Frequently asked questions
What is a shift solenoid?
Shift solenoids are electronic valves inside the automatic transmission that control the flow of hydraulic fluid. By opening and closing, they direct fluid to different clutch packs and bands, allowing the transmission to shift between gears.
Can I replace a shift solenoid myself?
Replacing a shift solenoid often requires dropping the transmission pan, which can be a messy job. It also requires specific knowledge of your transmission type and careful reassembly. While possible for an experienced DIYer, it's often best left to a professional.
