When going for 6th while driving lift the reverse gate and carefully try and get it, if this let's you get 6th there is 13 mm nut on the gearbox selector which adjusts the left to right movement of the linkage, you will need someone to sit in the car while you adjust the linkage, good luck
Old thread but would like to get some help myself.
I had these fitted in mayor overhaul. Gearbox repair, Q2, new clutch etc.

But after the upgrade the 5'th and 6'th are hard to engage, unless I double press the clutchpedal and even then it engages when pedal is compleatly flat to the floor.
Other time there is no problem, goes to 5th and 6th with no big hassle.
Also tried that trick, when gears doesnt want to to place and you lift the reverse gear knob littlebit. Then gears go in very easily and clutch is only pushed a little...
Went back to dealer and said that this is the problem. I guess they didn't find it out before by their own because it sometimes works flawlessly.
They tried to fix it yesterday for many hours, but now 6'th seems to go in OK, but 5'th is way worse than before. Now it wants to go far to the corner, but it shouldn't.
They admitted that this is new problem to solve for them and they dont exaclty know how.
Thats why I am here
