At the Oscoda ProSolo a couple months ago I noticed a whining in 1st gear under decel after a couple full throttle launches. A few passes later I broke a rear axle, hub, and suspension upright. Anyway I finally got the car together and the whining is still present.

Here are the symptoms: loud whining when engaging 1st gear with clutch disengaged and the car stationary. The same whining is present while decelerating in 1st. No whining under acceleration in any gear.

Thoughts?

Thanks,
Eric

 

it sounds like either you TC or tranny.....possibly a syncro...i would take it to someone who really knows EVO driveline's

 

Normally I would suspect internal transmission parts with a whining sound. However, it whines loud with first gear engaged, the clutch disengaged, and the car stationary.... under this condition there are no parts moving inside the transmisison or transfer case....

 

what kind of clutch

 

Exedy triple plate

 

it might be the clutch...i have heard clutches wine a lot when being engaged/disengaged

 

and full throttle launches cannot help any situation.

 

You cracked the teeth on 1st gear.

Yeah and if you are going to keep racing it you might as well click the link.

 

my brother chipped a tooth of his second gear in the wrx. sounds like the same thing. sorry to bring you the bad news

 

Thanks for the responses guys.... I'll pull the transmission tonight to check it out. Looks like I'll be getting a dogbox sooner than expected....

Well I have the transmisison apart... no broken gear teeth and nothing obviously broken. Any more ideas?

Call TeamRIP or Shep racing and start asking questions

 

Have the gears been wet-Magnafluxed or just inspected with the eye?

Have the gear wear patterns been inspected properly?
