Is this normal

[Enjun]

I have a 2019 Limited (non-e-toque) and updated the exhaust, now that I can hear the exhaust, I've noticed when the truck down shifts it seems to rev match is this normal, I did not hear anything with stock exhaust. Is this normal or is this a sign of transmission problems, only have 18k.

Normal, you can only really hear it with a aftermarket muffler/exhaust and love the way that ZF8 downshifts and sounds like it's rev-matching those downshifts. Obviously not in the traditional sense as in with a clutch and blipping the throttle, but the ZF8 does have a mechanical way to rev-match the downshifts, I believe there is literature on certain Dodge Cars with the ZF8 that mentions rev-match downshifting.

Considering BMW has dropped their own 7-speed DCT on their M-cars for the ZF8, it pretty reinforces how great this line of transmissions are. It's party due to packaging but also the better overall shifting feel at lower speeds while still being fast and capable.

Yeah, normal. I sorta wish mine would let engine speed fall a little lower when decelerating, but on the other hand it's a truck and they programmed it to have torque readily available.

ZF8 might go down as one of the greatest 1500 transmissions....after 3 years, I still have a hard time feeling it shift.
