B16a gearbox problem.

[GSi_PSi]

Hey guys I recently been in process of replacing my gearbox , which I replaced and found my thrust bearing to be noisy so rippled it all out again and changed it , I reused the gearbox oil I drained and put it back in and now I cannot select gear 3 and 4 at all. It was shifting before in to all gears fine before, it doesn't select when motor is on or off. When installing the bitch pin I used the hammer to jam it in place instead of the power steering bolt trick. I might drain out the oil and replace to see if it has any affect. Really doing my head in. I didn't change anything from before I dunno why it's not shifting ...

Bump anyone ?

[Bludger]

I would doubt it's the GB oil mate.

something wrong on re-install, no one knows what you did.....

good luck buddy. Wouldn't be fun if these things didn't happen.

[GSi_PSi]

Would you have to put the gear selector in neutral ? Before you bolt in the shiftlinkage ?.

[Bludger]

don't know, never done it.

[GSi_PSi]

Lawl, cheers anyway bau wau

Did you try selecting all gears and spinning the input shaft before you put it back in the car?

[krillin]

You should of locked it in gear before box back in. if you can't select third gear try bleeding the clutch system again, or check the clutch master isn't leaking which is common problem. Also check the slave cylinder on the box. if you can select gears while engine is off then hydraulic issues.

[krillin]

Can you select gears without clutching?

[GSi_PSi]

Cannot select 3rd or 4th gears on or off , with or with out the clutch. I thought the gears where selecting fine before so it should be okay to wack back in.

just some general info that members need to help resolve this problem for you :

1.did you put the linkages on right way including putting the pins in?

2. did you put all the gearstick bushes back in? if you did remove it.

3. did you touch any internal part of the gearbox? main shaft, final drive sets etc?

1. I think I did ?. I put the bitch pin in by hammering it flat on the shift linkage and gear selector.
2. No bushes came out ?. I just bolted it back up with the washers.
3. No internals where touched except the clutch bearing which is still external and shift fork

[GSi_PSi]

Is there a way to install the shift linkages wrong ?.

[krillin]

no i don't think there is, though just asking to make sure as i'm only guessing the person who performed this job must be a "diyer",

bearing isn't seized?
put bearing in the right way?
the fork sitting on pivot correctly?
placed lock pin for fork on correctly?

if you are confident you have done everything correctly regardless, then you will have to definately pull out your gearbox and diagnose further causes.

that's all i can help at the moment

thankyou.

[GSi_PSi]

If above was faulty it would engage in any gear.... Fml I don't wanna rip out the box..
I overfilled the gearbox oil.. I dunno if that would make some issues

[krillin]

no incorrect, if the above was faulty it will not engage any gear,

so are you're trying to say everything i have listed above is installed correctly? + the gears would engage before?

then how come you can't select 3rd and 4th gear now?
it's obviously in the gearbox.

by the way have you tried, putting it in 3rd gear and releasing the clutch slowly to slow the input shaft down?

it's obviously in the gearbox.

please keep us posted on the outcomes.

[GSi_PSi]

you cannot select 3rd or 4th gear at all. even if you force it it will not let you, on or off..

i was meant to say if the above was faulty it wouldnt engage in any gear not just 3rd or 4th..

[Benson]

Might have damage the linkage when you hammered it. Or might have poped the selector out of place

[Benson]

I would take off the box and try to select all gears. If you cant get all the gears with the box out, then it will require it to be opened up and inspected

[GSi_PSi]

Yup selector was kinked to the side, I hammered it back into place now it's good to go but the gearbox rattles really loudly on idle ? I'm suspecting my slave cylinder is gone because it's not letting the clutch pedal come all the way to the top?. Would the loose pressure cause the rattles ?.

[amant02]

Wen the clutch cylinders are about to go in my experinece the pedal likes to stick to the floor before coming back up, feels werid. Only a 300 dollar fix @ most mechanics.

Sam.... easy to narrow down the problem

You do not need to step on clutch to engage into gear when engine is off, So if you think slave needs changing then change it, it will not affect you from changing to 3rd and 4t

If you dont want to pull the box out, I reckon you should take the linkage complete off from the gearbox, then stick a screw driver in the hole where the pin is, then pull selector In( 3rd gear), Out( 4th gear) and lets see if it will go in....

It might be the linkage as benson mention, if it still doesnt go in then gg.... remove box yo..
