Wow dude no..... That's ment to say first not third :')
On further inspection I can hear a slight grind with every gear...
But second is by far the worst when downshifting.

How much play do you have in the cable?

Open in new window

1. On transmission (at the release lever): adjust for 3-4 mm play

2. Inside: adjust pedal (pad height 139.5-143.5 mm from floor)

3. Check pedal free play (11-15mm)

On transmission it has 3-4mm .

Is the pedal height measured vertically from the floor pan or from the back of the pedal to where the pad would hit if it wasn't connected?

And is free play measured by how far the clutch moves in by fingertip pressure before it stops?

Yes, fingertip or pinky finger pressure

Pad height is measured from floor mat (not carpet) to top of pad

3-4 mm is excellent and it means the clutch is releasing all the way


But if there is not enough stroke, it will grind when changing gears

Okay so transmission has 3-4mm
So pedal has about 40mm of free play :/

also do I measure pad height from the floor pan starts to rise up towards the dash?

40 mm free play is the problem, it will limit the pedal travel after the clutch starts to move


Measure as shown in the diagram


Does it grind when parked, engine running, clutch pedal down, and shifting into various gears? Try REV because it doesn't have a synchro

* If it shifts in and out of REV with clutch pedal down, then the combo is correct
* grinds on all gears with clutch pedal down, not enough pedal travel (pedal stroke)
* only grinds when car is in motion -- bad synchros

Oh yeah, there are two adjustments at the pedal end:
* small stopper at pedal to adjust the pedal height
* large nuts at firewall to adjust the cable play

So I have a 120mm pad height...
I'll test what you just told me.

So the combo is correct... Doesn't grind into reverse or any other gear when stationary...
Could pedal free play be the reason it has a bang out of the gearbox when releasing the clutch to take off in first?
