While accelerating while passing my truck suddenly felt like it went into neutral and the check engine light came on. I slowed down to and was able to drive at approx 35-40mph with out any problems. I hooked it up to a scanner and got a code P0700 (transmission control system malfunction) and codes P0735, P0734 & P0733 (5th 4th and 3rd gear ratio incorrect). I'm almost convinced its the relay module but not sure.
