I have to take =some= issue with this statement. Since the 200-4R is the same overall length as the TH350/Powerglide and can often be mounted as easily as by flipping the trans mount around, I found it a very easy install.

Once you need to start shortening driveshafts and getting them balanced and phased and all of that it gets harder, but you have none of that with the 200-4R.

You're spot on that the TV cable must be adjusted properly, but I'm not a rocket scientist and I've never had a problem doing so. You have to respect it and take it seriously, as it is NOT just a kickdown.

The 200-4R is somewhat weak sauce in stock form, but if I understand correctly, is stronger than the 700 once built similarly. I ran one in a 4200lb car with 600lbft big block and a converter and drag radials and it hooked and ran 12s for years!
