Any time I run my Griffin CS in mode 1 (tow safe) my shift points are noticeably very firm, maybe a little too firm. When pulling a hill sometimes I get a very noticeable “CLUNK” when it shifts into overdrive. I am wondering if anyone else has experienced this with an Edge or Griffin programmer in the tow mode.
I’m running what I think is a stock original 4R100. I bought the truck at auction with 180K on it and it now has 220K. Samples sent to Blackstone all indicate normal wear levels in the tranny.
