Hello. First of all, just want to say glad to be here! I'm currently 15 and LOVE hot rods and muscle cars of all types. I also love engines and powertrains. Let me cut to the chase...

My brother has a 1958 Chevy Apache Fleetside pickup as a restoration project. He put a Chevy Small Block 400 in it, coupled to a TH-350 tranny with a full manual valve body, shift pattern P-R-N-3-2-1. The tranny has some kind of shift kit in it, but we do not know a make or model. The engine runs like hell, but the tranny will not shift into first. It shifts into all the other gears just fine, but won't shift into first. I read somewhere ( I believe one TCIs website) that you remove the governer assembly when you install the product to help with performance. We don't know what the problem is. Any help is greatly appreciated! Thanks! Kolby
