Yeah, I was never fond of the 1-2 shift. Barton helped a bit, skip shift eliminator helped a bit and removing the CDV helped a bit. The only thing that really worked for me was to almost pull it out of first, engage the clutch and slide into second. It’s done much faster but pulling it out of gear as the throttle is pulled back and almost using the clutch to engage the next gear. This experience cured me from ever really looking at another manual and going auto instead, especially with a powerful engine.Not sure about the Hellcats, but my '21 RT has a very noticeable notchy feel when shifting 1-2. Not sure if it'll improve with more kms.
There was a class action suit against Ford last year on the MT82 and MT82 D-4 but has been partly dismissed.The crappy shifting isn't a Dodge issue. This is an issue in the Camero and the Mustang as well. They all used the same transmission. I called Tremec and found that the issue is in the synchros and they have a kit that can be installed to cure this but the cost is on us, the owners. None of the manufactures considered this worthy of a recall and none would did anything about it.
the shifter layout is different for the C6 Vette - Challengers have the remote shifter - external of the transmission case vs. the top mount internal shifter. Vipers also used a different case with a top mount shifter layout, and similarly Mustangs (Shelby) did this as well. There's many variants on the TR6060, depending on the application and chassis its going intoI believe my 2008 zo6 had a tremec and it shifted MUCH better then my challenger or the other 6 speed challengers i drove. Ive drove a couple other zo6s and never thought to myself "this thing doesnt shift well" hands down better then my srt even with the hurst shifter
