Q: Q: Shifting problem?

asked by on

my car wont accelerate of shift up past 45 miles an hour. the engine light is on and it reads 1st and 3rd shift cylinoid.

My car has 144000 miles.
My car has an automatic transmission.

Hi There, As you know, automatic transmissions use pressurized hydraulic fluid to change gears. Every time a gear change is required, the car’s computer activates a transmission solenoid, which directs transmission fluid into the valve body to engage the correct gear. When this is faulty or not working properly, this can cause a delay in gear shifting or in some cases cause the car to not shift at all. This type of problem is amplified any time the transmission is low on fluid creating a drop in hydraulic pressure. I would recommend having a professional from YourMechanic come to your location to diagnose and inspect your vehicle.
