I am so frustrated with this car! If anyone could help I would greatly appreciate it.
I have a 99 Gs 400, it looks great but is running worse and worse. I have had it for 2 years and it has 125,000 miles. The engine is strong, its the tranny thats worring me....
See the check engine light randomly turns on and the code reads p0763"shift solenoid C- Circut Electrical"
When the code appeares the car shifts hard mostly into second and third gear and the manual mode doesn't work, it flashes the M on the dash but won't let me control the gears. If the light is off, it shifts like a charm.
The Dealer refused to fix it unless I payed them $4 grand for a new tranny. So I took it to a mechanic and payed $700 to replace "shift solenoid C", power flush the tranny and put new fluid. The mechanic said the tranny looked great and that there were no metal shavings in the pan. After that, It ran ok for about a week and then the same thing started happening again, same code pops up. There are days i don't see that check engine light and others that it won't go away.
Somebody please help me! :cries:
Thank you. The weird thing about it is the computer read shift solenoid c, so the mechanic replaced it. Now the code for the engine light is saying the same solenoid again. Its so frustrating. I'm thinking maybe I just have to replace all of them.
