Technical issues and repair guidelines
The main repair problems are related to the auxiliary power take-off equipment, torque dividers, and the main one – the cooling process or heat exchanger. Designers of these transmissions quite consciously reduced the transmission resource by means of cooling.
There are 3 main problems related to valve bodies of Allison 1000/2000/2400:
1. Sticking E-shift. When the valve sticks TCM detects that the pressure sensor doesn’t change the status and sets the trouble code P0872- after that the gearbox switches to the failsafe mode.
2. F-trim valve sleeve. The inside diameter of the sleeve wears out, leading to the torque converter clutch surge and trouble code P0741 – indicating the torque converter clutch slipping. . When lock-up stops operating and the P0741 code sets, the torque converter can overheat the ATF, causing damage to the torque converter and rapid deterioration of the ATF.
3. Warped castings. Valve bodies for these transmissions do not have separator plate gaskets, therefore it is required that two halves of the valve body should be flat sanded for protection from cross leakages. In this case locating pins should be removed to flat sand the valve body.
