Title: Transmission Oil Capacity
Post by: Crossrodes on July 11, 2008, 08:08:11 PM

My transmission spec calls for .8 litres of fluid.  Because of the method I use to fill it,it is difficult to measure accurately.  In the past I know vehicles were designed such that when you filled a transmission or rear end it would be full when the fluid reached the fill hole.  Is this true for the R65?

Yes and no.

As I found out, the final drive can have too much oil it in when using the bottom of the threads as a fill mark.

I still haven't drained mine and put in a measured amount, but on a recent all-day highway run, mine made a mess.
It seems my 20 minute commute is not enough to get things in too much of a lather... ::)
Maybe I will get it changed this weekend.


The transmission may have more room for error, but one of Duane Ausherman's (http://w6rec.com/duane/bmw/index.htm) favorite sayings, is "a bit too low is better than too full".
