Could not find anything recently on this, sorry if I missed it.

Decided to change (some of) my fluid and filter on my 8 speed (it had the new fluid and flush at 2000 miles as a pre-emptive strike) now at 50,000 miles, but with S/C and a lot of towing near max GCWR and at high speed/high temp figured it could not hurt to change out the fluid and filter (not a flush).

At any rate, I can't get the trans pan to clear the crossover exhaust pipe to remove it, it comes very close but jams up. The service manual does not mention anything about dropping the exhaust crossover, so wonder what y'all who have done this encountered. Going to tackle it again in the morning.

Thanks

Pan won’t come out without dropping exhaust. I just reached in with a rag and cleaned it out really good and reassembled it. I’ve done it 3 times since I’ve had mine. About to do it again at 85000

Thanks for that. One thing is the filter looks different than the one I got from GM, mainly the inlet pipe. If I look at "fitment" it shows that it fits the 2019 as in the video, but sure looks different. Guess I will find out tomorrow.

That's a filter for a Sierra/Silverado, not a Canyon/Colorado. Always enter your VIN when ordering parts.

Interesting I guess their application chart is messed up then. Good call on the VIN

And when you search for a 2017 Sierra 1500 5.3 filter you get the same filter as shown for the Colorado. I guess we will find out when he tries to install it tomorrow.

There's a youtube that pulled the pan out by prying on the exhaust. You only need 1/2 in.

I'm wondering if a guy undid the exhaust brackets and supports at the back of trans. Maybe lift the back of trans and possibly have the clearance needed to pull the pan out.

So here is the correct filter (quite a few online applications or "fitments" are incorrect). Just picked up at local GMC dealer ~$33 including tax.
The box shows the GM # as well as the AC Delco part number.

Some references show a newer GM part number 24295812, but then the same ACD number.

Don't need to drop the crossover much to provide clearance. Be careful not to force the pan at all as the interference/closest item is a solenoid connector, then also the internal multipin connector.

It is easy to pull the pipe down. When I reassembled it, I put anti seize on the studs to make it easier next time. With the pipe down, it is very easy to r& r the filter. I plan on doing it every other year. I installed new gaskets for the cross over also. Just in case.
Put an asterisk on that! *It is easy to pull the pipe down when relatively new. 5 years+ in the rust belt and those studs on the cat are snapping if they come out at all. One of the youtube vids for a fluid change on these trucks (not the one posted here) he had to cut off the nuts and put new studs in.

question:
Is it a big deal to just remove the exhaust crossover since you have it loose anyway?

How about the pan gasket? A lot of transmission pan gaskets are the reusable design. Those who have did this, new pan gasket or re use old one?

Genuine GM Filter is dirt cheap at Rock Auto. $13 bucks and change but w/o the gasket.

Looks like that filter you referenced is for the 6 speed transmission.

Look at Rock Auto for a '21 model and the list three Genuine GM filters. 6 speed, 8 speed and 10 speed transmissions. For the Silverado, which will be the same part (6 and 8 speed parts) for the twins.

I actually had the kit from NAPA, probably equivalent quality parts but the shrink overwrap was open on the outlet tube and there was contamination in it, as well as the cardboard being bent and a kink in the gasket. Needless to say got a refund. In the case of NAPA not much different than GM dealer pricewise. The pan gasket is reusable and good quality, I guess you could reuse the filter gasket.

So as a side note on fluid capacity, the pan drop and filter change yielded 7.5 quarts so that is how much I put back in. I had a flush and new fluid back about 48,000 miles ago not long after I bought the truck, so what was in there is from that procedure. Seems like other folks who have done the filter change are less than 7.5 quarts. I will be doing a level check later.
