Frank - Are these 4L60E differences the same for the V6 F-Bodies?

Yes, they are. The only real difference between the V-6 and the V-8 4l60Es are the cases. The servos differed from model to model also, The v-6 F-Body 4L60Es used the 553 servo, whereas F-Bodies, Vettes, and B-Bodies used the "corvette" servo. Only the 4 cylinder S-10s used the 554 servo. 1993 V-8 truck units also came with the "Corvette" servo. Other than the servos, the internals are identical, unlike older 700R4 units, which had less clutches in the 6 cylinder models. The 90 degree V-6 4L60Es had the same bellhousing as the V-8.

Quick truck 4l60e question @Cahall
We discussed my 95 k2500 the other day and you told me 95 was a stand alone year due to the 3-2 downshift I believe. That being said what would it take to make other year 60e or even 80e trans to work in my 95? Is it just a tune or is there more to it? Thanks again!96 Trans Am LT1 A4......2 broken rods

Technically you can't even swap to a '96 computer to control a 'later 4l60E because the '96 LT1 uses a crank sensor. The differences in the transmission are the valve body casting, 3-2 solenoid, seperator plate, and internal wiring harness. As for the 4L80E, I can't accurately answer that because we don't do those swaps. We had too many customers with the cars slowing down too much years ago. From what I understand, any year 4L60E computer can be made to operate a 4L80E though. An '80E doesn't use a 3-2 solenoid.

I have been reading about the differences between the 4L60E years.
I have a 96 Impala SS. I bought it in '98 with 30,000 miles. I've had the trans rebuilt twice. The second time it seemed to pulse at high rpm going into third. The trans shop swapped the convertor and flywheel but it seemed the same. I had a 95 Impala SS motor and trans and he swapped the other '95 trans in and it still seemed the same so we left it there. After about 50,000 miles I have never noticed an issue. We put the rebuilt trans behind the 95 engine and it seems to be okay too with a 95 PCM.
Now I have a trans and harness from a L99 94 Caprice. It is hooked to an LT1 and computor from a '95 Vette. It is destined for a swap into my 78 Malibu. Does this look like trouble? Malibu & LT1.JPGCan the 94 L99 PCM be reprogrammed for the LT1? There is a 95 Caprice in the local U Pick yard with a L99. I can get the trans for $200. Is that the necessary approoach?
Pete
