Transmission will not go into gear, cash prize to whoever helps me solve the problem!

[handlebarstar]

Hello, first post on the forum but I have been lurking for the last 6 months or so. My truck is currently out of commission and I'm hoping someone here can help me diagnose and fix it. about a week ago I went to put my truck(2004 FX4 Auto Crewcab) into gear and it was like the truck was in neutral. I had driven the truck just a few hours earlier and it drove completely fine. Now it wouldn't work in D,1,2,3 or Reverse. So far I have pulled codes P0720 and P0722. I have replaced the OSS sensor as well. If I rev the truck up to about 2k rpms and leave it there for a second it will creep forward in Drive and will chirp the tires going into reverse. Other times when I put it in reverse I can floor it but the truck won't rev up at all. The towhaul light flashes sometimes after messing with it for a while as well. Has anybody had this issue? Any help would be more than appreciated!

Thanks

Sounds like a stuck valve inside of the trans. Check your fluid for color/smell/consistency and if bad, change it and the two filters.

Otherwise, it's time for a trans repair.

Thanks for the info, the fluid looks and smells ok. I was hoping it was a simple electrical problem but I think it may be internal now(even tried a new pcm to verify). Looks like it's getting towed to the dealership

call around to a few local transmission places and see what they say. They should be a ton less than a stealer****.

Sounds like the dealership is going to get the cash prize.

Good luck man!

Iam also having the same problem. Had it towed to the dealership thinking it was the transmission. They said I had 4 bad injectors that I was only using half the engine. Also said that the engine could of had an effect of the shifting solenoid at least that's what I hope.

Did the pick-up fall off into the pan? I had this happen in my A4OD.
