Seal gone! Remove driveshaft pull seal out, check shaft for damage/wear. Refit new seal and rebuild
Replace the front seal which is located by the spline.
Check your transmission fluid levels. Look around for leaks...you'll see a reddish fluid around the drive axle on your transmission or around the radiator.
on the ground, if it tranny leaks
You replace the radiator
The fluid level in a transmission will not change unless it leaks.
If it is an ML W163 then it is Transmission fluid, same problem on mine...need to replace the O Rings on the plug to the transmission which can only be bought with the plug.....$10 here in Australia....common fault...my left shoes are all ruined on a right hand drive car i.e. where the footrest is the oil leaks & saturates the carpet
sounds like automatic transmission fluid
Some have an internal transmission cooler & extra small internal radiator for that purpose.
not always, but most times, yes. it will ruin the trans fluid pump.
You can't it is a sealed transmission. If you have no leaks then all if fine.
The transmission needs fluid to propel the car. If there's no fluid, you're going nowhere. Fill it up, and find the source of the leak. It could be a transmission seal, or maybe it's as simple as a damaged line from the rad. Don't try to move the vehicle at all until the transmission is full of fluid. You could burn out the transmission, causing a very costly repair.
I am having the same problem with my transmission. What holes are you talking about and where are they located? Mine leaks all the time, I have tried new gaskets and sealants but it still leaks. It runs great, but I have to keep the oil topped off every couple of weeks. I think it is a A727 tranny. Very tough.
