I have a 1999 Ford Ranger XLT with a v6. The truck is shifting fine but when you slam on the gas the light will start to flash on and off. once i turn the truck off then on it goes away. Some people say a sensor in the rear end? could it be some type of senor?
Or What could cause this to happen?

Thanks

 

mine is doing the same thing, i went out and bought an obd2 today and it never picked up anything, let me no if u ever find anything and i will do the same for you

 

have you checked your fluid level and the color of it. When mine flashed i ended up writing out a $2650.00 Check

 

My blood is not as red as my tranny fluid is lol, I don't even notice anything wrong with the truck it just keeps flashing

 

so i re scanned my computer and i was doing it wrong first i did find errors it says i have incorrect gear ratios

 

i honestly think the problem might be the speed sensor considering i don't notice bad shifting when i am accelerating slowly, the other thing i noticed on the obd2 is the they are not manufacturers codes and there cow;d be 100 different reasons to why it is giving me that error i'm going to call ford tomorrow and sees if i can get a speed sensor ill reply if it works
