Is there any check engine light on? This car has a computer controlled rack on the injection pump I believe. If the computer finds something wrong, it might limit engine output. I've known of cars that will throw a code and limit power if the driver tries to downshift at too high of a speed. Otherwise, I don't think the transmission on that car would let you do that. As has been stated earlier, the 722.4 in my 300D 2.5T won't let me do it. I think these cars have the 722.5, the last hydraulic auto before the electronic 722.6 in 97.
