Looking for advice on doing a pan drop and filter replacement on my 2012 Silverado 2500hd with the 6.0 gas and 6l90e transmission. My main question is does the exhaust pipe need to be lowered to completely remove the pan? The only videos I see on the net are half ton silverados where the exhaust pipe needs to be lowered. On my 2500hd the exhaust pipe does indeed run below the pan, but it appears to have enough clearance to work it off, but I know looks can be deceiving.

Anybody here ever done this to a similar model year truck to give advice?

Thanks!

Just did it 3 months ago in my 2017, plenty of room. It is a 45,000 mile service transmission. A complete flush is about 12.5 quarts. A pan drop and fill is about 6.
I did a pan drop, filter and fill and drove it 500 miles, drained it from the drain plug and filled it. It is nice and clean.

Next I will disconnect a cooler line and do fluid transfer. I am at 33,000 miles.
