Can the cold weather affect a transmission?
Cold weather causes the parts of the transmission to contract and sometimes the gears can freeze which leads to slipping. Cold temperatures cause the fluid to thicken which means it can’t move around as freely to do its job.
Can a Mercedes-Benz transmission not go into gear?
Mercedes will start, but transmission won’t go into gear. Shifter can not be returned to Park (P), and you can’t remove the key from ignition. P,N,R,D gear selection indicator on dashboard not displaying correct gear. Mercedes-Benz cars that are equipped with automatic transmission have a gear selector shifter interlock safety feature.
What to do if your car gears turn weak in cold weather?
After the car is warmed up correctly in a few miles, the gears start to function normally. The battery of the car is the main component, if it happens to dry out, freeze, or turn weak in cold weather, obviously your car is in a big fix. All you can do here is either clean the terminals well or jump-start your car using a new battery.
What causes a car to have transmission problems in cold weather?
Transmission Problems in Cold Weather. A car having transmission problems in cold weather is a very common issue. The main reason behind it is, that the low temperatures increase the viscosity of the transmission fluid and it doesn’t flow smoothly in the system.
Where are the transmission codes stored in a Mercedes?
Specific codes related to the transmission are stored in the TCU (Transmission Control Unit) and come generic codes such as P0705 are stored in ECU (Engine Control Unit). You don’t need to pay anyone to read the codes; you can retrieve them yourself in a couple of minutes with the right OBD II scanner.

How are gears managed in a modern car?
Today every modern car has an automatic system, the gears in the vehicle are managed by the vehicle itself, whereas, older cars had manual systems installed in them, which always needed the driver’s attention while changing the gears.
Do transmissions need to warm up?
There really isn’t a reason to warm it up, unless you are in extreme sub-zero temps. Letting the engine idle for a couple minutes should do the trick (that is even a hot debate). If you are experiencing trouble shifting when the trans is cold, it could be an indication of upcoming issues, so get it checked out.
What affects transmission temperature?
The most common causes of overheating include solenoid problems, fluid leaks, low fluid levels and burnt/old fluid. Other heat generating factors are if you live in a hot climate, often drive in stop and go traffic and/or tow heavy loads with your vehicle.
Why do I have transmission problems in cold weather?

What kind of transmission fluid should I use in cold weather?
Use synthetic transmission fluid: Synthetic fluids behave much better and retain their given specs under cold weather conditions. Be sure to find the synthetic fluid designed for your vehicle.
What happens to the gears in a car in cold weather?
If the car hasn’t been warmed up for a adequate amount of time, it can take a while to start. The vehicle does not shift gears quickly because they are stuck due to cold temperatures outside. After the vehicle is warmed up correctly, usually after a few miles, the gears will begin to function normally.
What happens to a transmission when it freezes?
When it freezes, it expands, and that can cause damage to the case and valve body in the transmission by creating cracks. If those cracks appear, the transmission cannot be rebuilt. This issue tends to be a major problem on certain Nissan vehicles holding an RE5 transmission.
