Hello everyone, We are new to the cooper family.

We have 2002 Base that we couldn't pass up. We have discovered an issue with the transmission. Drive great until it warms up. when you come to a stop it will shutter and then try to go at a very slow speed no throttle response (maybe a couple miles an hour) after it rolls out about 20 feet the shutter goes away and you are off to the races. After doing much reading it is sounding like the valve body is the problem. My question is can I just replace the valve body?
