Shift kits for the auto tranny? Tuner or something like a j-mod any help?

we did the transgo in doc's mach a week or so ago. great ki, if you looking for one thats the one i recommend. if you dont have a tuner, i recommend getting one first before a shift kit.

Ok correct me if i'm wrong...but isnt the j-mod already done on the 03-04 4r70w's?

A tuner will definatly firm up your shift...since im not putting big numbers to the ground, the tuner is about as far as im going to go.

All but 1 hole in the seperator plate is enlarged in the 4r70w in these cars. You will love the transgo kit. mine shifts perfect now. It comes with a good video and tells you exactly where everything goes. If you want some more detailed info about what you will get into when you do it, you can shoot me a PM. Gave me better shifts than the tuner did, but with the tuner it is nice and wicked.
