Valvoline has an Import Vehicle ATF that they claim meets the Mercedes 236.10 spec. which is the spec. for your transmission. They also make a Maxlife ATF which says it meets the NAD-1 spec. for this transmission in Chrysler products but it is not clear to me what version went into Chrysler's. Your transmission may have the problematic input/output shaft bushing, and if so, I would feel better using a thicker 236.10 fluid. The bushing was replaced with a roller bearing, I believe some time in '99, and I would be comfortable using the thinner fluids on the modified transmission.
