i have a 1996 chevy silverado C1500 2WD with 5.7 vortec. The tranny I found for sale is for a 1996 Chevy silverado C1500 2WD 5.0 vortec. is the tranny that was bolted to the 5.0 the same as the 5.7 I have????

Since no one has answered so far, I will take a GUESS. I don't know these trucks nor these years, so it is a GUESS:
Since both engines are LT style engines, the trans will be a 298mm 4L60E. You should therefore be able to swap in a 4L60E from any other '96 vehicle, any other '97 vehicle, and perhaps some '95 vehicles. Also many '98 and '99 vehicles that have an LT engine and not an LS engine. (Vehicles that have a 4L60E of course).
You cannot use a '94 4L60E though.
Again, just my best guess. Hopefully someone will confirm or correct me.

thank you so much. I have been researching for the last week or so and learned there are so many variations of the 4l60e. And something new last ight was when I go looking up exact transmissions for my truck now I am seeing there is a difference in extended cabs and short cabs trannys!..lol..Now I am going crazy. The only thing I can see being different there is the drive shaft length , not the transmission, but who knows. I hope someone can give specifics that' done swaps like this for 2wd full size C1500 trucks.

He needs a '96 or later trans. The 1995 uses a different 3-2 control solenoid internally that is 10-15 OHMS whereas the '96 and later 60E (all of them) use a 20-25 OHM 3-2 control solenoid. Also the wiring harness on the '95 internally is different due to the different 3-2 solenoid.

He has a 1 piece case unit as well so by '98 the 1 piece units were pretty scarce. The 3 piece units were used as early as '96 in the S-10's and became pretty much standard on all trucks by mid to late '98 with some V8 equipped trucks having them in early '98, and all V6's having had them by this time.

This post is a few days old and he has probably figured this out by now.

Thanks for the additional info.
It seems when I specify a '96+ trans someone claims that some end-of-model '95 have the newer VB. In the future I will ignore those 1% outliers, assuming they even exist.

As long as a '98+ is the LT-style 298mm input shaft, it won't matter if its a 1 piece or 3 piece case. However a LS-style 300mm input shaft, which are all 3 piece and with a bolt hole in the 12 O'Clock position, will not bolt up to a LT engine.

MrVedit,
Please note that even though the 298MM units use the same pump, input drum, and torque converter there are still differences between the 1 & 3 piece case that prevent them from interchanging with each other. Specifically the cooler lines come in at a different angle, the filler tube comes in at a different angle. So, they can be made to interchange with each other, but it will take a little bid of fiddling with bending the lines, and either finding the correct filler tube, or heating and bending the original, to get it to work. Better just to stay with the same type of unit as was removed.

Also, you CAN bolt a late LS style (99 +) trans to an earlier engine without problem if you can get the bolt holes for the flywheel to converter figured out. I have had several vehicles come into my shop that people have done this on. Some just hog out the holes in the flywheel, and others take the time to remove the flywheel and properly drill them.

You must also be cautious when it comes to the 4.3L V6 engines as they carried on the B-29 style-298MM shaft all the way through 2004.

Thank you for the detailed info about the differences between the 1-piece and 3-piece cases. I will remember that for future posts.
I knew the 4.3L V6 used the 298mm version well past '98 and now I know exactly how long.
I hope you find the time to keep posting here and sharing your extensive knowledge.
