Guys, trying to track down some transmission information, and I’m not even sure where to look. Maybe you can help.

My latest project is a ’68 350 convertible. It has it’s born with engine, but a PO swapped out the transmission years ago with a 70’s something TH350.

The (what I believe is original) electric kick down switch and bracket came in a box of parts with the car, as well as the original wire harness with the two wires for the switch.

The 70’s something transmission has cables for a kickdown, and they are just laying on top of the engine.

So here is my question:

How can I tell if my car came originally with a TH350 or a powerglide?

The PHS just says “automatic”, and nothing more.

People keep telling me that the ‘68-’69 TH350 did not come with an electric kickdown.

The shifter has an L, 2, D as if it were a 3 speed. (verses L and D for a powerglide). Looks original too.

So I’d like to put in whatever would be ‘correct’ for my car, but all I seem to find is a TH350 with cable kickdowns.

Any idea where to start? PHS has been worthless in this aspect.

My car is a July 1968 build, so VERY late in the model year if that matters.
