Depends on the year but yes, except for the fact that it does not have the right tailshaft, meaning you would need to swap yours over because of the torque arm mount.

And honestly, don't expect an answer in 15 mins.

Yes, but you have to put your tailshaft on it.

Thank you sir

Yes it will work just fine. But let me make one clarification.... The part referred to as a "tailshaft" is actually the part we call the extension housing. The output shaft is commonly referred to as a tailshaft. No biggie, just don't want to have folks coming away confused.

The extension housing is held to the main case with 6 bolts. It does not have any sealant on it. The way it seals to the main body of the case is with a large square cut o-ring. Just make sure that the o-ring is seated fully against the main case when you swap your old tailhousing on and you'll be fine.

What year & engine is this truck? There were several versions of the 4L60 transmission and they do not all interchange.

Stated above, year 2000. The shift linkage bracket may need to come off the f-body trans as well.

Or you can buy a torque arm relocation trans bracket and leave the trans alone.

Sorry mod, my bad, I missed the Y2K note above.

I just wanna confirm here guys. Some trucks, even in model year 2000, had small block 350 engines. The transmission is different.

So, LS1TA, did the donor truck have a LS engine?

No passenger trucks did. They converted over in 97/98. Only thing I can think of that might still have the Vortec 5.7 is an Express van.

The transmission is from a 02 tahoe 2wd 5.3 vortech....
where can I buy this torque arm relocation bracket ? Do I need it?

Cool. The transmission and torque should bolt right up. Some truck LS engines had slightly longer crankshafts so I'd have a look into that first. The difference is made up in the flexplate.

UMI makes nice chassis and suspension goodies, they fit well and they are good to deal with if there's a problem. Choose what you need then get pricing from the LS1tech sponsors, they help keep this place alive.

The old body style Tahoe was still around in 2000 with the 5.7, not a lot built but they're out there. The NBS Tahoe came out in 2000, not 99' like the trucks.

Are the harness connectors that go connected to the trans same?

Paul Bell

iTrader: (9)

Yes they should be.

Trucks got it first, SUVs got it the following year. The SUVs I remember had a split year where you could get either with the same year designation during the transition.

Our moderator was right about the Express/Savana vans. They retained the small block/big block configuration through 2002. In 2003 they got a big body/chassis/drivetrain update which included the LS series replacing all gas V8 engines.
