Rite my truck is 94 4.2 with A442f box. My missus cooked the old box and I bought a spare truck and took the box out of it. I did approx 150 miles in the truck before it came out and it drove fine. Christmas 2011 I swapped the box over and noticed something after a while. When taking off from a stand still it stays in 1st for a split second and then changes up into 2nd and causes it to be very slow getting away kickdown has no effect and it just stays in second. I have noticed that it doesn't do this when cold only when it warms up. I was off roading a while back and even in low range it was the same I really struggled to get up a hill to the point where I had to give it a rev and knock it into D this was the only way it would take off and stay in 1st. If I didn't do ths it would have just stopped on the hill and not even spun a wheel. I have tried manually putting it into L whilst driving and it doesn't go in all the time and if it does and you rev it hard it will change by itself even when still in L.
I have researched before posting. Kickdown cable adjustment is good. Oil has been changed and level is good. I have read about testing shift solenoids but got lost in tech talk I need the idiots guide! LOL
