Hello all,
The Auto in my 5L decided today that it wont go into 4th gear, which on the highway where you need to drive 110 is a big big issue, taxing the motor big time.
Also a few other things the shifts between 1st and 2nd are very slow and quite harsh unless I drive the car flat to the boards. There also feels like quite a lot of vibration coming from the box, I can feel the vibration through both the left hand side of the drivers chair and the centre console. The vibration is especially bad when you've just taken your foot off the accelerator pedal.
All fluids including the transmission are all sweet and to there is no overheating issue.
Any help you guys can provide would be greatly appreciated as I need to drive back to Melbourne from Sydney on Thursday.
Edit: According to a website with a list of symptoms and causes of issues with the Commodore Auto apparently it might be the TPS (Throttle Position Sensor) " 1-2 shift is delayed and harsh, may not shift into OD: Check TPS for smooth and linear electrical response over the entire range of motion. If not, replace."
So I will do the yee-old paperclip diagnostic tommorow and hopefully that will give me some info.
