It's not just the 8 spd having problems
WARNING: A couple of days ago my jeeps transmission got a computer flash at the dealer. The paper work says reprogram module, powertrain control (pcm)
30203 flashed pcm per tsb 18-027-13. 68170423AB to current part number 68170423AD. (0- low skilled). Since this update my transmission has been shifting hard and at low speed about 3 to 5 mph I get this deep knock noise that sounds like it's coming from under the passenger seat. Can't drive in sand / mud mode without major driveline binding. And I swear it's slipping a little bit. Al this started after the dealer worked on it , whatever that program / flash was it has ruining or already has ruined my tranny. At this point I'm scared to take it back every time they work on it, it's either not fixed or something else has a problem. One things for sure everything wrong with my jeep is the fault of Chryslers mechanics. Not sure that my wk2 would make it another day at there shop and it's the only shop within 60 miles of me. Anyway maybe those with the 8 spd tranny need a software update scary huh.
