33's wouldn't be stock, though. No Toyota truck or SUV came with them. 31's would be that. Even so, two inches makes a big difference. Or, more correctly....one inch.

I'm running the 5.29's with 35's as well on an auto. It does the job that I need it to. I do see what others means about hills but its not that bad. I had 4.88(stock) when I ran my 33's. 5.71's don't hurt but 5.29's will get the job done.

[soliloquy]Keep in mind all opinions below are at altitude, which exaggerates any gearing/power issues.[/soliloquy]
You've obviously not driven a properly geared one to appreciate the difference.
Molly's truck is an auto with a minty fresh V6 motor and 5.71's and it SUCKS compared to my truck (33's, manual, 4.88's). It won't hold the overdrive on anything remotely uphill or into the wind at less than 85 MPH (and it's too damn scary to drive her truck that fast)

Depends on how you use the truck. The issue is not first, but the top gear (5th or overdrive). There is not really an issue of longevity/strength between the two, but an additional cooler is recommended for the auto.
If you are on the highway alot and want to be able to use the OD, IMHO you should gear the axles two steps lower than a manual tranny (stock is one step, and I think the autos are undergeared from the factory). Since 5.71's are the lowest you can go in a Toyota axle, that kinda limits you to 33's. If you want to go bigger than that, I would HIGHLY recommend a manual tranny swap.
If this is a trail only truck, or only sees city driving and will never use the overdrive, you can gear it the same or even one step HIGHER than a manual since the torque converter helps by increasing the torque at low speeds.
I should state that Molly's truck with 35's auto and 5.71's had SIGNIFICANT tranny temp issues on the highway because of not being able to hold the OD lockup until she installed a tranny cooler. If you have an auto and even think you MIGHT be undergeared, start shopping for a tranny cooler!

Ah, I see. Well, (sorry to hijack the thread) I'm 80% city, 10% trail and 10% highway most of the year, but I do like my road trips. With my 3.0, auto and 32x11.50s I cannot hold OD up any inclines with stock gearing, and I want to go to at least 33s and more probably 35s within the next year. Seems worth the cost of another tranny cooler and 5.71s to extend drivetrain life.
Thanks TC.

It probably NEVER goes into overdrive so you don't notice it as much. What RPM are you at for 70 MPH?
(For comparison, my truck is at 3000, Molly's is at 2250 if you can ever get it in OD and the torque converter locked up long enough to read it)

Contrary to Toy's believe I think I hang ok... 
At least do 5.29's 5/71's are better..
Here is the reasoning,, http://www.gearinstalls.com/410suck.htm
What you talking about Willi's?
Tranny cooler is ESSENTIAL for 5.79's... Ask me how I know.. 
I gotta go beat Troy now... LOL! Hope that helps!
