Yes the transmission will work provided both are the same 2wd or 4wd. Can't put a 2wd in a 4wd or vice versa. Converting one to the other would require a complete disassembly of both transmission. In which case just taking one apart and rebuilding it would be less work. They also both have to be from a 4.3L because the engine to transmission bolt pattern on the bell housing is different on a 2.2L.

is there any difference between a 4l60e that came out of a 1500 4wd VS one that came out of a 4wd s10 with a 4.3? would it put too much on the little 4.3?

also, is the difference between the 4wd and the 2wd 4l60e trans the gearing? or the output shaft? and I guess the same with the 2.2...I know it has a different bell housing but that could be swapped on these trans right? is the gearing different on those as well? or are they all the same gearing?

Well, the 2.2l 4l60e never had a 4wd version and is internally much weaker, in addition to the gearing differences.

I aggree with the no 4x4 option with a 4 cyl engine, but there is no internal gearing differences in the 4L60E family of transmissions. See the 4L60Evs4L65Evs4L70E sticky at the top of this section. I can promise that all 4L60E series transmission got internal gear ratio's of. I attached a page from the GM 4L60E technician guide.
1st 3.059
2nd 1.625
3rd 1.000
4th 0.696
Rev 2.294
the 2.2L usually got a 4.10 rear end for the lack of torque (max torque 145)/HP 120 max.
Internal differences for the 2.2L are:
It only got 5) 3-4 frictions, a larger 1-2 servo (#554) and only a .420 boost valve. they also came with a 2700 stall converter.
The V-6/V-8 trans got 6)3-4 frictions the std 553 srevo and a .470 boost valve. the V- got a 2000 stall & the V-8 got a 1400-1600 stall
To answer the OP question yes S10 V-6 transmission's are interchangeable 1996-2004.

Hmm, just assumed because the manual 2.2l trucks also have 3.73/4.10 gearing but first gear is 3.94 on the NV1500.

You can swap the 98 only 4L60E 4wd trans into an S-series. 99 up full size has a bunch of differences which make using it very difficult.

also, is the difference between the 4wd and the 2wd 4l60e trans the gearing? or the output shaft?
Both the output shaft and the tail housing on a 4wd are different than a 2wd. The output shaft is removed toward the front of the case. It's the last part to come out of the case. If you're going to tear a 4L60e down that far why take apart 2 of them. Just rebuild the first one. It'll be completely disassembled.

and I guess the same with the 2.2...I know it has a different bell housing but that could be swapped on these trans right? is the gearing different on those as well? or are they all the same gearing?
Answered above. The 2.2L 4l60e is not assembled to handle the torque of a V6. The 3-4 frictions are already the weak link in a 4l60e. Running a lighter duty assembly is asking for failure. And again if you take it apart far enough to change that, just rebuild the one you have.

Man, your knowledge & wisdom on S10 & Blazer transmissions is much appreciated, thank you.

Thank you! 4L60E's is pretty much all I build now and has been since 2010...
