They are the same.
Any 4L60E transmission, 1993 and up. The mechanical 4L60 and 700R4 from 1992 and earlier will not work.
It'll fit, but it won't work - the 4L60E is an electronically controlled transmission, whereas the 4L60 (itself simply a rebadged 700R4) is a mechanically controlled transmission. 1992 was the last year mechanical transmissions were used in these vehicles.
A 4L60 (NOT a 4L60E) from a 2WD pickup will work. It MIGHT be possible that you'll need to use the original bell housing from the Caprice, although I can't for sure that this is the case.
Yes it will fit, but it won't work... The 89 computer is not programed to the 4L60E transmission, Therefore the transmission will not shift are even work.
A 2WD 4L60E from 96 will work for a 94 application, yes.
The 89 does not have a 4L60E. The 4L60E wasn't used until 1993. The predecessor to the 4L60E was the mechanically controlled 4L60, which itself was just a rebadged 700R4. It will not be compatible with a 97 model year vehicle.
NO. the computer and the wireing harness is different. 3/4 tons MUST have the 4L80E and the 1/2 tons MUST have the 4L60E
4L60-E OR 4L-80E DEPENDING ON THE SIZE OF TRUCK 4L60E HAS 16 PAN BOLTS 4L80E HAS 17 PAN BOLTS NEW ANSWER: If it is a 1/2 ton then it MUST have a 1996 or 1997 4L60E put in it. NO OTHER YEARS WILL WORK. If it is a 3/4 ton then it MUST have the 4L80E put in it and NO other years will work.
That would be the 4L60E transmission and that is the ONLY ONE THAT WILL WORK.
If that 700R4 was attached to a mechanical engine (or even a TBI engine, which only had basic electronic functions), it's not going to work... there's no engine ECM for that transmission ECM on the 4L60E to interface with.
4L60E transmission and that is the ONLY 1 that will work.
The ONLY 1 that will work in it is the 4L60E transmission.
