Can anybody help me, think i've made a big mistake.
Just got a foutrak, was going to tidy up, MOT and use.
Thought I'd top gearbox up with oil. So undid what I thought was oil filler. However I think i have undone a bolt on wrong side of gearbox, i.e. passenger side, whereas think filler is on drivers. Anyway when I extracted this bolt, i thought i heard something drop or move inside box. Did bolt back up, however gearbox will not go into first gear as its stands. Havent moved or started it as worried Ill shred gearbox or something. Can anybody help me with this or shed some light, have I screwed up royally or am I just being paranoid and should I try see if fourtrak moves. What is this bolt on almost opposite side from oil filler, Much appreciate any help, thanks.
Also front diff filler wont shift, is it ok to put a little heat on this to see if it will move, or will i just damage casing or internals
