I know this thread is a little old, but I have a 97 service manual for a 4T60E and 4T65E if you'd like any info.

Any info on which cars the different chain ratios were present in, for the 4T60-E? Looks like all had the same gears, but there were 3 different factory chain ratios (35/35, 37/33, 33/37).

=====EDIT======
I missed a chain ratio there. Those 3 are for the 4t65-e, and the 4t60-e. But the 4t60-e has one additional, 28/27.

I'm aware of what vehicles the 4T60-E is avail in.

I do not know though, which chain ratio was used in each of those vehicles. This is what my question was.
