2 wheel ver. 4X4
I'm looking for a new to me, used 7004r transmission for my "87" S10 Blazer. One thing I've noticed in want ad's is people stipulating 2 wheel and 4X4. With the exception of a tranfer case on a 4X4 is there a difference? Sorry I'm a newbie to drive train work. Motors and electrical I can handle. Drive trains I'm lost.
Thanks

Yes, there is a difference. A 2wd transmission has a longer output shaft that extends out into a tail housing. A 4wd trans will have a shorter output shaft that couples up to the front of the transfer case instead of going through the tail housing.
The output shaft can be swapped to turn a 2wd transmission into a 4wd transmission or vice versa. Now here's the rub... The transmission must be gutted to make the swap. The output shaft comes out through the front of the transmission.

Crap, how hard is it to "gut" a trany. Sounds like I might just as well rebuild the one I have. Bring's me to my next question. How hard is it to rebuild a transmission? I've worked engine's and electrical, never a transmission.

If you have never rebuilt a modern automatic transmission, I would not recommend trying it.

anytime i get a used transmission i have it rebuilt anyways before i put it in. i did bring a transmission in before to have a output shaft swapped before and it cost $100. but that was on a 1977 th350. might be a little more on the newer trans, and again if your gonna go through all that mess might as well just rebuild the thing while its all torn apart
