Morning guys,
As title suggests, the 6 speed box in my '95 ABY coupe with 146k miles is generally notchy all the time although gets slightly better when warm. It never grinds but, you can feel something almost catching/baulking when shifting during normal driving and have to shift slowly so it changes ok. This is most noticeable on R, 1, 2, 3 & 4; 5 & 6 seem ok. When cold, it changes gear ok but after a couple of minutes starts getting notchy and second gear becomes difficult to downshift into. After a couple more minutes the second gear downshift issue is almost gone and when warm is fine. When giving it beans it changes gear quickly at high RPM's cleanly and without any noticeable issues.
I've gone to great lengths to ensure that the linkage is tight from the stick up to the box with virtually zero play anywhere. The gearbox oil was replaced a few months ago with Castrol GL-4 Syntrans (75/90) stuff which helped slightly but hasn't quite sorted it.
I changed the clutch master cylinder last year but not the slave although since I have no records of this ever being done, might be getting replaced next week. FWIW, the clutch has always felt a bit heavy but has always worked *touches wood*
The clutch biting point has been adjusted so its as high as I can possibly get it without pre-loading the release bearing and admittedly, is still only a couple of inches off the deck. I don't think its dragging but I haven't ruled that out completely.
I'm reluctant to go spending money on things unless I have a good idea whatever it is will actually help (already changed box oil twice in last year!).
So whotcha think guys:
1. try changing the slave and see how it goes
2. change the gearbox oil again (maybe Fuchs Titan Sintofluid 75/80?)
3. live with it
4. box is old and probably borked (see no.s 3 & 5)
5. drive it like a chav everywhere so it changes gear properly
Any suggestions greatly appreciated
cheers,
mike
edit: I don't know if its relevant but I'm sure when the box oil was replaced it was filled up to the hole rather than Xmm below. Is that an issue?
