So, A problem with 5th gear. Always been there since I've had the car but might be getting worse. 5th gear crunches BADLY. Sometimes cannot engage.

If I'm very quick it goes in with a little crunch. If very , very slow, it mostly goes in.

However changing gear normally is crunched very badly - I'e' like not disengaging the clutch at all.

The odd factor is that it slots in beautifully ant the crunches when I let the clutch out. No crashing at all with the clutch depressed, only when the clutch is lifted, so I'm not sure it's synchro rings.

It seems to shift 'OK' mostly below 40 mph, and above that if I shift into 5th but move the lever to the left so I'm almost selecting 3rd after I go through the gate, then I can get it to shift cleanly every time.

Almost like it's selecting 3rd and 5th at the same time.

Ideas?

Done the oil but no better - I had hears about the bushings, is it possible to strip these out and change them without dropping the box out of the car?

Thanks all - Took some advice from Ashcroft transmissions and will adjust the lever centre point.
