please help my 2000 ram 1500 ext cab 5.9 v8
while going down an interstate in cruise, I engaged the coast button the transmission has not tried to pull since.
will not go into reverse or any forward gears.
can any one tell me where to start looking for the problem? transmission fluid looks as good as the day it was put in.

 

how many miles is on it

 

Maybe try disconecting the battery for a few minutes (to clear the computer) or pull the fuse for the cruise control and see if the problem goes away.
