I hate even to suggest this. You might be better off with a Saginaw 4 speed with the correct 1st gear and forgetting the T5. Then drive it within the comfortable rpm range you are familiar with. After all it's not a race car.
I thought of this option as well, not sure what my cruising RPM would be at highway speeds though. I'm guessing 4th gear is 1:1 just like the the 3-speed. If im going to purchase another trans though, I might as well get one that many have suggested and used in the past.
