Does it sound like an airplane or a big rig when you give it gas? If I'm reading you right here, sounds like your fan clutch is stuck engaged. Need to replace the fan clutch, this is a common problem for TB's.

When I come to a stop my Sequoia stalls. When I put it in neutral or park it starts right back up, but as soon as you shift into gear it stalls. If I increase rpms then shift into gear will drive and...


Stalling is normally caused by a problem with
A) Lack of air - check your air filter
B) Lack of fuel - the fuel filter/fuel injectors get dirty
C) Lack of spark - inspect your plugs & wires
Might want to try cleaning the throttle body. Every 30k miles they should be cleaned.
Best bet however is to take it to a reliable, licensed mechanic. Vehicles 1996 & newer can have diagnostic codes read by a computer hooked up to the vehicle, identifying the problem.

Check your transmission fluid level and/or have the fluid changed. If problem persist have a transmission professional at a dealership or transmission shop service it.
