just954rr Posted March 26, 2007 Share Posted March 26, 2007 Hola!..has anyone ever seen or heard of ATF fluid in the Final Drive ?...I had mine changed about 2 yrs ago...today i went to change it and when i drained it guess what..RED and smelled EXACTLY like ATF....any comments? Link to comment
Urban Surfer Posted March 26, 2007 Share Posted March 26, 2007 It probaly wasn't ATF fluid. ( I hope it wasn't) Red line makes a very heavy gear oil that is actually red, and does have a nasty odor. This stuff is really thick, unlike ATF fluid. Redline does not recomend it in the final drive, due to the fact that it can plug the small vent hole. Any way check the viscosity, there is a big difference. Link to comment
just954rr Posted March 26, 2007 Author Share Posted March 26, 2007 I'm pretty sure it's ATF..anyway i flushed it twicw and added the corrects fluid.....tranny as soon as i order the tool to remove plug..the last fluids change were done by MAX BMW..in NH Link to comment
Ken H. Posted March 27, 2007 Share Posted March 27, 2007 BMW's own newest synthetic is also red in color. My guess is that is what Max's used. It would be unusual for them in particular to goof and use ATF. Link to comment
just954rr Posted March 27, 2007 Author Share Posted March 27, 2007 I drained the tranny...it's RED as well..and smells like ATF..i'll call max BMW tomorrow and ask them,.. Link to comment

DavidEBSmith Posted March 27, 2007 Share Posted March 27, 2007 Ummm, did anybody mention that BMW's gear oil is red and looks and smells like ATF? (Actually, it looks and smells better than the ATF in my Exploder transmission . . . ) Link to comment
motoguy128 Posted March 27, 2007 Share Posted March 27, 2007 Ummm, did anybody mention that BMW's gear oil is red and looks and smells like ATF? (Actually, it looks and smells better than the ATF in my Exploder transmission . . . ) That's because the Exploder fluid you smelled was pooled on the floor off your garage. Fluid always smeels better fresh out of the container or gearbox. Link to comment
tio168 Posted March 27, 2007 Share Posted March 27, 2007 Hi, The main difference between ATF and actual gear oil is the viscosity. Gear oil is thick and syrupy whereas ATF is runny. If it had been ATF in your final drive I doubt if it could last a whole service cycle as the stresses on the final drive gears would have worn the gears out! ATF just would not be able to do the job gear oil is designed for ie prevent metal to metal contact even under extreme stresses and loads. Thanks. Regards Tio N H Link to comment
Clive Liddell Posted March 28, 2007 Share Posted March 28, 2007 I use what is recommended in the handbook: GL5 90 for gearbox and final drive on the bike. BTW my Mercedes manual gearbox specifies ATF (old "A" spec). Link to comment
