4 Reasons your Subaru Won’t Go Into Gear (And How To Fix Them)

Engine problems are no fun, but, without the transmission, engine power isn’t getting to the wheels — which means a transmission problem is just as show-stopping as an issue with the engine. When you car won’t go into gear, here are a few tips to help you narrow down possible causes and hopefully get it fixed yourself. If you’re in need of transmission service or repair to get your car back into gear, trust the experts at Byers Airport Subaru! Our service techs are extensively trained at the factory to accurately diagnose and quickly repair whatever is ailing your vehicle’s transmission. Whether it’s a stick-shift or an automatic, these are four of the most common reasons why your car won’t go into gear.

#4 Automatic Transmission: Malfunctioning Shift Lock Release
To prevent the car from being accidentally put into gear without a driver present, modern cars with automatic transmissions will lock the shift knob in park until the driver’s foot is on the brake and the engine has been started. In some cases, the shift lock could get stuck and fail to disengage properly. On virtually all modern cars with automatic shifters, you’ll find a Shift Lock or Shift Lock Release switch located somewhere near the shifter. Often, it’s hidden under a small trim piece that you’ll need to remove with a small screwdriver or key. It’s operated by sticking the key in to release the lock. You’ll then be able to shift into drive.

#3 Manual Transmission: Failed Clutch Master Cylinder
In a stick-shift car, the master cylinder is responsible for translating the motion of the clutch pedal into motion that releases and engages the clutch itself in the transmission. The master cylinder operates using hydraulic fluid. Over time, the clutch master cylinder could spring a small leak. Once enough fluid has leaked out of the system, the clutch pedal will stop engaging the clutch and the car won’t go in gear. Another symptom of this problem is a clutch pedal that falls all the way to the floor. To address this issue, you’ll want to have a professional technician replace your clutch master cylinder.

#2 Automatic Transmission: Bad Automatic Transmission Fluid
A modern automatic transmission operates on the principle of fluid dynamics. Over time, the transmission fluid will thin out, become dirty and require replacement — otherwise the car might struggle to go into gear. You might also experience rough shifts or the car might require multiple attempts to go into reverse or go from reverse into drive. That’s why it’s important to have clean automatic transmission fluid in your car, and have it replaced according to the recommendation in your owner’s manual.

#1 Any Transmission: Severed Linkage Wire
Of course, if the shift knob in the cabin can’t actually “talk to” the transmission located underneath the car, it’s not going to be able to go into gear. While an uncommon problem, cables and wires can occasionally be severed over time by rubbing against sharp metal edges on the frame of the car. If the linkage cable to your clutch or transmission is pinched off or severed, you won’t be able to get your car into gear — regardless of what you do or what kind of transmission your ride is equipped with.

If you’ve exhausted all your other options, and you suspect a severed linkage cable, you’ll want to have a trained technician take a closer look. Locating the source of this problem can be especially tricky, and require advanced tools most amateur mechanics and do-it-yourselfers won’t have access to.
