Outer Limits 4x4 Board

hey all, i have a td42 with a 5 spd, that crunches a little into 4th when hot, if i try change with any haste. if i ease it in it's ok. ive just done a change of 3/4 castrol vmx80 and 1/4 as recommended lucasoil stabiliser to try rectify the problem. has helped a fair bit but is still kinda there under a quick shift. any suggestions? and what am i looking at for a reco? thanks in advance :-)

im not sure on this but could it be the clutch not disengaging fully? put ur 4wd stick into nueteral and put it in 4th and let the clutch out slowly and listen for odd noises..

try shifting quicker

try thicker oil or some moreys.

Prob a bit worn from heavy towing

any more suggestions guys???

im told that this is quite a common problem with those vehicles fitted with a vac boosted clutch.

The issue seems to be when they get hot, the booster seems to be not as effective, and causes the clutch to not disengage fully.

I have yet to change to booster to see if this fixes the problem. I have changed the slave cyl, and changed fluid and bled the system.

4 gear syncro fault, seen lots, cheers

my old gearbox used to do it in 5th.
My new $200 box has started to do it in 3rd (after a couple of years though...)

so i take it they arent the slickest of boxes from new...

My old box was at the stage of having to run a thicker oil in summer to change smooth and a thinner oil in winter to change smooth.
