2002 Cadi Deville; the SES light came on about 3 wks ago and after my ODB code showed P0741, I had the trans flushed and fluid changed. Drove about 300 miles and the code has come on again. What is the likely cause; clutch excsive slippage, faulty slnoid, faulty connectr or wirg, or worse?
-
Will this cause the car to stall when there is quick deceleration like making the U turn on the access road?
-
Yes, it is possible that the code is related to the stall problem. Have you check the transmission fluid level?
-
I just had the tcc solenoid changed to a brand new one. Cleared the codes and drove it about 50 miles and the check engine light came back on with the same p0741 code saying tcc was stuck off for a predetermined period of time. What should I do now? You think I should keep driving it till it goes off by itself cause it's not used to the new one or what should I do next? Just spent $1200 to change the solenoid. Need some good advice!!!
