All electronic shift 5 speed 722.6 trans have a removable bell housing.

97 E320 / SL320 3.2 inline 6 cars for sure had this trans, not sure if 96 was electronic shift. ( Hydraulic shift had a vac modulator on the left side , electronic did not have any modulator. )

This bell hsg carried on to the SLK ( 230 ? ) M111 4 cylinder that could be gotten with a manual trans but power handling is limited. It may have also been used in the late 80's early 90's 190E. ( The 99 V6 uses more of a round V8 pattern )
