Well they did not make this an easily serviceable transmission.. gotta remove the mid pipe tomorrow.. damn it.

did the brake fluid tonight, it was dark green! Also did the rear diff. that wasn't too bad. no real shavings, all the teeth seemed to be intact.

When i used to do my '01 it was a pia to get out but it came down without removing exhaust, the only thong i remember being a ***** was the trans shift cable and bracket, if I remember right. I think i bent it a little and then bent it back to shape after i bolted bracket back on....maybe they changed something tho....

When I got my 03 Yukon, I had to change both shift solenoids in the transmission. I didn't have to remove the exhaust for that. I did unbolt the shift linkage though. After that the pan came off, just needed to come off at an angle.

Oh, and speaking of the shift solenoids, they are around $10 each. Might be worth throwing in a new pair if you are dropping the pan anyway.

Just like galante i bent the shift cable bracket down a little so i could slide the pan out. I tried to get the bracket bolts out but they`re torx bolts and you can`t see them. I couldn`t get them to move so i bent the bracket and never bent it back because the bend did not affect the way it shifts.

Right on guys. I tried bending a little, didn't seem like it wanted to move. maybe I'll set my purse down and try that again. those exhaust bolts look like a pain!

How about try from the other end of the exhaust, is there a way to lower the hangers a little to give you clearance?

I'll take a look, but I think I'm going to revoke the linkage bracket. I just watched a you tube on it. it was like midnight when I was dicking with it. fresh eyes might help with the 2 hidden Tora bolts.

I was also watching a vid about doing an entire flush using the rad line. and pumping 4qt a time out into a bucket, then refilling 4x. not sure I'll do that. just a few changes of the atf, and call it good. what do you guys think?

The radiator flush is a really good method. There is a super write up stickied over on GMFS. Here's the thing, you don't have to drop the pan to do it, and you can change as much or as little of the fluid as you want if you're worried about causing problems. If you just pump out the first 3-4 qts, and refill, you've essentially just drained the pan and added some fresh fluid.

When i bent mine i just put a large adjustable wrench on the bracket and pulled down. I tried pliers at first but as you found out that it`s pretty thick steel.

well damn, I already have a new pan to put on. I'll be changing the pan, and filter. I'll look into the write ups, it would be nice to know is it's all new fluid in there.

how does pulling down do anything, wouldn't it have to be bent to the side to get the clearance?

Does your new pan have a drain plug, and is it the deep one? It's not a bad thing to do a new filter, seal, and gasket. Also don't forget that all new fluid isn't necessarily a good thing if it's got high mileage and never been serviced (I think it's safe to assume on this vehicle). Maybe just drain the pan and refresh at each of your next few oil changes, or even every other time. Just thinking out loud here.

The hardest part I had dropping my pan was the stupid drain plug. Man that thing was in there. The two torx bolts aren't hard to get to for the shift linkage brackets. Plus disconnect the cable itself from the transmission. Takes five quarts of fluid if all you do is drop the pan. I'd reccomend a new filter also.

yeah man I got a whole new shabang. I like the idea of being done today, and not waiting on fittings. since I'll be changing the oil in short intervals for awhile, the trans will have all new fluid pretty quickly.

And yeah, no one has loved this car, ever. I brought it back to life as far as I'm concerned. Some might call me a hero, but who's to say.

That's a nice pan! How much more extra capacity? Expensive? Looks really good.
