everytime i drive my car.. the car jerks when it shifts from 2nd to 3rd.. it continues doing this until the temp needle is about halfway b/w cold and hot.. then it stops and runs smoothly again .. does anyone have any ideas?

either you need to flush the trans and put in a new filter or check your trans cooler lines and make sure they are not kinked or clogged.

 

Also check for leaks on the trans. Make sure the fluid is at the proper level.

 

are you sure the car is not miss-firing?
