Why does my transmission shift hard when cold?

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.

Is it normal for transmission to shift hard when cold?

Shifting problems: When it’s cold, the transmission will shift harder and shift points can become delayed which can lead to yet harder shifting. These hard shifts can create increased pressure on numerous parts which increase the risk of failure at a later point.

What causes an automatic transmission to shift hard?

Transmission Fluid Low or Poor Condition – Vehicles low on transmission fluid or that are operating with worn out or contaminated fluid are likely to experience hard shift conditions. Lack of adequate lubrication within the transmission can cause several problems, including hard shifting.

How do I make my transmission shift smoother?

There are 6 ways to improve automatic transmission performance and reliability. These are servicing the transmission, changing driving habits, driving with lower gears when loaded, maintaining engine performance, having proper alignment of tires, and having the correct tire size.

Can cold weather affect transmission?

Cold weather can wreak havoc on your vehicle’s transmission system leading to transmission slipping. In sub-temperature conditions, your vehicle’s temperature freezes, forcing it to contract, and your line fluids may begin to leak from the seals, leading to low line pressure.

What are the signs of a bad shift solenoid?

If you’re experiencing transmission solenoid troubles, it will become evident in one of four ways:

  • Delayed gear shifting.
  • You can’t downshift, and your engine continues to rev even when applying the brakes.
  • Your transmission gets stuck in neutral.
  • Shifting gears become rough and choppy.

Can too much transmission fluid cause hard shifting?

Transmission Fluid Leakage: Adding too much fluid will cause high pressure inside of your transmission. … These gears will have a difficult time-shifting making it more difficult to drive. Reduced Fluid Lubrication: Since the system will foam up, this will affect the ability to lubricate the transmission parts.

Will a transmission flush fix hard shifting?

If you catch a shifting issue very early, a transmission fluid flush can sometimes fix shifting issues. The fresh fluid helps clutch discs and steel discs bond and hold without slipping. The seal conditioners in the new fluid help soften the clutch piston lip seals so they seal better.

Will changing transmission fluid help hard shifting?

Moreover, some automatic transmissions have filters that should be cleaned or replaced when the fluid is changed. … However, fresh fluid is not a cure for gears slipping, rough shifting or other mechanical problems, so don’t expect a fluid change to be a magic elixir.

Why does my car jerk when I shift into drive?

In most cases when the car lunges or jerks when you shift into gear, it’s due to mechanical gears not properly aligning or components in the driveline system (such as driveshaft, input and output shafts) being loose or worn out.

Will a bad TPS affect shifting?

The Throttle Position sensor measures the throttle position, which is controlled by the gas pedal. It is used to determine engine load and if it fails it can cause automatic transmission shifting problems.
