My Ram ever so often will act like it's almost in neutral at take off from a stop. It transitions smoothly but it's really slow until about 25 mph then it goes just fine until I stop or slow down to a bout 5 mph. Most times it will stop this behavior if I stop , shut the engine off and restart it, sometimes I have to do restart it a couple times. Someone told me it sounds like trans filter is bad. It gets worse the warmer the weather. Figured I'd ask for thoughts here.
