Hey guys, i have an appointment with the dealer on monday. but this is my first time at this dealer. had lots of problems at the previous one. well i have an cai on my car. do you think that they would void my warranty because of this? im taking it in for a shuttering noise from the tranny, in the last dealer they changed the egr valve and said it was fixed, but the problem continued. dont wanna take it back to that dealer because i had it out with the master tech and the service manager. and my car is vibrating when shifting from 3rd to 4th gear. does anyone know what this is from??

 

If they can prove that the cai is the cause of your tranny issue then they can deny the warranty work.
