Next upgrade for the money pit. A 4-speed. Which 4 Speed is the best choice?
Here's a question that's never been made into an opinionated pole, and I feel it would be an interesting thread.
Question: There are only about two choices for moderately-priced, GM overdrive transmissions: The 200 R-4 and the 700 R-4 (including all of its nick names throughout its service). Which one of these transmissions makes a better street transmission? bowtieoverdrives.com Makes versions of both beginning around 850 dollars and ending at about 1280 dollars with respective horsepower ratings ranging from 350 to a steady diet of 600+ HP and torque. Presupposing this aftermarket companies' claims are correct about their transmissions ratings (many vouch for their reputation, so I'm inclined to believe).
I've been reading a bit about the trannys and I'd have to say that personally I like the 200 better. It still gives you a bit better than the TH350 first gear (2.74 as compared to 2.52) and has a lower overdrive than the 700 (.67). Furthermore, many have expressed dislike at the 700's steep first to second drop in ratio (about 1.5!).
What are your opinions and why?
My choice of the TH-700R4 is for the first gear being low to lower the resistance load on the engine as it now has 171,000 miles on it.
I also like the overdrive ratio being at .70 compared to the 2004R's .67 for the same reason.
Also, there is the little fact that when changing from the th-350 to either of the OD's the speedo drive and driven gears are more easily changed in the 700, the tailshaft housing on the 2004R is NON-removeable.
Both will necessitate the proper setting of the TV cable, and torque convertor lock-up in OD for longevity.
I like them both. But for your application get the 2004R it has a better gearing. 2.74:1 going to 1.57:1 is a better matched 1rst 2nd than 3.06:1 going to 1.62:1. The 2004R is also lighter and eats up a little less horsepower.
200-4R, less parasitic than the 700-4R
