Question about 1999 Oldsmobile Intrigue
Hello I have a 99 Intrigue with a 3.5L.Would a P0742 TCC stuck open code cuase no engagement in any gear?
The car most likely needs a new TCC solenoid. These were a common failure in G.M. cars causing the symptoms you were describing. Other symptoms may include: shudder or stalling at stops, car lugging on acceleration, harsh shifts, etc. Car may feel like stuck in second gear on stopping and taking off from stop. I hope this helps.
