Q: Should I change my transmission fluid?

asked by on

My mazda have a little dark transmission fluid. When i step on the gas all the way down very fast it takes a few second to shift and you can see how the rpm going up while the car is with the same acceleration. Someone told me if i change my transmission fluid it can be worst. Should i change my transmission fluid? Thanks

My car has an automatic transmission.

This may be a sign of low transmission fluid or a faulty transmission control solenoid. 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. I would recommend having an expert from YourMechanic come to your location to take the car for a test drive to more specifically determine the cause for this shifting issue.

Without some additional symptoms, this is hard to say. If the car runs smoothly when warm, this would reflect a "cold start" problem with the engine. If the transmission shifts harshly either cold or hot, the transmission may need repair...
