Australian Car Repair Issues? Ask an Auto Mechanic for Answers ASAP
Hi Im David, thanks for visiting the site. the test that has never failed me is the vibration, more vibration in drive, and vibration in reverse. Vibration in P and N much less but there. If you turn the AC on, the vibration in every gear becomes 70 percent less. This is exactly the same diagnosis I have had with every broken mount I ever dealt with. I would also put one foot on the brake and put it in gear and with the other foot give it gas and watch the engine jump.
.the most likely cause is the transmission mount then. if it were the other motor mounts, you would definitely notice it when put into gear it would thud.
I have plenty of experience with the x drives, but not with the diesel. I will opt out and let another tech chime in who may be able to help. good luck.
