My 1990 Ford F150 is jealous of my new girlfriend. Every time I go to visit her, and she only lives 1/2 mile away, my automatic transmission will not shift up as I accelerate. The engine is literally screaming before it will shift, like it does not want to drive to her house. Every other place I drive to, it shifts normally. There are no hills, valleys, half frozen lakes, or piles of broken down MG’s in between our houses. I think I may be losing my mind, please help. What might be causing this???!!! ---

Is it possible that the truck isn’t warmed up when you only drive ? mile down the road, and the transmission doesn’t like to shift when cold? Have the fluid and filter been changed regularly? ---

Is the fluid low? ---

It has been quite cold lately, although I do let it warm up for a couple of minutes. And sometimes after I’ve been driving for a while, it will get better, and then worse again. Fluid level is fine also. ---

Transmission may be too full of fluid. If you have a modulator valve, remove it and avoid the excess fluid that will be in a hurry to get out. I had that problem and it fixed it. Try upshifting manually and see what happens. A good girlfriend would buy you a new truck. Try hanging out in Palm Beach. ---

Well, having the engine scream with the possibility of it becoming shrapnel is definitely not the answer. My memory is a bit fuzzy on this but I think this truck uses a transmission kickdown cable that is attached to the throttle body. If this cable is out of adjustment for whatever reason the transmission can act like this. It can also kill a transmission pretty quickly and a screaming engine does not help the situation either.
