One of the less common maintenance that are performed on a car is changing the fluid. Typically, you’ll to change the fluid every miles or so along with the in the transmission. In the 1990’s, there more than a few major manufacturers advertising that had developed transmissions that no fluid changes. The fluid was considered to be lifetime oil, that it never needed to be Over the years, it seems this may have been an ambitious claim.

Originally, specified that the 722.6 was “sealed for life.” This that Mercedes has not specified a change interval. However, it that Mercedes has changed the for life” recommendation gradually by more frequent service in model years.

There to be a couple different schools of when it comes to lifetime Some people have that you don’t want to the oil in the transmission because the increased of the new fluid can dislodge particles of inside the transmission, clogging the new in a matter of miles. Other will say that there are additives in the new fluid that are not with the transmission.

In this article, we will go the steps involved with out the old transmission fluid and adding new The first step is to jack the car up and it on jack stands. Please to our article on jacking up your car for info.

The transmission fluid level is three to four ounces or minus and it will not function Put back in the exact amount this will allow you to the fluid, and worst case; to a local independent MB shop to top off the level.

You’ll need to the fluid from both the pan and the torque converter. On the bottom of the housing, you’ll see a square On cars up to 1999, this allows you access to the bottom of the converter. The safe way to rotate the for torque converter drain access is by turning the 27mm on the harmonic balancer/crankshaft pulley. You have to remove the front shield/sound panel in order to the pulley nut from below. The is held in place with six 8mm Remove them and set the shield

Once drained, the 5mm drain plug from the converter and let it drain. Allow the and torque converter to drain for at 15 minutes. Make sure you have a large container on the to collect all the fluid. It also to wear a set of protective gloves and a roll of paper towels to clean up any spills.

Once all the fluid has drained the transmission and torque converter, the old sealing washers from the plugs and fit the new sealing washers the filter kit on the drain plugs. Now the plugs in both the transmission pan and converter. Tighten the torque oil drain plug to 14 NM = 124 inch Torque the transmission oil drain to 20 NM = 177 inch pounds.

Locate the clamps on the outside of the transmission pan. These are held in place by a 5mm Torx On the front right driver’s one of the clamps is also held in with an exhaust shield. the clamps and you will be able to the transmission pan. Usually, it just drop off the bottom of the In our case, it needed to be pried Once you remove the pan, see both the valve body for the as well as the filter. The old filter pulls out of the valve body. sure you have the drain pan as you pull the filter out. fluid will likely streaming out of both the filter and the hole on the valve body. a good idea to inspect the where it mounts and clean the surfaces with a clean, rag.
