222k Mile Transmission advice

Unless the transmission is leaking there is nothing to top off. I think the majority of the horror stories about changing fluid causing transmission failure are from those that tried to solve an already existing problem with new fluid.

I spent quite some time with the techs and owner that work at a transmission shop that has done nothing other than European cars, primarily BMWs for twenty plus years. His input was to change fluid and filter every 50,000 miles and use only the brand fluid and type fluid that is specified by the manufacturer. I didn't ask if he would recommend changing the fluid after two hundred plus miles. If in your place I would have a well recommend transmission shop that works on BMWs diagnosis the problem. Parts guys or BMW dealers are not transmission experts.

I have 325,800 miles on the original fluid with no shifting problems. I average 4000 miles per year of towing a 1300 pound PWC trailer with a Thule rooftop carrier.

The only thing I would consider doing is draining the fluid into a clean container, changing the filter, clean the pan, refilling with the old fluid after running it through a strainer, and topping off with the appropriate fluid.

Then, save up $3500 for a re-manufactured transmission.
