the good 1350 ujoints that I scored but the two yokes for the 4L60 and 10 bolt will cost me $100. I am hoping the pick up truck drive shaft is the same length as my van.

I do see where the 93/94 separator plate is one part # from Transgo and the 95 is a different #. Does anybody know if the 95 model is better or worse?

the separator plates are different because the lock-up strategy was changed to PWM in 1995.

I feel like a rookie here PWM ?

Is that torque management ? If it is could I use the 93 valve body in the 95 unit ? I have heard nothing but bad things about torque management. I do have to do a burnout once a year at our clubs truck in.

PS: If my van didn't look and run so good, I would buy something from this century. However I don't think they build em like they used to.

No they don't build them like they used to, they build them better.

Many shops in my area have been slow this summer, I think they build them better now.

PWM is an acronym for pulse width modulation. Instead of an on off solenoid application, PWM allows for a partial application of components, such as torque converter clutchs. Maybe a, too simplistic explanation.

Your computer may not like the 95 valve body.

But I'm not too bg on switching stuff around anyway.

You don't want to stick with what you have? You said it drove and upshifted good, just a shudder in reverse, correct?

torque management is the system that cuts power of the engine and pressure inside the trans during a high torque load upshift,

I have scanned a few vehicle systems with software from EASE diagnostic using a laptop computer. i did this during various levels of torque load on the vehicle.

The PCM will cut the engine timing advance back to zero at a high load upshift ( WOT). I saw this on a 2000 Silverado 5.3 2wd truck (mine).

I'll add to briscoe comments.... with the PWM systems of lockup there are new materials on the converter clutch to with stand the slippage of the lockup clutch.

ok I got it. Fluid is directed just like fuel thru an injector via PWM what will they thing of next.

I do want to keep my trans. I a paraplegic and use a wheel chair. I have hand controls and a lift in the van. I am interested in the 95 box for a usable unit while I build mine. I don't want any downtime.

I am a big believer of repairing what you have. That way you always know what you have.
