Overdrive heat

How hot does an overdrive get?

Mine gets bloody hot, transfer box cooler and main gearbox cooler still...

All have correct levels of oil in em, and she drives smooth and pretty quiet, there seems to be no 'drag' in the system as she freewheels easily.

Is the overdrive getting hot normal??

my one never got that hot, try changing the oil in it old oil doen't lubricate as well as new stuff

Had new oil in when I fitted it...

Refresh me, what oil 'should' be in the OD, i have GL4 gear oil at the mo...

what make is it??? old superwhinch/fairey ones should be GL4 ep90w (80/90w will do) more modern ones i am not sure, how long ago did you fit the overdrive??

Fitted it about 2 months ago, got it from ebay it a Fairey one...

Fitted a treat, new oil etc. gets hot over 20 miles,, what worries me is that its got 300 miles to do soon....
