Just Starting to learn how to tune.

Currently have a 2013 Ram 2500 Longhorn at my transmission shop. It is already egr deleted and tuned. I have rebuilt the transmission and have been doing the relearn test drive. The 3-4 Shift is late and has a double bump @ 38-40 miles per hour. I have pulled the file and have noticed what looks to be some higher numbers and not at all smooth for the 3-4 shift scheduling, and the 3-4 ramp Rate of acceleration, when compared to the other shifts. Other trucks with the same drivetrain drive and shift smooth, however I have not been able to compare files. I am nervous about pulling these files since I locked up my own truck.

Looking for some feed back or clarification, or even a stock file to compare too. Thank you

I can look later this evening and even share a stock file for comparison

Definitely need to be careful on read attempts on already tuned trucks, doesn’t take much to get the ecm stuck in rom boot

Thank you, I would greatly appreciate that.

Not a damn clue what was going on in there but made a pile of changes for you. Man there was shit in there changed for shifts that don't even occur at all in the 68RFE. I'm not certain if there are deeper changes in there that was made, would take me some time to look. But give the attached file a try.

Once again, Thank you! I hope this helps.

It should make a noticeable difference.

IT DID!!! It drives and shifts so much smoother now. Thank You.
