Goodmorning all,
I've recently just picked up an Auto Wagon and after a trip to the end of the street and back, I've concluded she's rooted.
I'm seeking some professional (or not , if you've experienced these issues I'd love to know) opinion on some issues I have.
Issues
First off,
I've noticed that my Park (P) is grinding when putting the lever into it and if the car is off, it doesn't grab at all - car rolls (shouldn't be normal?)
Secondly,
Drive (D) and Reverse (R) don't appear to grab at all after about 10s of the motor running.
e.g. When I first start the car and put it in D, it'll grab and the car will start moving. After a while of running, once put into D it will roll backwards (if on a slope) and after some rev's it "might" grab.
Will also add on that at this point, of only 30s of the car running, I have the AT OIL TEMP light flashing at me
With all this I code a code P0720 and P0700:
P0720 - Output Speed Sensor Circuit Malfunction
P0700 - Transmission Control System Malfunction
Theory
Initial theory : The P grinding shouldn't happen at all... correct? - P shouldn't have any kind of spin as the Rear Driveshaft should be stationery with the car...
So initially we thought it might be that something has happened to the Rear Driveshaft, which is causing the P grind sound.
With this theory it would explain why it feels like the gears aren't grabbing - I remember in the past dropping the rear drive shaft in my dads car after the viscus rooted itself and it behaved a similar way.
Any input or theories would be amazing.
Thank you all!
