2010 Denali XL AWD right? Try and work the 6L80 AWD trans service into the stuff below. When the trans is out labor cost are cut 50-90%. There’s routine maint items like:
* replacement of the oil pan gasket
* rear main seal
* 99¢ oil pump O ring
* oil press sensor
* 2 front diff mounts (4 bushes)
* motor mounts
* exh gaskets (optional ARP stud upgrade time).
* Torque converter + service
* 1/2 GM trans cable fix kit
Buy your OEM parts @ R/A and places like parts geek. Save 50-75%. Have an Indi do the job.
On the horizon, for the the long run, research rebuild / upgrade options if the AFM goes south and for the front suspension. Stuff like cylinder head upgrades when AFM dies and / or almost $0 cost to swap to aluminum front suspension components.
I really didn't want to believe it, I thought there had to be some bad luck involved with it. but nope, all this like clock work on every one of them.
