GPX 4speed gearbox issues
Posted: Mon Apr 10, 2017 11:01 pm
Hi Guys,
I have started making miles with my GPX after a couple of years doing repairs / refit but i'm not really confident that my 4speed tiptronic is working correctly.
It sometimes bangs into drive like if the engine would turn itself around in the engine bay. Sometimes shifting is going very smooth. The banging already costed an rear engine mount and i don't want to mess up anything else...
The other issue is that i'm noticing vibration while accelerating between 20mph to 50mph. At 80mph it's starting again at high frequency with a humming sound and it won't stop until you take your foot of the gas. Could this be the torque convertor ?
The color of the fluid is red and has been changed 1500 miles ago.
can you advise ?
