hello everyone,

i am having a weird behavior from my tx and I winder what could be causing it:
when I am at a full stop, mu manual tx shifts normally.
when I am driving, sometimes, it locks and I won’t be able to select any gear.
So far, it can be either the hydraulic system : air bubble in cmc or slave cylinder ( i bled with the pedal and using a vacuum pump with no success)
it can also be bad synchros

the weird issue is the following. Let’s say i am
on my driveway which is sloped and I am in neutral, when I release the brakes the car moves down slope: normal and expected. However, if I shift to first, and fully push on the clutch pedal, the car won’t move. As if the gears are holding it. Now if I accelerate slightly and release the clutch, it will bump twice then start
move forward. Once it start to move, I press on the clutch and It will keep moving.

I can’t figure out what can be causing this. (I replaced the motor mounts already)

any kind of help is greatly appreciated

 

do you have clutch freeplay ? should be atleast a quarter inch, half inch is optimal

if your freeplay is good it's probably just the clutch

 

This is a brand new oem clutch, flywheel and throwout bearinf. When I drive the car the clutch is operating properly.
I do feel a clutch freeplay.

what i meant by the clutch is operating properly is that it seems that is it decoupling the tx main shaft from the engine. You can feel it disengage.
the issue seems to be coming from the tranny.
