I had the same problem. It means there is crud stuck in the valve body, causing the TCC solenoids to get stuck on or off. P0741 means TCC is stuck off, P0742 means TCC is stuck on.

P0742 is the worse of the two because it probably means your trans is bucking as it downshifts, trying to deal with the torque demand of staying locked in overdrive. It may stall even. This could damage your trans if left unchecked, and in my case, the problem did not work itself out. It was really stuck.

My transmission mechanic had to replace the valvebody to fix this problem. I think he dropped the unit to do it, but I've heard you can swap (or at least access) the valvebody on some cars without removing the entire transaxle.

If you know someone with a Tech II, there may be a way to energize the TCC solenoid, maybe get it unstuck. I've heard of this being done, but it was not done to my car, and I do not know the procedure for doing it correctly. Good luck, feel free to read through my experience here:

If you can replace the clutch solenoids, or at least move them on & off, that might fix the problem. Best of luck!
