I'm a hot rod kind of guy, and when i want to run my 64-259 Auto thru
the gears to see what she'll do, I take off in L and run it up till its
time to shift into second, shift to drive and let it go into second,
then immediately shift back to low so it will stay in second as long as
i want and shift back to drive when it's wound out in second and it will
go into third.
So a first gear start valve body isn't that important to me. especially
since Sasco wants $350 for one.
