Hey guys, I have a really quick question.
My daughter's 2019 GMC Canyon with the 8L45 transmission recently had trans failure. I found an 8L45 out of a 2021 GMC Canyon I can get. My question to you folks is, is the transmission interchangeable since the TCM is external?
Please excuse my inexperience with the 8l45 as I am mostly familiar with the V8 GM transmission interchangeability.
Thank you in advance!
