How to check transmission fluid in an ML350 - 1989 Mercedes-Benz 190

Mercedes. From the bottom. You have to fill it at the bottom also. Depends on you r transmission where and how to fill it. Some on the pan, some at the passenger side of the transmission. some you can fill from the top, but takes a dip stick and scanner to get correct.

code p 0845 refers to transmission fluid pressure (TFP) sensor B --circuit malfunction===causes --wiring---poor connection --- TFP sensor ECM/TCM
check all wiring and connections for corrosion
replace the TFP sensor

Sounds like it is low on transmission fluid. You can get a car checked out fairly cheap at an oil change shop. Then you can decide if it's necessary to go to a dealer or not.

The 99 C230 has a "dipstick tube" located in rear of engine close to the firewall accessible from passanger's side under hood. This tube should be covered by a black plastic top. Remove the top and insert a long piece of thin plastic-covered cable (very thin, like 1-2 mm) -- pull this cable back out as soon as you start to feel resistance. It should be wet with red transmission fluid. If it is brown, the fluid should be changed by a "QUALIFIED" technician who will use the correct fluid & procedures

If the transmission is slipping and I assume that is what you mean then it is going to need an overhaul. Once an auto transmission slips it is done.

brake fluid generally every 2 years, transmission not to sure usually 80-100k but should say in the logbook

yes Mercedes changed the transmission service interval to 40k miles but then after that you don't have to service the transmission until you reach 140k miles. It is a good idea to the transmission serviced at this mileage especially for warranty purposes. There was a lot of issues with the new 722.9 transmission when it first came out. Which is one of the reasons Mercedes moved up the transmission service from 100k miles to 40k miles for the first time it needs to be serviced anyways. Plus if the transmission happens to need repairing the first thing the dealership will look for is to see if the trans service had been done at 40k miles before doing any kind of warranty work on the vehicle. As a former Mercedes Benz Tech at the dealership I would say yes it is necessary to get the trans serviced.

check your brake fluid, if the brakes are wore that bad then the brake calibers extended out all the way which will use more brake fluid and trigger the sensor to warn you, or worst case you are leaking brake fluid somewhere.

Hi, The rear and the front washers both use the same resevior. I think the fluid level sensor is at fault.
