Hello all im having issues with my 1975 CF with the 237 in it. I can only get my RPMS up to 2100 and its just not quite enough to get the truck to shift properly. If i use the hand throttle in the cab i can get the RPMS up high enough for it the shift right thru all its gears no problem. It has the 4 speed allison auto. Ive tried to adjust linkage, check the air actuator at the motor is throwing full throw with the pedal full depressed. I'm just not getting the linkage on the passenger side to fully turn the injection pump to get all my RPMS out of it. Any help would be greatly appreciated.
