Just the day after a meet and 300 miles in a day, she starts jumping out of 5th

Keeping hand on shifter to feel what's going on: it sits quite happily at 70 (same road two nights in a row, eh??) it simply jumps out of gear, revs jump 2-300. If I have a bit more of a hold on the sifter: jumps about half way out (car keeps going), needs clutching to put back in.

MB6, S9B tranny, shifter bushes & linkages all fine, "new" clutch.

Long story short - help.

Dan.

 

I had this same problem when i put a new trans in my integra and forgot to add fluid to it. I realized it I never added fluid and topped it off, has never popped out of 5th since (5th was the only gear it did it in)

I would of normally never done such a noob move but I actually replaced this trans on my back, on the side of a major highway and in like 4 1/2 hours lol

so just check to make sure your fluid is topped off, if not its probably a bad syncro issue. I'm sure RonJ will be around shortly to chime in.

 

Kevin, I am glad you had a potential solution as I was stumped on this one. I'll be interested to know whether low fluid is the answer.

 

Side of a highway? That doesn't sound like fun, hope it wasn't raining aswell!

I'm check again tonight after work, but I'm almost certain it can't be the fluid level unless there's a leak somewhere. I had to drain the fluid to change the clutch, it's got about 85% brand new fluid, the rest was about 8000 miles old as I changed it about 6 month ago.

 

ok, so I've checked the fluid, it took about 300ml to make it run out of the top hole, somehow the bolt wasn't as tight as I'd normally put it, but never mind.

We put it on stands and ran it in the garage tonight, it tries to whine a lil bit in 3rd, whines at a low tone in 4th, whines at a higher tone in 5th. I'm wondering if the end bearing on the mainshaft is dying, but I don't know the order of the syncros on the inside. Is it (going from the engine side) 1,2,3,4,5 ?

Apparently repair parts have to be genuine from the dealer, says one rebuilder. So I'm on the hunt for an S9B tranny if anyone knows of one sitting and how much it is :wave:

 

My trans did the same thing (and only in 5th) one time when i forgot to add fluid.... then i blew my differential. Bad times. It would be fine during acceleration in 5th, it was only when cruising in 5th that it did it.
