My truck, a 2004 fx4 f150, is taking forever to go in gear but once it does it shifts through fine.. But when it goes to downshift it misses completely and just pretty much goes in neutral.. Anyone had this problem?? Just keeps getting worse.. Tranny finally threw a code yesterday of output speed sensor.. Could a sensor really be all it is?

Oops sorry wrong year thread lol

I would think that if it threw a code then that would be the culprit. Maybe the speed sensor is giving a false reading causing the computer to think the truck isnt moving or moving fast enough?

Id swap it out and see what happens.

mine is a '06 fx4. i have to rev engine to go into gear. it changes fine with no slipping. i got code p0720. output shaft speed sensor circuit. i haven't replaced yet. hope it fixes yours. let us know if it works.

No luck

Looks like your luck runs like mine. Did you try running for another error code after you got sensor replaced? Will be first of week when I put new sensor in.

Still haven't figured it out.. Talked to a few people and everyone is saying pressurization.. Working on it again now let you know if I find anything. If not I'm taking it somewhere monday
