hey men, i just performed the tranny solenoid and governor press. sensor swap. that took care of the "hunting for second gear", but just before this fix my tranny was starting to shift out of second at 2500 rpm. this problem is still here. if i drive it real easy, it will shift normal, but regular driving seems to mesh first and second together with a high shift to third. any clue? '06 mega 4x4 33" tires, 3.73, bully dog on 75 hp, 5" flo pro exhaust, 52 K on truck. thanks.

 

How did you fix your high shifting problem? I'm having the same issue now on my 2006 48RE, i get DTC P1755. I've already changed the solenoid, sensor, VB wiring, ttv motor and adjusted the bands but the 2500rpm shift problem is still here. I would really appreciate if you could tell me what was your culprit.
