HI guy's, I pulled this out of my 1994 c1500 pickup and its in great shape its pretty basic hookup two wires to the transmission and two for a hot and negative, it would work on any type as long as its a 4l60e tranny. Anyhow it works great practically brand new believe it or not. It has 4 stages from mild to aggresive shifting. It fit like a glove in my truck in the ashtray area, just pop out your ashtray and this slides right in and was hidden away. Think I paid around for like $130.00-145.00 for it . I'll sell it at $100 shipped! thanks ....Kurt
