i got a huge problem my 700r4 is acting up checked fluid and its full. Recently changed filter and fluid. The wierd thing is that it can go into gear and shift when its under 170* after it gets hotter then that it wont even go into gear.. Anyone had this problem b4 what do you think is wrong thanks for the help.

 

just a WAG but since you said you changed fluid and filter not long ago are you sure you have the filter seated in the trans correctly? if not it'll fall out and not suck any fluid out of the pan into the trans.
