Re: '83 Suburban tranny

I have a few 350's & 400's around here as well as 700's in vehicles. I have an '83 Blazer with a 700 in it here so I can get some measurements off of them & try to see what you may have to do. The 400 is a 3 spd. like the 350C so the selector problem won't change. Your highway gas mileage is going to go down a little without the overdrive but, in my opinion, I'd rather have an older, more durable, transmission & suffer with slightly worse milage. If you're working it hard or towing you can't run OD anyway. I'll try to get back to you tomorrow with it.
