C30 transmission issues

Post by jmtreport » Fri Jan 11, 2019 7:14 pm

Hi new here. I have a 2008 c30 automatic with 184000 miles on it. I am getting a hard shift between 2nd and 3rd gear. I am aware of the b4 servo update and awaiting its arrive. Anything else I should do? Further more. If I replace the transmission, I should only have to take it to volvo to do the programming correct?

If you do replace the transmission, use the TCM (Transmission Control Module) that is in the car now. You should not need any reprogramming.
