Replace transmission in 2002 GMC Yukon...

[Ataim]

Has anyone ever done one? if so how hard is it and is any special tools necessary?

Now I know what GM meant when they said "like a rock".

Seriously on my 99, it always ended up being a trip to the shop, to fine tune that GM feeling. Wish I could help.

Yes. I've done quite a few GM truck transmission changes. I assume it is 2WD and automatic. You'll need tools to release the quick-connect trans cooler lines (you can borrow 'em if you need). I'd recommend long extensions with swivel sockets (15mm) made of "impact" grade steel. Motivated workers can get by with less specialized tools, though.

Why stop with just the transmission replace the entire thing with a Sequoia.

That is why GM needs to go bankrupt so that Toyota can start making the Yukon in Detroit!

This job is MUCH easier with a transmission jack. I have the Harbor Freight transmission attachment for floor jacks with remoeable cradles i fyou need a loner. Its easy to use and very heavy-duty. Doesn't hurt to have an engine hoist to support the motor either. You'll have a big crossmember to unbolt at the rear of the tranny, so make sure youve got the right tool for that. Probably a large bolt, but GM puts TORX stuff in some strange places.

Have you already sourced a tranny? Seems like most places would do the install for not much more than the cost of the tranny, as its pretty simple and they get to keep the core.

I also have a 2002 Yukon. How many miles did you get out of the transmission? What was the specific failure? Just curious.

Mine has been retired to weekend hauler and truck duty only. I bought a more sensible daily driver.
