Thanks to those who responed to my earlier post on the leaking transmission fluid on my 98 ML320. It is coming out of where those electrical wires go into tranny. I made an appointment at the shop to fix it. Tech told me about 3.5 hrs of labor to drain, replace o-rings on the inside & and outside and refill w/ tranny fluid. My question is, does this sound correct? This is not a dealer but a local indie. Closest dealer is 3hrs. The leak has quit for now I'm assuming the fluid has drained below the level of where the wires go in. Does anyone else believe they need to drain fluid or can they try and fix from the outside and top off the fluid. The fluid was just replaced w/in the last year so its new. Thanks for your thoughts.
