- Mercedes Benz E Class AMG: How to check Transmission fluid
Step by step instructions for do-it-yourself repairs
checking/adding transmission fluid on E55
Look for a tube near the fire wall that has a tamper resistant cap May be hidden by the air filter housing. Factory caps are red
You have to break the cap to remove it so you will need a replacement, About $1.25 from parts houses
You will need a dipstick that does not come with the car.
They are available from M-B for a small fortune or on Ebay from China
I bought both the oil and tranny but I dont think you need both- one might do
As for the amount of oil showing on the stick- Probably have to do some digging on this board but I believe some one posted the amount that is coated in millimeters when full
Use only M-B OEM tranny fluid
As with any automatic- DO NOT OVERFILL
I replinished mine by removing as much as would drain from the sump, measured carefully and increased it by 5 oz for the oil that stuck to the pan, filter etc.
The M-B branded fluid comes in LITERS
I would not add more than a few ounces until you have a definite benchmark for "FULL"
Since you have a short history with the car it is possible to think that someone broke the tamper cap and failed to replace it. That might make it come off with little effort
The tranny cap when properly installed will NOT come off without destroying a plastic tab.
At least one person here has filled their engine with fluid or vice versa (tranny with oil) Neither is a good scenario. You probably figured out that M-B does really not really encourage owner service for this item.
The 7 speeds have no filler in the engine bay and have to be dealer serviced.
Search this forum. Somewhere there are several good pictures of a V-8 with arrows and text. Might be a pain but better than having it towed or destroyed by the wrong lubricant/ quantity
I would advise not getting in a hurry. A few ounces of fluid on the driveway will not yield near the failure that overfilling / wrong lube will
PS There are no dipsticks OEM for these cars. You can buy a "service" tool
But it is too long to leave in permanently
