Transmission trouble I have a 2.2L s10 with the 4L60E trans. At 70mph It unlocks the torque converter and after about 40 minutes it downshifts to 3rd for no reason. The moter is running great, for a 2.2, that is. Is the tranny getting a bad signal from the motor? Is this a valve body problem? Is the tcc lockup solinoid part of the issue?
