42re whines and doesn't go in gear or slips, only when warm.
My 02 grand cherokee is fine when it's cold but as it warms up it starts to whine from pan area in every gear but park. Then it starts to slip and not go into gear. Changed pan filter and fluid helped for about 30 miles. I was thinking trans pump or converter but it doesn't chatter like converters normally do so I'm not sure. Either way I'd like to figure it out before I pull the tranny and replace it.
