Is there any temperature sensor in the 722.418 transmission that can be replaced at low cost?

The transmission of my 318 kilo-mile 1992 300D shifts fine when the transmission of fully warmed up (except some banging when changing from R to D).

Before it is fully warmed up, shift quality is not good especially at gentle acceleration. The car often bangs and its front lifts up at 1->2. The engine revolution sometimes goes up at 2->3.

I plan to check vacuum.

Today, I saw the filter right above the vacuum pump. It had some black stuff. So I blew it with a compressed gas duster (the spray type duster available in computer hardware store). Now I see a cleaner metal mesh. The transmission shift became a little bit better.

I hope you don't start out in 1 then shift up into 2 and drive. Thats not good for your tranny. If thats not the case, did you see if you have overdrive ON?

I usually leave the tranny at D. It automatically starts from 1. Some earlier production of Mercedes W124 (E class) starts from 2, but mine does not do that. Mine has no overdrive switch.
