Q. I have and automatic transmission and wishing it was a 5 spd, but in the time being this is all i got.But If i get a shift kit in my transmission will it bark second? I have K&N performance air intake kit, and a hypertech programmer. so i wasnt sure if i need a tune up or what.

Q. I have a vibration in my truck ever since i got it but now that i am going to make it my Performance vehicle i need to know wth is up. whenever i go 80+ I get a loud vibration. But the funny think is whenever i let off the gas it completely stops.

Replies would be sweet and help would be to.  

about the shift kit, my cousin has been in the tranny business for 30 years and currently owns a shop building off road race trannies. he said that there are expensive shift kits and cheap ones, and there is no difference except the price. the one he put in my 66 mustang shift hard and would break the tires loose, he got the kit for $8.
