Shift Solenoid
Shift solenoids are small electronic valves that control the flow of transmission fluid and tell your automatic transmission when to change gears. When one fails, you may notice rough shifts, slipping, or your transmission getting stuck in one gear. We diagnose the fault, replace the bad solenoid, and make sure your gears shift smoothly again.

- Dirty or contaminated transmission fluid clogging the solenoid
- Electrical fault or broken wiring to the solenoid
- Normal wear of the solenoid over time and mileage
- Overheating of the transmission damaging internal parts
- Low transmission fluid affecting solenoid operation
Frequently asked questions
What happens when a shift solenoid goes bad?
You might feel harsh or delayed shifts, the transmission slipping, getting stuck in one gear, or a check engine light. A scan tool usually reveals a solenoid-related trouble code to confirm it.
Can a bad shift solenoid be fixed without replacing the whole transmission?
In most cases, yes. Solenoids are often replaceable on their own or as part of a solenoid pack, which is much cheaper than a full transmission rebuild. We'll confirm the exact cause first.
Is it safe to drive with a faulty shift solenoid?
It's better not to. Driving with erratic shifting can stress and overheat the transmission, leading to bigger and costlier damage. Have it checked as soon as you can.
