Short story is, I had a TCM failure during my tune. I replaced and programmed the TCM. Ever since, the trans seems to slip starting around 25mph thru 45mph. Seems to be third and fourth gear, causing me to have to pull throttle in order to get it to shift. My tuner isn't seeing any issues on the engine side, so I'm afraid might have a mechanical failure in the trans. Any help would be appreciated.
Gen V trans slippage?

I will make one calibration change for an additional $100 per change. For example, changing a shift point for a given gear is $100 vs changing a shift point and a pressure setting would be $200. That value can be used towards the full custom tuning price.
