1744 - Excessive slip detected during full TCC (Torque Convertor Clutch)engagement

Tony, this means that either your TC is not locking up or the that when it does lock, it is slipping. See, inside your torque convertor, there is a clutch. This clutch is used to lock the two different sections of the torque convertor.

Your current problem lye's within the Torque Convertor. The actually root cause of your problem lies within the valve body. Within the valve body, there's pistons that move forward and back. These pistons control the fluid flow throughout the valve body and the rest of the transmission. The piston that controls the fluid going to your TC is seezeing up inside the bore of the valve body, most likely due to a combination of dirt, grit, poor maintaince (not changing fluid often as needed), so on and so on. You stated that you just bought the car, so no... I'm not blaming you.

To make it short, you might could get away with just replacing the valve body and torque convertor. If this has been a problem that has gone on for a long while, then you will most likely require a rebuild.

Reason I state that you might need a rebuild, is because when the problem that you currently have states to happen, the line pressure of the transmission will run out of control. this in turn can cause damage to some of the other hard parts inside, like the forward/direct drum and such.

If you would like more information on this and many other topics, you can check out my CD4E web page.. We currently have another member in the process of rebuilding his tranmission here, with plenty of pictures.

If you have any other questions, please feel free to ask. And again, welcome aboard!

If all this seems over whelming to ya, don't worry. Just calm down and we will work through it together. I might have a few other suggestions for ya, depending if you are open to them. No golden arch or anything, but they helped me anyway.
