Hi folks,

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!

Thanks!

Just out of curiosity, did you keep taking it to the same dealer? I would look into taking it to another dealer for another evaluation, if possible.

There's quite a few variables that could cause that to happen, but quite likely it has nothing to do with the transmission but could be a sensor getting a faulty input commanding a higher than normal line pressure to the transmission. A line pressure gauge and scan tool would be a good place to start. Dealers these days just check TSB and fire the parts cannon. Like the guy said contact another dealer.

There is no idiot light on the dashboard - so it *must* be "operating normally".... <sigh>.

I can't stand it when you take a car to a dealership and you get the "no problem found" line when you know *damn* well that something isn't right - especially when a dealershop tech rides with you and even they can "feel" the issue as well. But - no light on the dash = no real problem to them... I swear, most "mechanics" these days don't know how to troubleshoot a problem unless there is a light on the dashboard to tell them what's wrong.

I get it, cars are very complex nowadays, but you still need to be able to troubleshoot issues even when the computer doesn't tell you whats wrong.

I had the similar issues mostly in bumper to bumper traffic. They told me that it's normal but then they replaced the rear because it was making a grinding noise when turning at slow speeds and now the clunk is about 98% gone. It does it but it's hardly noticeable. The service rep came from Ford and she said that they were having similar issues with the 10 speed transmission. I googled it and sure enough it's out there.

I've wondered how the 8 speed auto trans compares to the 5 speed. My 2012 5 speed is a pretty smooth shifting trans.

I don't know if the ZF 8 speed trans is made in the U.S. or not. I was at the auto show maybe two years ago and the people at the Dodge table told me that the ZF trans for the Challenger was made in U.S. under license.

Chrysler is making its version of the ZF transmissions (845RE), and most of the parts for them, in Indiana, and ZF is also building them in Greenville, South Carolina.

the A8 is an awesome unit! I drive it like it's meant to be driven, in track mode manually paddled up and down, I have a few really cool twisty hilly back roads out in corn fields so the cat can stretch her claws

What's ZF stand for? They are a German company? I was looking at Audi's a few years ago and I thought they used ZF trans also.

My HC did that a lot in sport and track mode. Maybe try pulling the fuses or the battery for 10 min or so and let it reset all the adaptives in the ECU, Trans and BCM and see if it changes. I did that with my HC and it smoothed out a good bit but eventually came back if I drove aggressively. Admittedly difficult for anyone (here) to help diagnose without driving it since everyone has a different idea of "hard shift" etc etc. Def go with a 2nd opinion from another dealer
