aod+more power?
 

A local tranny shop that i have done business with in the past tells me that if i add a new intake manifold and larger thottle body and bump the power,He says that the aod trans will not hold up.He says you have to raise the line presure,is this true?It's a '92 5.0.

The new intake and throttle body won't add much of any hp, so he's wrong about that causing problems. On the other hand, the AOD is known as a relatively weak tranny. The first major mods you should do to those cars is beef up the tranny so you won't be spending money down the road fixing them.

Sides, a converter, shift kit, and 4.10 gears will probably drop you nearly a second in your ET.

What sort of things can you do to beef up the tranny?
