I’m planning on changing my transmission fluid next week in my 1993 300D with 203k miles (W124 with a 722.418 transmission). The fluid and filter were changed recently (3k miles ago) so I’m just planning on doing a drain and fill to put in some Pennzoil High milage ATF and some Lubegard Red.

I’ve read the forum a lot trying to collect all the info I need (in addition to the service manual I have) but still have a few questions.

1) I was planning on using ramps to rise up the Benz but I’m wondering how I’m going to turn the torque convert to get to the plug without raising the back wheels? Do I need to jack up all 4 wheels using jack stands?

2) I was just turning the torque converted with a big screw driving, will this work?

3) What size tools do I need? I know that I need a hex for the torque converter but I don’t know what size. What size do I need for the removing the engine compartment lower panel? What about the drain plug itself?

4) Any additional “gotchas” I might need to know about specific to this Benz’s ATF change?


Thanks,
Paul
