Inliners International Forums General Discussion Drive Train Powerglide kickdown, ok to leave off?

I had a 66 chevy PU once with a PG in it. I put a 396 in it (back when I was young and stupid), -- no room for kick down linkage. It shifted into high at 10 MPH -- no matter what unless I manually shifted it into low. I drove it like this for several years so it would probably be OK.
