I have a 2008 awd Saturn Vue, it has 3.5 liter engine.The engine light came on and shortly after the performance of the car was marginalized. I had auto zone plug in a reader and two codes came up P0700 and P0752. After this was completed the light went off. The light was off when I brought the car to a cadillac dealer, who ran a history of codes for the Saturn. The following is the history of the most recent codes P0700/TCM request mil P0989 trans fluid pressure switch #5 circuit low voltage P0877/pressure switch 4 circuit low voltage P0752/shift solinoid. Cadillac recommended trans control module inside trans needed repair or replacement. What do you think? Can you make heads or tails out of this diagnosis?
Wife was driving the car, she expierenced loss of power, sluggishness, unable to exceed 30 mph, can't say about slippage, there was no dropping out of overdrive. The most significant aspect was the lack of acceleration. After some continued driving car seemed to respond better.
Is this something that needs to be addressed immediately? I'm looking at a costly repair; can this be done by someone other than a dealership? Since the transmission doesn't have a dip stick and I had all the fluids changed is it possible another transmission flush would do the trick?
Considering your experience and knowledge, this is a real problem. I can wait tohave it repaired but most likely it will get worse. What needs to be done and can you give a fair estimate of the cost?
Eric in conclusion Is this a real problem? How much time before car is not driveable? Is it safe to drive?
Thank you for your help and consideration
The solenoid was only part of the problem and your estimate of labor time and cost was way off. How much did I pay for this advice?
