2001 Chrysler 300 Transmission

There's really no easy way too change your transmission fluid without a machine. What they do is a fluid exchange where the old remove is removed and new fluid added until 99% of the fluid is replaced. If you attempt to do it yourself you will have a hard time removing all the fluid in the lines. The transmission is very sensitive to fluid level so after the change check it when cold then when its hot. Most service centers can preform this service for 140$ and it takes about 20 min.
