Hey guys,
I have a 2014 Ram 1500 5.7V8 with the 8 speed (3.92 rear). I have been running HF 89/91 octane rev B tune for a couple of weeks now (ran 91_race tune before that for over a month but shifts were too harsh for a daily driver) and I am starting to get a shudder in the transmission when it shifts from 2-3 and 3-4 under light acceleration. If I get after it then I don't feel the shudder but this is my daily driver and live in the city so can't get after it a lot without getting a ticket.....
I just reverted the truck back to stock and don't feel the shudder since the torque management is not altered like the HF tunes. I was told this was normal when torque management was reduced but I also don't want to screw up my transmission!
I have a service appointment schedules for this next Monday to get the transmission looked over and also check for updates to the software. The truck has always shifted slow from 2-3 than any other gear which drives me nuts! I am hoping there is a software update that will fix this.
Any help is much appreciated!!
