Question 1

Why does my automatic transmission shift hard?

Accepted Answer

Common causes include low or burnt fluid, worn mounts, or failing solenoids. Check fluid first—dark or burnt-smelling fluid needs attention.

Question 2

Can dirty transmission fluid cause hard shifts?

Accepted Answer

Yes, contaminated fluid doesn't lubricate properly and can cause harsh shifts. A fluid and filter change may help.

Question 3

Is hard shifting normal when cold?

Accepted Answer

Slightly firmer shifts when cold are normal as fluid is thicker. Severe jerking or banging is not normal and should be checked.
