Transfer Case Oil

basadan · 06-16-2018, 04:34 AM

Hi all. I've just had the gearbox and diffs serviced at 52k miles and the garage have said changing the transfer box involved removing exhaust and heat shields etc, then turning the box upside down to drain. After refill, re-assemble all the parts and you're good to go. So, would anybody know a reasonable amount of time to do this work?

Secondly, I've read that some F30/31 owners were having success removing fluid through a small rigid tube, any idea on the diameter of this tube?

i never did any of that.. i just removed the transmission mount to excess the check/fill and used a 1/4 inch clear tube to suck out the old and pump in the new.

Sorry to resurrect but did you reset any adaptations?
