Hi everyone,
Been a lurker forever; have a 2007 ML320CDI that I've owned for 3-4 years (acquired ~80K) and now up to 205K. Took it in to dealership a few weeks ago for two minor items (alignment and belt tensioner replacement - it was getting loud for a few weeks). Long story short then noticed my Fan on HIGH after picking up the vehicle (it has been a very cold winter in Michigan and with belt tensioner squeaking I didn't notice). After diagnosis, said bad reading on transmission, lets do a transmission fluid change then drive it, but might need a transmission replacement.
Long story short, took 3 day weekend and a 600 mile road trip. Drive down vehicle worked without any issues, upon starting home today, entire time I could not do more than 10-20% throttle to accelerate, anything else it would not accelerate at all and only maintain speed. Let's just say merging on interstates at 35-40 MPH isn't fun (takes about a minute to hit 75). Within 10 miles of my house, I took the following YouTube Video of me giving the throttle 50%, 100% and a kick down full (all without lifting off the throttle); as you can see the vehicle does not speed up at all. I'm 90% sure I'm buying a new transmission, but figured to see if ANYONE else has experienced this same issue and it was something else?
