Feels like transmission slips when down shifting?

Hello,

This issue could be due to a number of reasons.
The first thing you want to check is the transmission fluid level. Make sure it is at the correct level and in good condition. Contaminated fluid can trigger shifting issues.

This issue could also be due to faulty shift solenoid or worn internal component.
