Why is my automatic transmission not working cold?
Cold Automatic Transmission Issues. If you have a bad engine temp sensor, or a thermostat that is stuck open cold, it will provide a simulated cold operation value to the ECU and Trans telling it to continue to delay shift points. There are still many other reasons for cold shift issues, but the above are common reasons for cold failures.
Why does my transmission slip when the engine gets hot?
It isn’t when the engine gets hot, it is when the transmission fluid gets hot that the slipping starts, due to wear of the clutches and gears inside the transmission. First, check the fluid level to make sure it is full. If it is low, bring fluid level to full and see if that helps.
What to do when your transmission starts slipping?
First, check the fluid level to make sure it is full. If it is low, bring fluid level to full and see if that helps. About all the owner can do with slipping automatics is trying a transmission fluid and filter change to see if transmission revives and stops slipping.
How does a cold transmission work in a car?
Most newer transmissions rely on a engine temperature sensor input to determine the proper shift points of the trans during cold operations. Commonly, shift points and are delayed as well as overdrive disabled until the trans reaches full operating temperature.

What causes transmission to slip in cold weather?
Speaking of common transmission problems in a vehicle, like broken gears and bands, fluids of a poor quality, and so on, automatic transmission problems in cold weather is very common. This condition is also called transmission slipping.
Why is my automatic transmission slipping while driving?
Why Is My Automatic Transmission Slipping? If you have an automatic transmission and it “slips” while you are driving it—that is, the car engine revs without the power going to the wheels—the most common cause (though not the only possible cause) is low transmission fluid.
What to do when transmission slips after engine warms up?
If the tranny is just starting to slip then you could install a transmission cooler and this may preserve the life that is left in the tranny. As you were told it slips when the fluid gets hot, once because it gets thinner. By lowering the temp 20 to 50 degrees this can help. You can’t post conmments that contain an email address.

What causes an automatic transmission to not go into reverse?
In an automatic transmission, these units function as a one-way clutch. When the clutches begin to fail, the lower gears will not engage. Repair requires replacing the torque convertor and flushing the transmission fluid. A worn reverse gear can also occur when a transmission is mishandled.
What to do when your transmission is stuck in limp mode?
The majority of the time, the problem is not as grave as you may think. If your transmission is stuck in gear and you are far away from home, try this: Pull over and turn the car off. Remove the key. Do not press the gas pedal or any other buttons on the car. Wait 20 seconds. Start the car and drive to see if it is out of limp mode.
Why does the transmission not engage after a cold start?
Ever since then, whenever I do a cold engine start (the car having either sat overnight or having sat for several hours after I have driven it during the day) the transmission does not engage immediately after I shift the car into gear. I usually have to let the engine run for a minute or two before it will engage in reverse or drive.
Why is my transmission not working after 15 years?
Uncle Turbo is correct. If the fluid had not previously been changed in the car’s 15 year/130,000 mile history, then a “flush” could definitely cause a problem by circulating the crud that had built up in the transmission pan during those 15 years.
Can a Mercedes-Benz have a transmission failure?
Very few Mercedes-Benz cars have had complete transmission failure and require transmission replacement. We see these transmission fail in rare cases when water enters the transmission via the oil cooling lines or the radiator on cars equipped with Valeo radiators.

Why is my transmission slow when shifting into drive?
It’s a type of slip where the clutches, used to make the vehicle move, become slow and unresponsive. Pretty much every component on a vehicle is meant to respond instantly to do what the driver desires, including the transmission.
