    Transmission does not change gears when car is cold, also it takes the gas pedal more throttle for it to respond.
    However, I turned off the car once and when I turned it back on the car started changing gears perfectly and the issue with the gas pedal was fixed. I notice this issue is more occurring when the car is cold. While driving I have to let go of the throttle so it ...

      I would not use any vehicle with any trans problem
      you could ruin it in a few miles of driving then have an
      expensive rebuild to do

      Could be the gas pedal repairs did not
      address the shifting issue & it wasn't road tested
      to confirm the problem your having,take it back

      Have it diagnosed to find an issue

      Another thing is that I went under the hood to connect my scanner, but the car doesn't have a pluggin for the one scanner but more of the light configuration which it shows how many times the lred light flashed to come up with a solution and the car flashed 6 red lights.

    Transmission doesn't shift proparely when the car is cold. Also the gas pedal gets harder to accelerate.
    However, after driving the car for a while , it starts changing gears on time and the gas pedal starts working correctly, not sure what the issue is.

      I also have been working on cars for about 40 years, but I do not have any personal experience with ever having to remove a front drive axle from an S550 or any other MB that I cn remember. Now, that being said I imagine I'd end up in the same exact predicament that you have right now. I can tell you for sure that removing this axle is no different than any other as it has to be "popped" to overcome the collapse of the retainer clip. A quick check on all data shows a two piece tool which you can google to get sticker shock. Tool # 221589043300 and tool # 602589003300 which is an impact puller with a slidehammer that is shaped specifically for the axle shaft inner housing I presume. I assume that you have tried all the usual methods that we both would do. Just want to say be careful of using a fulcrum and lever type removal method because the aluminum transmission housing could fracture with too much pressure applied in any one spot.

      Where the soda was spilled into is the transmission range sensor anytime a repair is given a repair estimate is always given, You should have the vehicle check from your mechanic

      you have to go to a trusted benz mechanic and hook your car to a diagnostic would be able to see if there are any other problems with your transmission or if there is no problem, the mechanic will be able to reset your car's computer. hopefully this would erase any problems.

      You'd better use a professional person Benz diagnostic tool, so relatively safe, of course, if you believe that you can solve the problem yourself, or consult a professional mechanic.MB SD Connect Compact 4 support reading out & erasing trouble code,reading the real-time data of sensor and actuator, coding and programming. Also support wireless diagnose, support K line,CAN BUS and UDS protocol, with multi-language.hope it is helpful to you.
