Im dropping the 700. I dont care about the low 1st and the overdrive. Which one would be better for me? I have a 90 Jimmy with a 350, going to 383 and I ant to keep my Np241. Im going 3.73's with 33's. Should I get the 400 or the 350? The 350 has a little better performance than the 400, but the 400 is stronger. I dont do any crawling, mostly trails and mud and to nad from work once or twice a week, on back roads, and a 2 hours highway camping trip once a year. Forget the money for the adapters and all that jazz, just looking for opinions on the transmissions themselves as far as performance and reliability. thanks Guys..... Don't you buy no ugly truck!
