I have your same set-up w/ the auto, 5.29's, 35's, and it does fine on the freeway. the problem at high speeds isn't whether or not it's revved to the max going 65, the problem is whether or not the motor will push it up to 65-75. If I had 4.88's, the torque at freeway speed would be less, causing lower speeds. I WOULD NOT DO 4.88'S. Sure, you're at a lower RPM at 70mph, IF the motor will get you to 70mph. I can cruise usually between 60 and 75 no problem depending on incline and wind. It'll go up the point of the mountain at 60 mph. w/ 4.88's THAT WOULD NOT BE POSSIBLE, IMO. If you had the 5 speed, the 4.88's would be ok, but with the auto, 5.29's are the only way to go!
Also, w/ the auto tranny the 4.7:1 gearing in the t case is NOT possible unless you spend $$ on an adapter for a gear driven case, yank the stock chain driven case, and fiddle a bit w/ the parking pawl in the tranny.
Also, the toyota tranny is pretty much the same tranny (AW4) that comes behind the 4.0 in Jeeps. It's a great tranny!! The difference is the t case, which sucks away some of the power in the toyotas. That's why people don't like it......but you don't need to worry about the tranny itself being a piece of crap. It'll last if you maintain it and never pull a trailer w your 22re/auto combo )
please correct me if I'm wrong w/ any of this info.
