Can anyone offer advice on what my problem might be? Two weeks ago I got the following codes:
P0743 Torque converter clutch solenoid circuit electrical
P0740 Torque converter lockup malfunction
P0443 Evaporative emission control system purge control valve
I took it to a transmission place, and they found it was not the solenoid, but as it was the original (2002 Sport) replaced it. That seems to have solved the P0740 problem. He said the 743 was solved too, due to a wire that was shorted out behind the fuse box (behind glove compartment). Well, the 743 came back. I did not ask him to deal with the 443 code.
Oh, and at the same time, the AC didn't work. He said the fix he did fixed the AC, too.
Took it back and he swapped around a couple of relays and found they were all "ok". Also, said that by doing so, it fixed it. He supposedly drove it around quite a bit and the code did not show and the AC was working.
Well, I picked it up and after 5 miles, the 743 code came back (as did the 443). And, they won't clear.
Anyone ever have this problem, or ideas before I take it to the dealer?
