Need some advice
I have a '98 F150 I need to sell. It has a 4.6L and is 4WD.
The 4R70W transmission in it...is rough.
At first it would fail to shift 2-3 when cold, but as it warmed up it would go away. I figured it would be something bad in the valve body and would be an easy fix.
But then one day, it did a neutral drop out of second instead of just failing to shift.
I also wonder if it is slipping all the time as the truck only gets 14-15mpg max. (EDIT: I looked it up and apparently this looks like average MPG for this truck)
If a valve body problem could cause these symptoms I would be very fortunate.
The truck has been sitting for a long time, so I need to change all fluids. But if this trans is a lost cause, I don't want to burn the $100+ on a fluid change if I should put it towards a new transmission instead.
All Glory to God!
