G60 - 02A 'box - jumping out of 5th Gear

[alackofspeed2 0]

Hi,

 

A friend is having a bit of bother with an AYK - 02A - gearbox, which will jump out of 5th if load is removed and reapplied. Further to this, when running in 5th a slight vibration can be felt, which isn't present in the other gears.

 

Another friend (biggerbigben), who had issues with 5th in an 02C gearbox, said that the 5th gear diaphram springs snap, resulting in dodgy 5th gear selection, and he suspected the springs have given out on the ayk gearbox.

 

Does this sound likely? The prospect of pulling the gears off, and generally messing around with stinking gearbox fluid is very unattractive, so it'd be good to know the right part is being targetted before starting!

 

Thanks in advance for any help.

 

John.

Does the gear stick physically move out of 5th aswell?

 

Might be worth speaking to Vince at Stealth Racing as there's nothing he doesn't know about gearboxes. He used to build them for a living.

The gearbox comes out of 5th, and the lever returns to the neutal position. I'm not convinced it engages properly to be honest, and this isn't a function of the shifter in the car, as when selecting 5th using the tower,it doesn't appear to move as far "forward" as it does for 1st, and 3rd - something appears to be limiting the movement.

 

It would be useful to speak to Vince, but as I wouldn't be sending any money his way, I'd be taking liberties.

It almost sounds like the old issue of O2O gearboxes. Try changing the fluid and see what that does, then see if you have a broken or bent shift selector cable.
