Automatic Transmission Wont Go Into Gear When Cold

Question

Answer

Why does my transmission not shift when cold?

The cold weather can cause your transmission system to have a low line pressure by freezing and leaking fluid from the transmission seals. When a transmission has a low line pressure it can mean multiple things such as inadequate fluid within the system, slipping transmission, and improper function of gears.

What causes an automatic transmission to not go into gear?

Transmission won’t engage or stay in gear If when you put your vehicle into gear and it won’t move, this may be a problem with low transmission fluid due to a leak, the shifter, shifter cable, or it could even be a problem in the valve body of your automatic transmission.

Does cold weather affect automatic transmission?

Shifting Is Harder in Cold Weather Icy temperatures can also make shifting difficult for your automatic transmission. You might notice hard shifts or even delays in shifting. Cold weather also delays your transmission’s overdrive. This combination can damage your transmission if you push it.

How do I warm up my transmission before driving?

Start the engine, allow it to stabilize and idle for perhaps 15 seconds, shift into gear, wait a few seconds for the transmission to fully engage then drive the vehicle up to temperature gently.

How do you warm up transmission fluid?

So, when it’s extremely cold outside, start the engine, and let it idle for a minute or so before putting it in gear or under load. This allows engine oil and transmission fluid to circulate and lubricate. Then shift into gear and let the engine and transmission warm another 30 to 60 seconds.

How do you fix a car that won’t go into gear?

Press the Clutch Pedal Down More If you have a manual transmission, try to press the clutch pedal all the way down to the floor before trying to change gears. As the friction disc down, you have to press the pedal further and further down to move it away from the flywheel.

Why will my transmission not shift?

One main reason why the automatic transmission in your car may not be shifting smoothly is the ECM is going bad. It is best to get this checked out by an experienced auto mechanic technician who understands the electrical system. Other indicators include bad connections within, or worn out sensors and faulty solenoids.

Will an automatic transmission warm up in Park?

You are absolutely correct in park or neutral your converter has no resistance therefore you will rely on the engine to heat up the coolant. Putting it in drive even at idle will heat the vehicle faster in a Mazda 3 or a huge Cat front end loader because the transmission cooler is stacked to the radiator.

Can a transmission be too cold?

The ideal temperature for your transmission fluid is 175 degrees, plus or minus 25 degrees, however, when your transmission gets below zero degrees, it gets too thick. In this condition, it won’t be able to properly lubricate the internal parts, wearing the transmissions internal parts.

Does idling warm up transmission?

When your engine is running at idle speeds, it isn’t cooling as efficiently as it should be, and your transmission fluid is circulating slowly. As a result, your fluid retains more heat, and your transmission isn’t lubricating as effectively as it should be.
