[DeTomaso] ZF chatter

[David D Fisher]

Thanks to all the responses.   My guess is that Chuck E is correct and nothing is actually wrong.   It's unlikely to be the throwout as it doesn't change with clutch action and if it was actually a loose bolt or something flying around in there I'm sure it would have jammed in a gear by now or at least made sounds like it was.  It's more of a chatter sound.

Dear David,


               I do believe that I have the same issue with both of my Panteras.  IIRC, while up on jackstands, with the engine idling even my non-mechanic ears would pick up an irregular rattling from the ZF. IIRC, I checked with some more experienced Pantera owners and maybe even Dennis Quella.   They told me that it was a normal phenomenon and did *not* mean anything expensive.  I have put more than 80k miles on them since I noticed the sound.  They shift fine and drive fine.  I *think* that the sound you're trying to describe is OK.  I *cannot* tell you exactly what is producing it from inside the ZF.


                            Warmest regards, Chuck Engles

It sounds like gears rattling on each other, but it doesnt have a period or rythym to it, almost more like a ball bearing being thrown around randomly.    It's just loud enough that I can hear it with the deck open and standing right over the engine, but not from inside the car.  I've been wrenching on cars for 4 decades and I have to bin this one in the "that doesnt sound good" category, but the box seems to work fine, other than a weak 2nd gear syncro.
