​Common Transmission Failure Symptoms...
​​
1. Slipping Gears
-
The engine revs but the vehicle doesn’t accelerate normally.
-
Transmission unexpectedly changes gears.
-
Loss of power when accelerating.
2. Delayed or Rough Shifting
-
Hesitation or delay when shifting from park to drive or reverse.
-
Hard or jerky shifts between gears.
3. Unusual Noises
-
Grinding, whining, humming, or clunking noises when the vehicle is in gear.
-
Noises may increase with speed or when shifting.
4. Transmission Fluid Leaks
-
Red or brown fluid puddles under the vehicle.
-
Low fluid levels can lead to overheating and failure.
5. Warning Lights
-
“Check Engine” or specific transmission warning lights on the dashboard.
-
Trouble codes stored in the vehicle’s onboard computer.
6. Burning Smell
-
Overheated transmission fluid may emit a burnt odor.
-
Can indicate fluid breakdown or component wear.
7. Lack of Response
-
No movement when in gear (especially “Drive” or “Reverse”).
-
Delayed engagement when shifting.
8. Grinding or Shaking
-
Especially in manual transmissions, but can occur in automatics.
-
May indicate worn clutches or internal damage.
9. Noisy Neutral
-
Strange noises when the vehicle is in neutral can signal internal wear.
10. Vehicle Won’t Go into Gear

Either fully or with difficulty, often due to low fluid or internal component failure.
If you experience any of these symptoms, it's wise to have the vehicle diagnosed by a qualified mechanic as soon as possible. Prolonged driving with a failing transmission can lead to more severe damage and higher repair costs.
