ZF 8HP70 Transmission
New to the forum. Hoping to gain some insight from folks.
I have a 2016 Challenger R/T. Bought it new in 2017. Almost right off the bat, the transmission would down shift very harshly when I decelerated, mostly from 2 to 1, and often from 3 to 2 as well. Like, it was so harsh that the car would lurch and passengers were confused. Could feel the "clunk" of the gear shift. I took it to a dealer, and over the course of 4 or 5 visits and 2-3 months, they went through their protocol (update TCM, reprogram TCM, replace valve body, and finally replace transmission). Well, guess what, it's still exhibiting the same problems. I took it back, and opened a STAR case with Dodge, who sent a regional technician out, and he came back with "it's behaving normally."
I've just lived with it for the last couple of months since that, but I'm curious if anyone else has this issue with the transmission on this model? Appreciate any of your thoughts. If there's already an open thread on this, I must've missed it. Please let me know if there's one and I'll head over there!
