Seriously, this threads response's are lame! I can't believe I just read most of it. OP isn't asking if you can peel out in your manual transmission.
Sounds like your tranny is slipping. Have you serviced it? Fluid condition? What RPM does the converter stall? How does it drive on the street going up hills?

Definitely check the fluid and change if you haven't already. Could get it flushed even, but be sure they just flush by letting the tranny pull in the fresh fluid itself. Toyota does this at the stealerships.

I agree start with a flush then change the filter. Plenty of shops have the equipment to do it. Including quick lube places. Ask for the "t-tech" machine that is the one that use's transmission pressure to flush the fluid. Then take it home and change the filter.

Plus, how does your O2 sensors and catalytic converter hold up to this? Oil is a converters enemy. Thats why they stop working cause the platinum gets coated with oil and the chemical reaction can no longer take place. BAD idea, in my opinion! I would say that getting the engine hot and pulling a small vacuum line and sticking it in water while revving the engine works much better. Yes, ATF has detergents. But all its going to do is gum up the intake manifold. The water in a vacuum hose is more like steam cleaning the inside of your engine. Its best to let the engine run for a bit afterwards to make sure ALL moisture is gone. And it won't render the converter useless.

atf in your intake will clean out all the gunk out of your intake.. and will generate alot of white smoke..
i recommend you starting out with you lawn mower to see how impressive the results are... (dont worry about exssive amount of smoke..) its just a good way to smoke out the neighborhood

OP like others have said check tranny fluid, does it smell burnt? check the timing of the motor. what gears do you have?

WTF? To clean the carbon out? Plus, how does your O2 sensors and catalytic converter hold up to this? Oil is a converters enemy.

Why do you think toyota has maintenance intervals for the transmission fluid? To replace the burned fluid and the filter that traps friction material.

After replacing what is supposed to be a Crane Stage II cam with a DOA cam, all I can say is Holllleeey Heck!
The truck has come alive. Peels out fine in dirt now, and goes nuts when the turbo kicks in. And I'm not done tuning it up.
It also starts easier, idles much smoother, and goes faster down the highway with much less effort.
Tranny was/is fine.
Got led to the problem by a very ugly dyno chart. The first problem was excessively low boost. After fixing that ran into behaviour that represented a significantly retarded cam (runs like a 125cc dirtbike, nothing on the bottom, way more on top). I swear they're mis-drilling the pin on 'em, the lobes seemed retarded when compared to the DOA cam. And measured 4 degrees more retarded with a degree wheel.
Shop - "We adjusted it to 7PSI" (included a turbo rebuild)
Dyno shop - "It's putting out 4.4-.75psi right now and your actuator is not in good shape"
Thanks everyone for the responses and suggestions.
BTW, here's the dyno chart from the old cam:
