so after putting a new tranny in the truck i have been making my way around the truck just fixing odds and ends getting ready for a busy summer, pulled the line off to see if it was plugged, it was almost totally blocked! i just got some tranny rubber line and a couple of clamps and deleted that sucker before it could cause me any grief! i advise everyone to check the one on their own truck if they have not already! you could be saving yourself big bucks!
