I have a 1994 automatic F150 5.0 4x4 with dual tanks and I have been having trouble with reverse. Occasionally I will shift into reverse and the engine will start to putter and if I don't press the gas pedal it will stall out. Its almost like trying to drive a stick shift. It doenst do it every time but probably 60% of the time it will do that. I heard maybe it could be the transmission filter? Maybe idle air control? Any answers will be wonderful.

 

Low trans fluid is the most common cause of this.

 

The transmission fluid is full..

Update: I cleaned iac valve which was very dirty, started her up and I can tell it runs smoother and doesn't stall in reverse anymore. Except when I shift to reverse it seems to kick into gear hard.. I don't know if this matters but what do y'all think?

 

I found that I am idling at 1500 rpms. That is why I am shifting hard. How do I tune that down?

 

Usually by replacing the IAC.

 

Hey Jonathan did you ever solve this???

My truck is stalling when put in reverse.

Helppp
