99 f250 7.3 ps

[dirter]

I have an older plain chip at 54 HP I recently had transmission break. Reman trans seems to have a prob, but rebuilder says to try clearing computer codes in case there is something that is causing the prob. I stopped in at a shop and they hooked up an actron code reader which showed no codes to clear. Will the chip mask some codes? Do you know if 7.3 requires special code reader?

Codes should appear properly with the tune installed.
