Does anyone know about my question?

 

yes... I have seen some post up on it before alex. I dont have an auto so i cant go into detail.

 

Won't mess up your trans. I've had my 52mm throttle bodies on too many cars to count with no programming (including my own) and have never had one even shift funny. The 58MM throttle body is a little bit different though.

i tried a buddies 58 bbk on my A4, his was an M6, but i used my TPS and IAC. it worked fine part throttle, but at WOT it would quickly shift into 3rd gear (even at 15mph) and threw a SES code.
i thought my tranny was toast again. i called Cmotorsports.com and they told me i had to have reprograming with an A4 (great customer service btw) well i put my stock TB back on and it works perfect????

they told me it had something to do with the TPS sensor needed reprogrammed in the pcm.
