WTK: What RPM is my Truck Tranny Supposed to Shift Gears??? M923A2

[beltfed1934]

All,

My truck is a 2010 Texarkana rebuild, it runs great, but the transmission doesnt shift until the rpms are nearly at 2000, is this correct? Most gears, it shifts at between 1900 and 2000 rpm. Also, I nearly have the pedal to the floor to get the 2000rpm, is this correct, I nearly have to stand on the pedal.

TIA,
Austin

Its not a regular passenger vehicle, so yes its fine. Floor the throttle and then let off whenever you arrive at your desired cruising speed.

The Allison spec is for the transmission to shift at 300 rpm below governed rpm for all gears but the highest. This shift is supposed to be 500 below governed rpm.

You can cause the transmission to short shift by not applying full throttle.

You can also hold the gear by manually shifting.

The correct way to drive a Allison is to bring the rpm up to 200 below governed and let the trans do the shifting.
