I got 5th and 6th gear ratio incorrect codes, just under 10k miles on trans and I only felt it slip a little 2 times. Pulled pan fluid was clean and smelled fine no clutch material in pan. Pulled VB apart installed revmax separator plate. Got new tuning from NRE. Did a quick learn. Was in 6th gear going up a hill about 5 miles after quick learn with cruise set about 55mph and it slipped right before it down shifted. Before pulling trans apart check CVIs on all drums, everything was well within spec. Any ideas before a trans tear down to actually look at my OD clutches and rebuild it again? I was not the one who rebuilt it the first time.
