The 4+3 is a Doug Nash trans was introduced w/the 84 model. It's basically a 4spd w/overdrives in the top 3 gears for better gas mileage. Not a true 7 spd as it implies. Actually there are no 7 speeds yet. 6 is enough. Something new I forgot is that there were no manual trans in 82. And of course there were no Vettes designated 83 but we all know that.
The Regular Production Option (RPO) Code for the true 6 speed was 'MN6' which made it's debut way back in 89. It was designed jointly by ZF (Friedrichshafen) and Chevrolet & built by ZF in Deutschland. A computer-aided gear selection feature bypassed 2nd & 3rd gears (and locked out 5th & 6th) for improved fuel econonomy (once again) (under no foot-to-the-floor conditions of course). These 'RPO' codes get thrown ard a lot in vette talk. It's the brief order # for options & standards.
So there you have it Herr Spieler. The source is "The Genuine Black Book" If I were to look for a C4 I'd pick the 35th Anniv all-white w/automatic. A beautiful car except the white bumper guard that circles the car half way up tends to yellow. If I had to have manual I'd go 89 and up.
Thanks for the info. I thought a little about a manual transmission but I quit racing of any kind many years ago and driving in the cities can be a pain when you have to shift gears constantly. My Austin-Healey had a 289 Ford with a toploader. It was fun but I'm too old for all of that now and would prefer to travel in relative comfort. I think an automatic will be my best choice but if the price is right I wouldn't turn down a 6 speed.
