92 Mustang Auto (AODE?) Shifts into OD Early

[cjmatt]

Any idea what would cause this, car has lots of power in lower gears, but quickly gets into OD and becomes a turd. Is this a Throttle Valve setting or something?

you should have a lock out put on it for od... od is a weak gear and should not be used under a heavy load

1992 mustang AOD is non electronic. I would check the Adjustment of the throttle cable.

Several things, if you have a lower rear axle ratio, its going to go into 3rd and 4th at the same rpm, but a much lower mph. If the torqueconverter is a stock one, once a aod shifts into 3rd, it no longer has a fluid connection or any torque multiplication from the converter. The transmission becomes directly connected to the engine.
Proper tv adjustment and geometry are crucial. Most people do not realize when they take off the factory fuel injection and put on a aftermarket intake and Holley carb, they screw up how the TV cable is suppose to function, and the transmission never does shift correctly. The sell aftermarket brackets for Holley and eledrbrock carbs that correct this problem.

check the condition of the bushing on the Cable and throttle body. I have seen them wear out and cuase similar conditions.

Don't adjust the TV cable

with out a pressure gauge and the correct TV cable tool!! You'll be asking for trouble if you don't.. If you don't have them, you can borrow mine, just call.
