after it warms up it wont shift even if you pull it as hard as you can it wont.you can turn it off and it will shift thru the gears but once it warms up it wont again any help???
Does this car have a manual transmission?

If it’s a stick shift, sounds like you have clutch problem. Check the clutch fluid first. It’s right next to the brake fluid…The hot and cold thing is a little strange…
