3 Speed To Turbo 400?

What is involved in changing from a 3 spd to a turbo 400? Can the brake petal still be used? The cross member has to be changed, any advice on doing this? Thanks

Re: 3 Speed To Turbo 400?

Are you going to use a floor shifter for it...or did you want it on the column as this will affect your steering column. Your old linkages are no good for the auto so you'd need all that too. Best to get what you need off a truck that has auto.

I have a TH400, if I was going to do a swap from a manual, I'd go for a TH350 or 700R4. The 400's have a rep for taking more hp to run...
