Hi Diego.
1954 is the starting point in creating the new range of trucks by Mercedes-Benz. Everything started with light upgrade and rename of the previous series. The L3500 and L4500 models have received three-digit numeric codes - L311 and L312, which indicated the type of installed engine. The design of trucks has not changed (externally can be distinguished only by windscreen wipers, installed from below, not from above as on the previous version). There was also a four-wheel drive LA version. In 1954, a 4.6-liter diesel engine, installed on fire chassis "L311F", has received a turbocharger for the first time, which increased power from 100 to 115 hp. Totally about 175 thousand trucks of L311/L312 models have been made.

this is trans. mount..there are about 5 different motor mounts....

As its all your windows, the best bet is to check your fuse box. At a guess the fuse which serves the window motors has blown.

Diesel shouldn't damage the engine but likely fuel pump (electric) might be damaged, Diesel is lubricous but any and all fuel filtering devices shouuld be replaced. Good luck

Dextron Mercon, Napa sells their own brand, you can purchase the type that is for higher mileage trans., works well for me on my 95 300D.

Hello, Diesel Hi-test made by lubra-moly is a great additive for diesels but usually only found at some of your Mercedes diesel repair stations. Lucas also makes some good products.

If you find this information to be correct would you please enter a "fixya" rating.
Thanks, Gator241

no this will not improve the performance of your diesel, the glow plugs are used to ignite the fuel at initial start up and then they turn off.
