I often wonder why people keep saying that you should put ATF in that manual transmission, it makes no sense. Won't it even affect transmission performance? I never had problems with my manual until I tried ATF!!
Recently, I couldnt even downshift from 4 th gear to 3 rd Gear.
Perhaps I have a damaged Synchro, but before i tear down the transmission, i would like to put Gear Oil in it and try it..

Per Mercedes, the manual transmission in your 83 240D MANUAL transmission uses AUTOMATIC transmission fluid.

A moron independent mechanic put gear oil in my 82 240D manny tranny during a fluid change. I couldn't shift it at all when the temp was below 50.

MB states to use ATF. Your 240D had ATF in it for most of its life (until you or someone else put gear oil in).

Won't hurt to try gear oil, but I can't see how it would do any good.
