gears and hold switch
 

I was driving my mazda verisa 2007 automatic I bumped into a pavement and cracked gear oil strainer/filters and the hold light and engine check light come out. I took it to the garage and replace the clacked strainer but the hold and engine light is not going off.
I tried to drive it but it seems it is not changing gears fast it is taking time
what should I do

Take it back to the garage for them to diagnose & fix. Most likely a faulty or damaged solenoid.
