I can't imagine we don't have a sensor for low trany fluid.

I had a leak from the radiator pipe going to trany, it was leaking for almost a week and lost more than 2 liters of fluid and no check eng. or any code poped up.

luckily I found the leak before I damaged the trany.

It was the seal attached to the radiator and the cooling pipe going to the trany.

I never thought it was the trany fluid coz it was yellowish color and my eng. oil level was ok.

 

No sensor. The trans was originally marketed as "sealed for life".

 

I also read it was sealed for life and no service required, but why does the MB dealer suggest a transmission service every 60,000miles?

 

There is no such thing as "sealed for life" or "lifetime fluids" it's all BS. They tell you this, so when your tranny gives up the ghost, they make a ton of money fixing it. Your transmission needs servicing just like any other automatic transmission. I recommend having a full transmission service every 40K, including the torque converter and filter change. This is the guidance that, I received from my shop manager. BMW says this as well, to lower the cost of ownership. But when it's breaks, after the warranty is up, it didn't lower the cost of ownership, but increased it substantially $$$$. Trust me have a full tranny service done, and not a tranny flush. Transmission are expensive to replace in a AMG.

 

what are the services needed to be done for a 2003 e320 tranny?

 

at 60k drain and fill tranny and rear diff fluid.

 

what kind of fluids i should get? brands? specs?

 

you should be alright with the fluids MB dealership sells

 

What is the difference between a normal tranny service where you drain the fluid, change the filter and fill it back up and a full tranny service?

 

+1

 

A tranny flush is simply that a transmission fluid flush, undo the transmission and torque converter drain plug, empty and refill.

The transmissions fluid service is when we replace the transmission oil pan gasket, new o rings, filter, and the electrical connector.
About a $400 dollar service.

As for the fluid, you would want to use MB part # 001 989 68 03 10

 

Thanks James. I just assumed you would replace the filter and gasket so it's nothing fancy. That's pretty much what I had done at around 50k. I've heard of the pressurized, complete flushes where they flow clean fluid through the entire transmission but I avoided that after hearing some bad stories. Don't always have to reinvent the wheel.

 

Corret me if I am wrong, but the 722.xxx has only one drain plug to drain the fluid form the transmission casing, the fluid in the torque convertor cannot be drain. the only way to flush the tq convertor is to do a drain and refill a couple off time and cycle the car through all the gears.

 

I believe the 722.6 has two the 722.9 might only have one.

 

you have to pop your rig in neutral to get to the TC plug. bell housing has a few windows to look through from the bottom.
