The torque converter clutch seems to be engaging in reverse. The transmission works fine in Drive. After replacing ALL of the fluid, 15.5 qts, and the filter, the problem still exists. Has anyone run into this problem before.
Which trans do you have - the E4OD or the AOD? With 15.5 qts fluid, I suspect E4OD. If so, you may be looking at a bad solenoid pack. It can be checked externally for electrical problems. You will ned the ATSG manual for it to get all the correct values. You may also have a related fault code stored in the ECM if you scan it. Keep in mind that many transmission problem like this are related to engine problems.
