Hellp,</P>


I have a 1991 300E with 230k miles. The car runs perfect. Exept lately the tranny shifts late and some times downshifts onm me. If I slide it into reverse then back into D, it usually normalizes after that. Them may slip again. </P>


This only happens when its engines has run for a while.</P>


Any tips or ideas?</P>
