92' 500E Transmission oil change

hi,

My beloved 92' 500E is in top shape as I like it to be always,I like to know the transmission oil change intervals for severe use ie. hot weather I have changed both the oil and filter 2000km ago.Is it wise to use synthetic ATF opposed to conventional?? thanks

Filter every 30K miles, fluid every 15K miles (including torque converter).

No synthetics needed. Only approved MB's approved ATF.
