I don't know if the transmission in 300E's with the 3.0 liter M103 engine (1986-1992 300E's) is the same transmssion that is in 1993 300E (3.2) / 1994-1995 E320's.
I think the transmission that is in 1990-1992 300E's is the same one that is in 1986-1989 300E's. The difference is in the valve body or the control module.
sells a first gear start kit that can be retrofitted to your transmission.
