Orange Posted January 18, 2006 Share Posted January 18, 2006 Morning all!! A quick question on the gearbox of our 1987 3.5EFi 5sp Manual - what oil should be in the gearbox?? I have been told previously that it should be filled with the oil used in the Auto box - is this right??? The reason I ask is that during the last few excursions in it, the drive has become very fidgety and clunky on over-run - i.e. when letting off the accelerator (still in gear) on the approach to junctions, roundabouts and the like - and when at low revs in each gear. Any suggestions?? Cheers Adrian Quote Link to comment Share on other sites More sharing options...
DEANO3528 Posted January 18, 2006 Share Posted January 18, 2006 Dexron II / ATF is specified for LT77 with EP90 in t/box. Later Borg Warner t/box takes ATF Best option is to buy some MT75 from Difflock, which is far superior to ATF The clunking could be Aframe ball joint or worn radius arm bushes let alone normal backlash from wear.

Orange Posted January 20, 2006 Author Share Posted January 20, 2006 Cheers for that! I don't think the clunking is anything more than backlash, but it may be more pronnounced if there isn't any oil in the g/box / transfer box!!??!! Tomorrow's job I think!! B) get's me out of the house!! Quote Link to comment Share on other sites More sharing options...

From experience with my trialer, which has the LT77s, it reacts very well with regular gearbox oil changes, it goes from a clunky to smooth shift Quote Link to comment Share on other sites More sharing options...
Orange Posted January 23, 2006 Author Share Posted January 23, 2006 Boy, oh boy!!! What a difference some oil makes!! Clunky shift has now turned into smooth shift, and even the diff-lock engages now!! Always a bonus!! Quote Link to comment Share on other sites More sharing options...
