Re: Transmission problems

I'm at 400 miles and the shifting has gotten so much better over the last 80 miles.
The last 80 miles has been all stop and go, city. I do think that has helped a lot.
So I do hope it keeps getting better.

Re: Transmission problems

Im at 1700 now. Upshifting from 1-2 and 2-3 still feels like im getting rear ended. Downshifting into 5 and 1 are bad too. Everything else is smooth. Gonna go to the dealer after the new year

I can't seem to update my own comment for some reason, but I wanted to mention that in 9th gear the 3.2 liter V-6 was running 1600 RPMs at 80 MPH.

Re: Transmission problems

I'm up to about 450 miles on my Cherokee Sport and the shifting has gotten considerably smoother. It was hard from 1-2 and 2-3, especially at a slow acceleration at first. The more miles I put on it the better it is getting.
