It only does this when cold i've had truck 5 yrs. never done this before.
when it's cold I put it in gear and it wont catch and when it does it jerks hard on 2004 Ford Ranger
Check the fluid level first. If it is full of fluid, take it to a repair shop for further testing. Suggest leaving it so the mechanic can see what it's doing first hand while cold. If fluid level is low, add fluid as needed. See owners for more information.
