Checking the automatic transmission fluid is part of the regular preventative maintenance program for your Toyota 4. Runner SUV. Ideally, you should check the fluid each time you add fuel. The transmission fluid serves as both hydraulic fluid and lubrication for the automatic transmission components.
If the fluid level becomes low, the transmission will not operate smoothly, and will suffer unnecessary wear. This article applies to all 4.

Transmission cooler- manual. Ever try to move cold gear oil through a narrow passage? It takes a lot of force. Much more than auto tranny fluid which flows as easily as water, especially before it gets to operating temp. Its really not practical to try to cool gear oil with a radiator type oil cooler the way automatics are. Gear oil is very thick and sticky and dosen't flow freely like auto tranny fluid.
If you look at your manual tranny, it has fins on the outside to increase surface area and dissipate the excess heat into the air. This is all you need to keep your gear oil at proper operating temp, not too hot, not too cool. The oil has to be hot to work effectivly. Most of the heat in auto tranny fluid comes from the tourque converter which a manual does not have. Towing increases this heat dramaticly but still, it comes from the tourque converter which is really just like a fan 'blowing' fluid onto a windmill that drives the gears and driveshaft. The tremendous friction in this process is what cooks auto tranny fluid.
Unless you always drive with the clutch half engagued this friction and heat does not occur in a manual transmition. In order to fit a radiator type cooler to a manual tranny you would have to come up with some sort of pump that is strong enough to push the thick sticky oil through a bunch of skinny hoses to a cooler where it will get even thicker and stickier before it returns to the tranny. Such a pump would rob a lot of power from your driveline. Also you would have to drill and tap holes in your tranny or drain and fill plugs to fit the hoses. There are too many ways for such a system to leak or fail and it will over- cool and thicken the oil reducing efficentcy. FYI NASCAR teams use manual tranny and differential coolers and pulley driven pumps but run free flowing oil in them that is more like motor oil than normal 7.
Also they change trannys and diffs and the oils every week.
