Are tranny mods a must when going FI? Im looking at a Vortech system.

 

Getcha a 4L80e, dont waste money on that 60e

 

Mostly depends on how much your right foot weighs.

 

Best bet to make 4L60 last. GM frt and rear 5 pinion planetaries, Superior products billet super servo for 2-4 band and cover, 4L60 kit, Trans-go zinc coated spacer plate, Sonnax boost valve for pump, sonnax TCC upgrade valve, Billet acculmulator pistons Sonnax #77987-01k and 77998-03k, Raybestos Z-pack 3-4 clutch, Beast sun shell or GM shell with bearing provision. Set up probably good for 600 Ft/lbs.
