Technical issues and repair guidelines

One of the main peculiarities of this transmission in comparison with common automatic gearboxes lies in the electronic control. This gearbox uses 5 solenoids together with the transmission control module and its sensors to control shift timing, shift feel, and give on board diagnostics.


Repair specialists say that the valve body is the most problematic component in TAAT. Delays, slippages, kicks or lack of Reverse during gear-shifting are likely to be caused by valve body issues. However, there are several other sources of a Reverse problem:

1. Delay or no Reverse may be caused by the loose-fitting main shaft nut

2. Malfunctioning car speed sensor may also lead to no-Reverse condition.

3. Wrong adjustment of the pattern select switch
