What causes delayed shifting in an automatic transmission?

Delayed shifting is often caused by valves sticking the valve body, which prevents shifts from happening when they should. On newer cars, which control shifts using a computer, the problem could lie in the shift solenoids that are used to trigger shifts.

What will a dirty transmission filter cause?

When the transmission fluid isn't clean or is blocked by a clogged filter, the internal components won't have the lubrication they require to function properly. This could lead to shifting issues, grinding gears, slipping transmission or other common symptoms of transmission problems.
