After a dynotest with engine adjustment and an output test, i have unfortuately got an ugly noise from the gearbox or converter. The noise is only there, when the engine is pulling (lever in D). It sounds a bit like a piece of metal hitting the spokes in a bicyclewheel...
I did check the flexplate, and there are no cracks or messing parts- or parts hitting each other...
There aren't any other problems, the tranny (th 350 standard gearbox) is, apart from this noise, working perfectly, and the engine is pulling allrigth..
Anyone with a good idea to the cause?
