Worn out or old transmission fluid can lead to a hard shifting automatic transmission. The materials that make up the transmission are selected differently as they communicate with the transmission fluid, and if inappropriate materials and liquids mix up together, it can cause too much friction, leading to hard shifts.

It may also result in sloppy shifts and low friction. As time passes, more and more lubrication will start to get lost, and there may even be a reduction in friction modifying properties. The change in the previous scenarios will lead to a change in the transmission shifting, ultimately giving rise to the issues.

  • Low Fluid Levels

The fluid in the transmission gives hydraulic pressure to shift the bands and clutches that facilitate shifts. To avoid shifting problems, you have to prevent a low-pressure situation, and for that, you have to ascertain that there’s no low fluid level due to leakage or anything similar.
