4R70W no 1st 2nd or reverse
2006 f150
Was running fine until I got off the highway, then when I went to take off from the stop sign it was real sluggish, like it was in the wrong gear. O/D light flashing and transfault came up. Pulled the codes and got:
P0731 (Gear 1 incorrect ratio), P0732 (Gear 2 incorrect ratio)
The transmission make a clunk when you put it in reverse but it won't move, when I put I in drive you can hear a whining sound coming from underneath the truck. 3 rd and 4th gear work fine once you get up to speed
I have searched the internet for information and ended up replacing all the solonoids in the
bottom of the tranny, this has not fixed the problem. I have searched several forums but can't find anybody that's having the exact problem I am having
Any help would be appreciated
