did you put in a new bowden tube? maybe too little or too much bend in it.
maybe try letting clutch adjust out until you have lots of pedal free play then back
just enough to still have 25-30mm free play.
or maybe gear selector gate at gear stick is way out and needs re adjustment?

If it jumps outta gear that a g/box problem with the synchros. That means a rebuilt/new box.

If it's hard to get in gear you need to check how good the platic bush in the tunnel behind the lever is plus the rear coupling. Too much play in these will mean poor shifting.

Once they are in good condition you can adjust the plate under the gearstick housing as per the manual.

No no. On the gearstick it connects to a rod inside the floorpan centre spine. Just behind the gearstick is a support bracket that has a plastic bush for the gearstick rod to slide within and then at the rear of the floorpan spine is an inspection cover, under the rear seat, that allow access to the rear gear coupling. This has stiff rubber bushes in too but over time the rear coupling rubbers and the front plastic bush wear so you end up with a sloppy gearstick and difficult gear changes.

Also did you note the thickness of the clutch plate when the engine was out the car? If your clutch is low then even properly adjusted you will find it harder to select gears.

Replace bushing near gearstick. Clean grease and tighten rear shift rod bushing. New genuine Bowden tube and reset the gearstick mount once all replaced. Should be fine keep going

is a bugger cause each time i look at it i cant drive it hope i can sort it out soon

The gear shift coupling and plastic bush in the tunnel (near the stick),
are areas that should be replaced as a matter of maintenance over time,
but since you have replaced the parts in the clutch fork area, my guess is that this is where you should be looking.

Your symptom of difficulty with reverse and 1st/2nd, are normally associated with the clutch not disengaging.

This can be adjustment in either direction.
If the diafragm fingers are hitting on the disc when the pedal is fully depressed,
you need to back off the adjustment nut/wing nut.

but in usual instances, the adjustment needs to be wound up to let the pressure plate disengage from the disc.

Also you mention replacing the clutch pressure plate and fork?

Make sure the pressure plate is the correct one for your throw out bearing model,
and that your "new fork and bush" are not the crap quality ones that allow the bush to squeeze out,
and position the throw out bearing off centre.

Original VW parts in this area when ever possible!!

thanks dangerous i woke up nice and bright this morning and found out someone made an inspection plate above where the clutch cable clips on to the clutch and it was the outter tube the welds were broken up the front and back and the outter tube was pushed about 5 cm to the front of the car and i got my uncle to weld the tube back into place and for free of charge he even welded a crack that i had in the guard up and got bog over it and under coast i will paint it tomorrow this made my day now she is running beautiful no shutter anymore or gear changing problems

cheers for the help jamie
