93 LX FiveO

my mechanic replaced my C3W with an A9L out of a '92 5.0 HO with a 5 speed

i read somewhere you cant read codes with these in auto's=

he also said he tested it for codes and nothing came up

car runs good and strong, a little on the lean side as you can smell gas when sitting. transmission shifts quicker than it did before but i think my C3W was chipped for the AOD because i could hold any gear to any rpm.. cant do that anymore with the computer.

think the computer is the problem or my tranny just showing signs of 'needing replacement'?

You have the wrong computer. Take it back to the mechanic who did this to your car and tell him to fix it!

The correct computer will be either the same as what you pulled (C3W), or you could use an A9P.
I am not familiar with your car, but there may be some re-pinning needed to run the A9P.

Let us know how it goes.

its already in the car and it runs fine

from what i read through a google search, i wont be able to read some codes so i was just wondering if this is true?
