Hello all I have a problem with my aod.It has about 4000 miles on it 1,2 and 3rd works fine shifts into od fine when you give it gas it slips.truck has 3.50 gears and a 351w.

 

I didn't think the AOD was ever paired with the 351w in a truck. I thought they were all E4ODs. What year is the truck? F-150? What does the data tag in the driver's door opening show? There is a letter under TR that tells what transmission is in there.

 

Sorry about that its in a 1956 f-100

 

Slipping usually means it's rebuild time. If it hasn't slipped very much it MIGHT be still good.

An AOD will slip if the TV pressure isn't set right. I don't have the procedure to set it, but I know it's critical.
