Hi,Everyone.How are you all?Great site to be on..
I need some Expert help!I have a diesel 80 series.The manual gearbox had a terrible rattle when getting up it.Easing off it would go away but soon as i would accelerate again it would rattle like a my mum mouth going off!!I had a new input bearing done,oil change bushes,sincros as i could not change gears back to second.When it was put back in it went fine but its making the noise again!!!plus,i cant still get it back into second gear!!It is stressing me out as its money spent again.It had a 5inch lift kit in it when i bought it but but everything modified perfect underneath!Would it have anything to do with the lift kit??But mechanics told me it was sitting perfect gearbox.Would it be the flywheel?The pressure plate looked new when we took the gearbox out.The flywheel look a bit on the rusty side.I dont know what to think.Can some Man help me?plz......

It is not good. AFAIK your lifting only can upset transfer case, and even so 5 inch is not too much for it to happen. But if you have problem with gearbox and particularly cannot shift back to second that most likely it need to be completely rebuilt. It could be possibility that your clutch drag and you have difficulties with second, but clutch has nothing to do with noise. Dragging can happens because input shaft splines dirty or burred.
Good Luck

Hi Joanne
Something similar happened to me with my series 80 except for the gearbox noise when travelling. I could not change from 3rd to second at all when it was cold. As soon as it warmed up no problems. My mechanics fix was to clean up something to do with the syncro (cone??) I am no mechanic. He also suggested I use a different oil. I use VMX-M (I think that is what its called) and presto no problems.
Mine has a chatter when idling but noise goes when revs increase.
Cheers
Howard.

Yep, Castrol VMX-M is the best oil to fix the shifting problems in the Toyota boxes.
Bit hard to know whats causing the noise, from the description given - might even be the clutch.

buy a new
seat for the shifter ball, and run vmx....as far as rattle goes, if you have a consant, it will be your front tailshaft out of harmonic balance...the diff end is straight and the transfer end is on a descent angle, they dont even eachother out. double cardon shaft will fix that
