Maintenance / Re: Noise from transmission after dyno-test
« on: May 28, 2012, 07:16:33 PM »
Dear all,
after some ionvestigations, i have now solved the problem; as described, it ocurred only when accelerating...
I first checked the tranny-oilpan and the filter for debris - nothing. At all...
The i closely checked the flexplate for cracks aso... nothing. By coincidence, i noticed some blank metal marks on some of the tooths on the ring gear. I looked up on the startermotor, and noticed, that the centerbolt of the shift fork had fallen out... this caused the starter drive gear to "slash" back and forth- and of course, when accelerating, the starter drive gear hit the ring gear- causing this very (expensive) noise...
After mounting a new bolt in the hole, the car now runs smooth again- and i enjoy my 230 brake HP, measured on the wheels, in the beautiful danish summer ! :-)
Best regards, and thx again for all of your inputs to my case
