I have a 99 Taurus with an AX4N and I am getting P1742 and P1744 codes. The car will act like it has a manual transmission when cold, so the torque converter is lock on. I need to replace the TCC solenoid as I was quoted $600 to replace it at a tranny shop.

I need to know where the TCC solenoid is. I have a pic courtesy of powertoolman's post on fixing a tranny, but I am not too sure if one of these solenoids are the TCC.

Is the TCC solenoid one of the "Analog Solenoids" in the pic?



Thanks,
Ian

Here's a drawing showing the location. Be sure to get one that has the proper coil resistance. '96-'97 are different than the '98-'99. Also be sure to check the wire loom. The connector that is sticking straight up out of the tranny under the intake hose may be corroded too.

If the solenoid or associated valve is on, the TCC will be on and it will stall when put in gear.

Think: manual trans, dump clutch at idle.

FYI the TCC fails engaged. It needs fluid pressure to release.

I was wondering the same thing myself. I don't think that the TCC solenoid is easily accessed. The next time I change the oil in my mom's car, I am gonna take a close look. Her car sputters/idles weird when you first put it into drive or reverse...like the torque converter doesn't know what to do.

The sputter when going into gear is likely a sticking IAC, a vac leak, or other easy to fix problem. VERY unlikely it is a trans problem.

TCC can be changed by removing the tranny side cover. Can be done at home with hand tools. The hard part is getting the cover off. Lowering the driver side subframe some helps.

Jeff K, Can the fron trans cover be removed without lowering the subframe? I want to do some more chekout before I try replacing anything in the trans, but I would like to know for future reference. Thanks.
