gearbox leaking alot
« on: Aug 16, 2010, 10:56PM »
just bought a 91 trx 4 a grand with apr 2011 reg
car drives smooth engine runs fine but has a couple small issues
1) its leaking gearbox oil on my driveway, mechanic told me its coming from the gear selector seal
any one know how hard it is to repair
2) gearbox is making an annoying grinding noise in all gears including neutral but shuts up when clutch is pressed also shifts very smooth
been told 2 things from half a dozen people
mechanic reckons gearbox bearings gone and i need a rebuild $1500
and others are tellin me its the thrust bearing which came with the clutch kit i just bought (havent installed yet) bit worried if i install it id be wasting my time as gearbox would need to come out again to rebuild
any ideas

well i just pulled a manual gearbox apart myself, i can tell you that changing the selector boot wouldnt be a huge drama, not hard at all, just gotta undo one bolt pretty much....

As for the noise with the gearbox, sounds like your release bearing (thrust bearing). Smoothness of shift is not determined by this, so thats why the clutch kit should set u straight

Changing the boot wouldnt be a problem, however im sure there is a seal or something that is stuffed which is the reason its leaking as the boot isnt designed to hold the oil in.
