ok guys the other nite i drove my truck about 50 miles and got off the highway and went to the local jack in the box and as i was leaving the tranny was acting funny like it was slipping for about 5 seconds then it quit and drove fine all the way home and the next two days it has drove fine.....anyone have any ideas????? it just acted up like it was slipping for about 5 seconds or so!!!!!!!

 

YES...exact same thing happened to me a couple months ago. I ended up having to replace my tranny that hurt the wallet, ALOT! Mine first started doing that. then it would be fine for a few days, then eventually things got worse. Usually it happened after driving on the highway for a period of time. Near the end of my trannmission's life, it would completely throw itself out of gear, until one day, it just wouldn't go back in. I felt ashamed to be broken down on the side of the road in my Dodge. The only reason they make curbs is for Fords! My problem was a plugged up tranny cooler. Since the tranny wasn't being cooled, the inside welded itself all together which is needless to say, A BIG PROBLEM! I don't know if whats happening to your truck would be the same problem or not, just thought I'd share my bad experience.

 

mine did the same right before it puked. The dang check valve in the lower cooler line stuck shut. Hello rebuild.
