Re: FLASH: TRANSMISSION SHIFT ENHANCEMENTS (vehicles with 3.6L engine)
Just got back from getting the latest DTCM flash....all I can say is wow. Thing is great now...no more whiplash on 2-1, 2-3, and 3-4 shifts and i don't have that sudden thump/jolt when getting back on the gas after coasting. I actually pulled my fuse a week or two ago so I think I got most of the garbage data out of the system already. We'll see what I think after I put some more miles on it but so far, well worth the time and effort of getting the update. Like most others have said, I can tell it's not completely perfect...80% I'd say. However, my fear is that it's close enough that they won't do any more refinement on the software as there's no real "problem" anymore. Time will tell.
So, when i called to make my appt, the dealer didn't have the RRT in their system and tried to tell me it didn't apply to my vehicle but I told them I was bringing it in to get the HVAC flash anyways. I know the service advisor and tech on a first name basis now (not sure if that's a good thing or not) so the tech asked me if i wanted to learn a few things, hopped in the Jeep and took me in the shop to show me the flash process. I think they actually wanted to prove to me that these magical flash updates didn't apply to my vehicle. Plugged in, pulled up the software, and surely there was the DTCM, PCM, and HVAC updates available for install - no TCM update. I was a little surprised that this latest revision is just the DTCM update and there was not a secondary TCM update after getting the TCM flashed in August. Maybe that part was mentioned here previously and I just didn't pick up on it.
