What happens to my Jeep in cold weather?
Everything works well except that the automatic transmission sticks in cold weather (50 degrees or colder). I have to drive the car 2 or 3 miles before it will shift into a higher gear. It gets really bad in 30 degree weather or cooler. I’ve taken it to a Jeep dealership and local mechanic.
Why does my Trans stop working in cold weather?
I doubt very highly that you are looking at a valve body issue. 90% of the time cold weather issues are because of the rubber clutch piston seals. With age, these seals harden and allow ATF to pass by them instead of retaining the fluid behind the piston. As the trans warms up, the seals soften and will seal.
What kind of shift does a car make when it sticks?
As for when it sticks, it’s definitely the 1-2 shift and somewhat the 2-3 shift. The engine will make a “whirrring” sound and stick at 25/30 mph. If I keep hitting the gas, the RPMs go high. Once I get through the 1-2 shift, the 2-3 shift isn’t too bad.
What causes a transmission to shift hard in cold weather?
Cold weather can lead to a transmission that shifts hard When the temperature drops, transmission fluids with poor cold-flow properties can thicken and cause elongated and hard shifts until the fluid has warmed up enough to flow properly. Switching to a high-quality synthetic transmission fluid will help.
What to do when your transmission shifts hard?
You can opt for a transmission flush or pan drop. It’s best practice to change the fluid before the frictional properties are depleted and you experience poor shifting. Those poor shifts can cause the clutches to wear more rapidly and lead to bigger issues that need mechanical repairs.
What causes a transmission to shift hard AMSOIL?
Common Fixes for a Transmission that Shifts Hard 1 • Low fluid level 2 • Depleted fluid frictional properties 3 • Poor cold-temperature fluidity More
What causes a clutch to shift hard in a car?
The fluid’s frictional properties play a vital role in ensuring the clutch plates bind together properly and gear shifts occur seamlessly. Over time, the fluid’s frictional properties can degrade, leading to hard, jerky or inconsistent shifts. In this case, it’s time for a fluid change.
