Hello I been stumped with this problem on my F150 Im trying to sell it but want to get this problem fixed 1st.
When cold the transmission shifts fine through all gears and even applies tcc. But say I drive it from San Jose To S.F. It will be fine. But after that if I dont let it cool down at least 2 hours thats when the problem shows up.
problem: When at Normal Operating Tempurature and having been driven a while. The transmission will slip in and out of 4th to OD. If I depress the AP at any cruising speed it will cycle in and out of OD. Untill I ease off the AP.
DTC: p0741 Torque Converter Clutch System stuck off
DTC: p1744 TCC System Perform.
I have replaced The TCC Solenoid and its still doing it but with no codes.
Im trying to fix this problem as cheap as possible so I can sell it.
Understanding you have drained, flushed and replaced the filter, whats left. Disconnect the battery and reconnect after 15 minutes. Run the re-learn sequences and see if it works. You put in new parts. If it doesn't, figure on a torque converter replacement/ tranny reman.
