It's my tow rig, and I'm hoping somebody will school me on automatics..

02 expedition, throwing a TCC electrical code. No torque converter lockup. 4R100 transmission.

Guessin a TCC solenoid?

Anybody have a good resource to go to for transmission novices such as myself? I'd love to fix it myself, but I'm not experienced.

If it's throwing a electrical code then it could be a wiring problem or it could be the solenoid.

The solenoid pack will be about $250 and is easy to change. It's pull the pan and remove a dozen bolts and it'll come off and then slide the new one in and you're golden. it's on the same complication level as changing the trans filter.

What is the actual number code that is getting thrown?

P0743, and I've unplugged and replugged the electrical connectors on the transmission. I'd just like to be sure it's the solenoid before I go down the path of replacing parts -- but $250's not bad for a learning experience.
