Default 2000 4.3L S-10 4L60e Trans to 95 LT1...?

I have a rolling chassis 95 LT1 car that is in near perfect shape. I had to sell the engine and 6 speed last year due to not having a job. Now I have found a 95 LT1 engine with 80,000 miles for $800 at a local yard. I also have 2 perfectly good 4L60e's from 2 different 2000' S-trucks. One has been rebuilt with some stronger parts. I plan to get a 3800 V6 car's tailshaft and put it on the S-10 trans. My question is...will the transmissions electrical sensors hook up to the 95 automatic harness that I will be buying from the junkyard? How about the controlling of the transmission...can this be tuned into the ECM? I am having PCM for less do a tune for my 3.42 rear end gears and 3500 TCI stall. The car will also get a 218/224 solid roller Xtreme energy cam with Comp OEM style short travel hyd. lifters and full Comp valve train. Yes I know I just said hyd lifters on a solid roller cam...its a mild enough cam that it will be just fine. Thanks for any help with this subject.

They are both 4L60e's. I have figured out that the newer trans is a 6 bolt tail housing so I guess I will just need a torque arm relocation bracket. I just dont know what to do about making the ecm work and the speedometer still work. Is this something that can be tuned into it? Thanks

It can be tuned if needed...... make sure the pattern of the bell housing is the same as well

If s10 was 4x4 it wont work. 4x4 uses a different case to bolt up the transfer case.

2 wheel and 4 wheel drive transmissions are the same the only difference is the rear outputshaft ,the v6 tran should bolt right up,the only thing is the newer 4l60e trans have a fully inclosed bellhousing but the main 6 bolts should line right up.Besides that the only other thing I would do is make sure the flywheel backspacing is the same
