So, reading this old thread contemplating whether to change my trans fluid on my 95 ti automatic. I'm inclined to check level, top off as necessary and have a spare, fresh tranny on the parts shelve.
In my car's case, it seems to run and shift just fine. I normally go through all fluids and filters, but paused on the auto tranny. I did change the "lifetime" fluid on my 540it at 70k. This ti has 364,000 or so miles, so, I'm thinking top off and renew everything else.
