roundboy, yes you need 3 shift levers. I am sure there is a difference and it has been many years since I ran a Guss but I didn't see a noticeable..."this car is so much faster with this Guss"...difference. Bert/Brinn/Falcon are much stronger, the input shafts as well as the cases, are a weak point on the Guss. I believe we ran Ford ATF.
