I4 manual shifter weirdness
« on: June 16, 2008, 02:38:52 PM »

So Friday night my shifter jammed in second and I basically had to force it to get it out of gear.  For the next few shifts all the gears were 'sticky' and then it suddenly got as light as though the shifter wasn't connected to anything, though it still shifted all the gears but seemed to catch on every gate.  I thought I'd broke a shifter bushing (they're plastic right?) which first jammed then cleared when I forced it out of second (that seemed to explain the sudden increase in play) and ordered a short throw with bearings from the local performance shop because I'd always wanted one anyways.  I had the console peeled yesterday though and all the bushings and linkages appear fine.  From this thread I was thinking it could be that a shifter cable has split, but the more I drive it the more it feels like a spring let go on the 3/4 fork, it doesn't pop in and out of gears anymore, you have to pull it out (though it takes zero force to do so) and hunt for neutral. This morning 3rd and 4th kicked out hard a few times as I clutched out, fortunately my hand was already off the shifter.  At this point I'm leaning toward a tranny swap for a re-man unit, but I'm curious what you guys all think about it...

Could be a bad throwout bearing.  Be careful you can screw your whole tranny if it is.  If it was sitting in there weird and then it popped back in place it could cause that feeling.  And a bad throwout bearing will cause the tranny to kick out of gear do to vibrations.  Also possibly a bad clutch.  Do you have any slipping?  Put it in third from a stop get on the gas and slowly let out the clutch.  If the RPMs climb then your clutch is shot.

Could be the tranny but not likely the NV's are a pretty big powerhouse when it comes to trannys.

i drove a car like yours the other day at work, didnt want to stay in gear, the shifter would physically pop out and neutral was tricky to find. to top it all off the clutch saftey switch didnt work properly.

so normally i get in turn the key then push down the clutch til it starts. yeah, it just started, in gear, lurched froward into the curb Shocked

I doubt if it's clutch related because if I sit on a flat and clutch in with it still in gear the car doesn't even try to move, so I know the clutch has fully released the engine from the tranny.  That, and the weird behaviour in the shifter is the same whether the clutch is all the way in or (with the engine off) all the way out.  The launch feel hasn't changed any either, so I'm fairly certain it's something between the shifter and the actual gears (well okay, dog clutches and synchro cones) in the tranny.  Something that's external and cheap to fix I hope; I'll be pulling the battery tray and inspecting the cables this weekend.  Thanks for tossing out ideas though, very much appreciated and something to remember if I have other problems down the road.

The good news is that the 50% short throw made it 50% less noticeable...   Grin

Yep, I was picking up my car the other day after some work was done and had been driving an automatic in the meantime so I just pressed the brake a bit and turned the key.  Lurch!  Guess my safety switch is gone too...  It annoyed the hell out of me because I always leave it in neutral and use the parking brake but the shop tech had left it in gear and didn't pull the parking brake.  Gah.

The main problem was the detent spring, there's a sleeve around it that holds the ball against the spring and the sleeve split dropping the ball into the pan and spewing bits of broken sleeve into everything.  Fortunately no other damage was done from this, other than the spring sticking out too far which is what stuck me in second.  I conveniently bent it out of the way when I forced it back out.  (Hehehehe...)

Good call on the throwout bearing, since mine looks like this:



(I know... it's supposed to be completely smooth!)

The bell housing was also full of oil, including some smeared all over the clutch.  Ooops.  The whole thing's being rebuilt now with a synchro kit, throwout bearing, clutch, shaft seal, detent assembly and a replacement CV boot for the one that had grease coming out a small hole.  Oh, and they discovered my lower rad support is rusted right out and not really supporting the crossmember that holds the whole damn tranny in.  They're going to weld something in to hold it temporarily but it's back to the body shop real soon!

(Don't ask me the cost; somewhere between ouch and poing!  But I've put seven times that into this car already, so in for a penny, in for a pound...)

I'm guessing thousands?  That suck but at least you know what the problem was!
