Hi I swapped out my transmission and differentials from another truck. The ratio on the original trany & diferentals was 3.9 I replaced with 2.93
It messed my speedometer by ~17mph i took it to local volvo dealer and the ajusted some parameter and now shows right mph!
For some reason thou, truck speed governs out at 64mph
Dealer raised speed governor to 85mph and it still governs out at 64mph
Patrick said something bout (speed being limited by gear ratio)
Anyone know what's going on?
