Thread: Another Teg issue...

  1. #1

    Default Another Teg issue...

    Okay, that cold snap a week ago brought another problem to light with the Teg. I took off that day when it was close to freezing, and after I hit over 20 mph I noticed a weird bumping sound coming from around the tranny (!).

    1. It sounds like it's coming from just to the rear of the front seats.

    2. You can only hear it under acceleration; when coasting it stops.

    3. However, the sound corresponds to wheel speed, not engine speed.

    4. I can feel the bumping in the pedals.

    5. Rate of bumping is about 6-9 times a second at highway speeds.

    Any ideas on what this could be??

    You say "around the tranny", but then you say "from just to the rear of the front seats". It is a FWD car, so you can't have both???

    Did it go away when the car warmed up? Could be cold, hard tires that are not completely round after sitting over night or longer.

    Had a chance to look underneath yet? Any leaks or puddles? Boots intact?

    Maybe the tranny's trying to kick its way out.

    It sounds like it's coming from behind the seats, but it feels like it's near the front. I don't know how to explain it

    I will say that it's only happened when cold, but once it started after I had been driving for a little while and not right when I had started off.

    I don't understand why it only bumps on acceleration
