I keep getting this p0741 code (TCC switch stuck in off position) The converter does not lock up sometimes and every once in a while it will. I bought this converter used and have put about 25000 hard miles on it myself. I have no idea how long the previous owner may have had it. The truck has a 4.8 with nitrous, cam and headers and has run a 7.98 in the 1/8 with a 1.74 60ft. Converter and trans. work great other than the lock up problem.

What i would like to know is should i send the converter back for a rebuild. I think the clutch is going out in it. Or is there some other problem.

 

I would say if the converter locks anytime then its not a converter issue. I would check the tcc solenoid first.

 

That"s good news. The truck and trans only have 30,000 miles. Would the TCC solenoid go out that quick. The trans also has a fairbanks valvebody kit in it.
