1985 G52 Suddenly lost 5th Gear
« on: Jul 21, 2020, 12:23:04 PM »
Hey everyone.  I am new to the board, but not at all new to wrenching or wheeling.  I need some help figuring out what to do with my sons 85 daily driver.

He was going down the road and suddenly lost 5th gear pulling a hill.  No bad noises when it quit and none now.  The transmission does not have bearing noise and everything else including reverse is still good.  It almost feels like a shift fork broke; when you shift it into 5th now it is very easy to shift an doesn't feel like the gear is moving.  It also has a new clicking when coming out of 5th or reverse.  We drained the oil and found only a little bit of fine metal on the plug which I would consider to be normal. 

I have not had alot of luck finding information on this as a common failure.  I did read something about 5th pulling off the shaft, but I would have expected gear chunks or possibly grinding if it had moved on the shaft. 

It is also worth noting that on the rear plug if I reach in with my finger there is something in contact with the case right at that plug.  This seems abnormal.

I am planning to pull the rear section apart and inspect for damage, but I am hoping not to have it torn down long since school is starting soon.  Any help with what might be going on and potential fixes is very much appreciated!

I would not call it really sloppy, but it would not be hard to pull it apart and see if anything is wrong there.  We will give that a shot before pulling it out.

Thanks!
