88 560SL Fluids

[Roncallo]

I used to work as a MB RR, BMW technician at an authorized dealer for a short time in 1987. At that time and I may be wrong, I thought we were using Dextron transmission fluid for all our cars. I just purchased a 1988 560 SL and notice that the ownwers manual says use MB transmission fluid and MB power steering fluid. I called MBNA and asked them and they said MB fluids are the only approved fluids for this car, but I think she was reading the same manual page I was reading. Are there any substites for MB fluids in these cases. Any recomended brands.

MB fluids are not exactly on the shelves at the local auto parts store.

Thank You
