Shifting problems

[innozent]

Shift fork? Looks like so much easier than changing the synchro

The clicking noise could be due to a stuffed drive shaft.

The spinning sound could be due to stuffed wheel bearing(s).

i got the clicking nosie when turning as well, drive shaft changed and its still there..

I really dont understand why would it become harder , very hard to shift after i drove it for an hour. I changed transmission fluid already, whatelse can it be

[tekung89]

dont drive till u find out wat the problem is, forcing gears will lead u to a new gb. bleed ur clutch yet?

Took the gearbox out. Check inside gearbox, input shaft seal is gone, the leaking oil
went into friction disc, make it not disengaging properly. Gearbox specialist inspected the gearbox, no worn synchro or bent shift fork. After putting everything back, the car will not become harder to shift after driving a while.

But 1 thing still happen, second gear pops out when up shifting. It feels like the second gear stick position did not make the gearbox put into second properly.
For example, when people shift into reverse in Honda gearbox, sometimes it didn't go in although the gear stick is in R position. with clutch engaged, clutch out. there will be some spinning sound near the gearbox. It feels similar to how i cant put into second.

Notes:Gearbox oil level Checked, up til that bolt.
Master and slave checked, no leaks.
Original Clutch disc with oil has been cleaned with oil cleaner, I didn't feel that it slips and disengaging not properly. Gearstick form reverse can be pull back to N easily
Will it be the shifter problem or the stabalizing bar of the shift linkage lead to this problem?
Any idea would be appreciated

did u find out what lsd it is when u opened it up ?
try another lsd oil like endless or cusco

Normally for 2nd gear to pop out, the dogs on the 2nd counter gear are worn.
The problem with reverse is due to straight cut rev gear & wear.
Generally as the 1st / 2nd sleeve carries the rev main gear, slotting the gear box into 1st gear before reverse will almost guarantee reverse selection every time. Unless something is seriuosly wrong.
This problem in 2nd is usually only present with syncro or seltector problems / wear.
It can be an assembly issue, but is generally only found in 3rd & up as there is no torqued nut on the input shaft. Incorrect shimming can do this too. But as you had a gearbox specalist lok at it, it's unlikley he got that wrong.
If the box comes out again,, look at the following parts.
(in ref to the pic you posted previously)
Slector fork # 3, the part that coreseponds with part # 5 & the mechanism that drives it.
If the main pivot pin is fouled or off angle slightly, the same can occur.
If there is an assembly problem, IE: 1st & 2nd gear outer syncro rings swapped acitently, the same can also occur.
NB: It's rare to be able to foul or catch the pin off angle without cracking the case.
NNB: When the syncros are fitted arse about, the shim clearance becomes incorrect causing the syncro to feel tight & not follow through.

The shift stabilising bar generally only causes issues when there is a problem with the bushes. round one at gearbox end & odd shaped 2 bolt one at the rear.
Both need to be in good condition & secure.
Engine mounts can cause similar problems but I expect your gearbox guy would have checked these for you.

Last though, it could also be an over torqued detent ball carrier.
When these are over torqued, the carrier rather than the ball makes contach with the shaft of the selector fork & this can cause similar / same issue.
These can be accesed without removal of box.
Hope that helps.
Cheers

very detailed information, thanks

Try getting new gear box oil.... bring it to HANNY"S 50 bucks.. oil is think but when it gets hotter obviously it gets thinner so maybe its low on oil and not enouhg lubrication!

Questions again,
1. will worn synchro lead to hard to shift in other gears after a while of driving.
2. Besides of oil, what else can lead to hard to shift after a while of driving, like 1 hour.
It was smooth at the beginning in first gear, third, and forth, fifth. It becomes harder after driving it for a while

[omgzilla]

As heat increases (after driving) the viscosity/thickness of the gearbox oil changes.

yeh i knnow, just wonder besides of oil.
it must be incorrect clearance to lead to hard shifting when hot ?
