Hay guys im looking for some insight here, Just finished up a truck and its having an issue. I have a V2. Tuned ECM with one of PPEI's tunes (eco_tow 30HP). Runs great, but cust. was pulling a 40' float and trans set a P0732- 2nd gear incorrect ratio. Talked to tuner and he wanted me to clear code and complete Fastlearn. Sent Cust. out with trailer and problem hasn't returned. Tuners rep suggested this was internal trans, however I don't feel this is the case (26,00 miles and not doing this until now). No less I was wondering if anyone had seem any issues like this. Hoping it just needs to learn adapts.....

BTW I have ZERO exp writing tunes, Im wet and green behind the ears here. So im likely to ask some stupid questions.
