Whirring Noise When Shifting Gears
Hi, '92 six speed manual with less than 24K. Lately I have been hearing what can be best described as a 'whirring' sound when shifting in low gear & once when shifting into reverse. This doesn't happen all the time, only intermittently. My mechanic was unable to detect it while test driving. He changed the transmission fluid & for a couple of weeks-no noise. However I heard it again yesterday. Appreciate any suggestions of what may be causing this.

Has the tranny oil ever been low? Was this the first time it was changed?
Presume you know automatic transmission fluid SHOULD NOT be used in the ZF tranny...
What type of 'fluid' did your 'mechanic' put in (GM C4 tranny oil, or BMW Castrol TWS or something else)?

Go over to zfdoc.com and look at the Q & A page.
To me it sounds like the clutch hydraulic system maybe a place to look, that is assuming that the correct trans fluid was used by the servicing mechanic. The zf6spds do require a specific fluid. The newer GM stuff is not exactly what came with the car as GM has no interest in having a special fluid made. GL3 rated fluid is what the original fill was when our cars were in production.
