GQ Gearbox Question

In the last few months my gearbox has been a bit crunchy on changes, a few weeks ago I lost my gears for a minute on the shift pattern, then everything went back to normal. I put a TB42 motor and new clutch in 6 months ago, I had the oil changed in the gearbox 4 months ago, I rebled the clutch last weekend and thinking today maybe they had put 90w oil in instead of VMX80 I decided to change it again. There wasn't any metal on the magnet plugs, oil looked pretty black, not sure if it had been changed (I watched it being changed 2 years back) putting my pinky up the hole to have a feel around, I found something, and with a coat hanger & long nose pliers I extracted a slightly mangled roughly 80mm extenal circlip, anyone know where in particular it's from and if it's important?

It was put there for show.. :armsup: :armsup:

Im thinking that you will be removing gearbox for rebuild soon, it wont be something you can ignore, things in gearbox need to be there!

with my gearbox i find it hard to change from 1st to 2nd when the car is cold. is this normal?

it is really stiff to go into gear but only when cold.

i have a tb42 with manual (obviously, dah!)

Maybe I'd better put it back :-(
I'll hopefully know before I head to Luvuka on the Australia day weekend

Normal as long as its not worn out.

Can be releived a bit using Shell helix synthetic etc.

theres a large circlip that goes into the top of the box where the gearstick sits...maybe its that and the stick moved and didn't allow gearchanges.

worth a look

Thanks, that sounds like good news, I'll have a gander at a spare at a mates place then get a new one and have a go at fitting it through the floor hole, better news than changing the box, hopefully the lack of damage to the circlip indicates it's only been loose for a few weeks.

Maybe I also need to look into my clutch adjustment.

GO the CUT & SHUT! Hope it turns out ok. If it still going that is good news. You may know a certain person with another box to have a look at, or he may have a genuine manual.

GOOD LUCK

PS - we are back

Looking at the manual pictures it appears to be a syncro spreader ring, there's one for each gear 1-4, still drives ok, 3rd gear seems to be the one that crunches more often, maybe it's that one.
