Gearbox Additive Suggestions?

[mrben]

Hi chaps. Could anyone recommend a gearbox additive? its got a horrible crunch going into

second and third, especially when cold, and feels generally tight. I can't actually clearly see

where you put the gearbox oil in (I havnt got the haynes for this car), so a bit of direction would be

appreciated. Cant see any obvious signs of a leak...yet. If there was a leak, is there an additive

to potentially stop this also?, as I know there is some pretty good water system stop leaks out there...

2001 diesel, 6 speed. 140k.

Soulds like its lost its oil somewhere - the usual place would be where the CV joint comes out of the box.

 

If its the same as the 5 speed there is a fill plug at the front end of the car - its a 8mm allen key fitting i think from memory, you remove the plug and fill till oil starts leaking out again with the car on level ground. It might be worth having a look if you can see the plug, and removing it - see if theres signs of oil coming out, if not then add some.

 

Could be the sign of a few other issues - Check the brake fluid level, as its a shared reservoir, If its got low and been topped up, or been changed recently it may be that the slave cylinder needs bleeding, and is causing the clutch to drag slightly. Theres also been posts regarding debris getting caught in the selector mechanism, fix is a case of cleaning the selector (have a look on here i've seen a few posts regarding that)
