Trans/Diff noise. Will it go boom or naw?

[TDavis]

I've had a whine in 6th gear since I got my ST 2 1/2 years ago. I did a 2-1 shift on a pull last June and it started whining in every gear. Something just let loose inside today just cruising. I pulled into a parking lot to see if any fluid was leaking out. Trying to reverse out of the parking spot it was bogging a bit until something clunked and it it rolled back freely. I limped it home, but on the way I noticed the noise only occurred with the clutch engaged and was quiet with it disengaged. I was going to get a low milage trans (Mine has 115 on it) and get an LSD installed. This thread has me a little spooked though.

I've grown to live with it. Its stayed the same volume for the past 30k miles/3-4ish years with numerous tracks days on it too. I'd figure if something was wrong it would've happened by now

Yes this has gone past the whine to a full blown failure. You can move it, but it gets hung up at a point until it frees up again.

Ill bet it was something to do with the DMF* Dual Mass Flywheel. Drain the fluid into a clean basin and run a magnet through it or use a cheesecloth and stain the fluid through it and look for metal particles.

I think mine is shot, too. It makes a grinding sound when turning the wheel while on a lift and sounded like a rock to metal scratching sound when driving on any speed. Should I get a Clark or go with Pumaspeed?

Not diagnosing, but I went with Clarke, am poorer but happy. I read into postings with pumaspeed stories, good&bad, went to Clarke. Stringent core policy. And you remind me - time for a BG fluid change.

Well....Spend more and get service Stateside* or Spend less and roll the dice with no Service stateside.

I still don't understand why Clarke doesn't recommend the shift linkage mounted short throw shifters. So many people use them and have 0 problems.

Just like how he doesn't recommend anything but FOMOCO Trans fluid even if the Mftr. meets the Spec of FOMOCO*

I actually could not get him to name a fluid brand...

 

[TDavis]

Wonder if he actually has a reasoning

CYA? (or CH{is}A??)

i have whine in every gear and it scales by both engine RPM and car speed... it's weird. car has 167xxx on it and i'm just living with it. Ron now sells a bearing kit so I might pick it up when it comes time to do my clutch. no issues in any gear beyond the very loud whining
