1987 BMW 535is Transmission problem... HELP!!!! on 1990 BMW 535i

My Transmission started slipping and and then finally going up a hill would go forward anymore but reverse is like new. The Fluid is clear but smells like it's burnt.

Sounds like worn clutch plates. It's time to rebuild the transmission.
I'd suggest a diagnostic from a transmission shop.
