Ok,
This might be a long one, so strap in.
I have a 2019 silverado with the MQE transmission (8L90e). I am close to 30k miles and want to at least do a pan drop and filter change. I contacted Holley/B&M and I will be their person to verify that the transmission pan will work on the new trucks.
This is my issue, my truck was built in January 2019, there was an update to the transmission fluid in late 2019, I have contacted my local dealer, my buddy that works in the parts department said that the fluid is backwards compatible, i then talked to a service adviser (dont know this person) they said that the fluid is NOT backwards compatible and if I only do the 6-8 quarts it can void my warranty, I would have to do the flush. I never had any issues with a shutter on my truck and do not want to make the wrong call. I seem some people do the flush that doesnt fix a problem and they have to swap the transmission out but they were having problems going into the dealer anyways.
Can (hopefully someone that works for GM) let me know if I would be fine with just doing a pan drop/filter?
