Update.. I was curious and installed the TCU from the limited into the SRT6 and I do not get a gear ratio error code anymore. I wonder if a TCU from a Limited will do the trick?
But.... regardless of TCU modules I'm getting a P2562 "The gear is implausible or the transmission is slipping" Transmission acting very odd, sometimes works ok and sometimes completely pissed off. I dropped the trans pan, checked filter and pan for debris. looked clean.. I captured about 4 1/2 quarts of fluid, normal I think. Put it all back for time being till I figure out whats up..

So I'm thinking its one of the three. Transmission was damaged in the accident, perhaps conductor plate issues or gear shifter malfunctions....unless someone has other thoughts.
