[aldeasal]

Hi everyone. im looking for someone to help me with this question. im looking to buy a set of 4 22" rims for my 04 expedition. i was told that i need to purchase a computer programmer so that i do not damage my tranny. is this true? can someone help me with this question. Do i need to reprogram the computer on my suv?

No, your speedometer might be a few mph off if you don't reprogram but it won't hurt your tranny.
