How to Tell If Your Automatic Transmission Has a Problem
The automatic transmission is one of the most expensive parts, so noticing early symptoms saves a lot. Most problems start with degraded or low transmission fluid.
Common symptoms
A delay in engaging drive when setting off, a jerk or hard shift between gears, slipping (the engine revs rise without matching acceleration), or strange noises. A check engine light may appear with a code like P0700.
The most common cause
Old, burnt, or low transmission fluid is the number one cause. High heat damages the transmission quickly, so proper cooling and fluid level matter a lot.
What to do
Check the level and color of the transmission fluid (it should be clear red, not brown and burnt), and keep to the change intervals in your manual. Read transmission codes via OBD2. Mowtar AI reminds you of the service time and explains transmission codes.
FAQ
A light jerk when shifting?
It can be normal on some models, but if it grows or comes with delay or slipping, check the transmission fluid first.
Should I change the transmission fluid or not?
Follow your manual; some transmissions are sealed, but most need periodic changes. Neglect is more dangerous than an on-time change.
