Does it take time for transmission fluid to work?
Mostly, the average time it takes to change the fluid in a transmission it 1 hour. However, because some of the newer vehicles are built differently, they don’t require a fluid change as often as older models, so be sure to read the owner’s manual or ask your mechanic for professional advice about transmission service.
What shifts the transmission?
The most common type of automatic transmission uses hydraulic power to shift gears. As the engine transmits power to the pump of the torque converter, the pump converts this power into transmission fluid that powers the turbine of the torque converter.
What to do when your transmission delays shifting into drive?
The first thing to do when you notice a delay is to check your transmission fluid. The fluid will tell you what kind of condition your transmission is in based on level, color, and smell. If the fluid is low, dark in color, or has a rancid smell, the vehicle should be taken to a service shop immediately.
Why is my transmission not working after 15 years?
Uncle Turbo is correct. If the fluid had not previously been changed in the car’s 15 year/130,000 mile history, then a “flush” could definitely cause a problem by circulating the crud that had built up in the transmission pan during those 15 years.
What causes a transmission to get delayed engagement?
Delayed engagement could be due to a variety of reasons from something as minor as a low level of transmission fluid, infrequent fluid replacement, or a more serious issue like failing transmission solenoids. Also called a “shift solenoid”, in automatic transmissions, the solenoid is used to regulate the flow of transmission fluid.
Why does the transmission not engage after a cold start?
Ever since then, whenever I do a cold engine start (the car having either sat overnight or having sat for several hours after I have driven it during the day) the transmission does not engage immediately after I shift the car into gear. I usually have to let the engine run for a minute or two before it will engage in reverse or drive.
