The 2-speed automatic transmission in the 1966 GTO is not a Powerglide. It is a Super Turbine 300, a completely different design.
Back to our regularly scheduled topic :
I've seen very few 1966 GTOs with P/W, but I have seen a few.
I saw the most highly optioned 1966 GTO that I had ever seen a few years ago. It was at the Spring AutoFair at the Charlotte Motor Speedway. It was triple black and had almost ever option offered with ONE exception, it did NOT have A/C!
There were so many options that the window sticker had a second page. It was sold by a dealer in Virginia and the dealer that had it for sale had purchased it from the original owner. He said he found it sitting in a carport. It had been driven a little each year and had current tags on it when he bought it.
I don't remember what he was trying to get for it, but it wasn't cheap.
I wonder how many were made with the options mine had..
OK now to hear what happend to it.. well one night I was out with my girlfriend, I was 16 and had a learners permit, she was 18 and had a license..
so I thought she was leaning over to give me a kiss so I turned the wheel at the same time leaning over to her (by the way she wasn't looking for a kiss, by leaning over to turn the radio station, it was the factory am radio) well when I did this, it took not but a few seconds, untill I hit a telephone pole.. I mean dead center, you would of that I was aiming for the pole.. well friends of mine had GTO's I got the entire front end off a friend that had a 66 and 67 and had tons of spare parts.for the sum of 15.00 he was a good friend.. so one day during a severe snow storm the car was parked across the street in front of my house, I didn't take the car that night, my car was white. well a car came around the corner hit the rear quarter and caved it in along with the door and almost tore my front fender completly off.. well when they bounced off my car, that hit the fence next to my house. my mom went out to see if they were ok, they said yes and took off. well I missed this by minutes, I am looking at the tracks in the snow to see how they did it, and because there was so much snow I even had a hard time seeing from across the street that they hit my car, what gave it away was my fender sticking out about 2 feet away from where it should of been attached.. so I never drove it after that, you couldn't even open the door, it was caved in so bad,.. so after about 6 months I quess my mother got tired of me not doing nothing with the car, and said the cops said that if they car was still left on the street they woud tow it.. so I junked it for $10.00.. about a week later I went to the junk yard, it was only up the street from my house, I seen a guy leavinng with my tilt wheel, I asked him, how much did they charge you, he said $100.00.. yes I was pissed!!! it wasn't maybe 20 years later did I relize my mother made the story up to me to get rid of the eye sore.. I LOVED THAT CAR.. I had many muscle cars after that, but none, did I like as much as that one.. I have a real mad stingray now.. but I sure wish I was older and smarter when I bought that car, or at the least had a driveway to put it into.. to me at the time, was not to bad getting rid of it, the rocker panel was pushed in as much as the door, seeing that, I figured there is nothing I can do here..
