How can transmmision fluid leak from rack and pinion

No, no, it just can't. Only power steering fluid goes in and out of the rack and pinion. Transmission fluid travels through the cooler lines (a supply and return line) to the radiator or a separate cooler in front of the radiator. Check again. Is it transmission fluid or power steering fluid? Transmission fluid may be leaking onto the rack and pinion.

Started my car and i believe transmission fluid pouring out

Well, there are transm. fluid cooling lines in that area, down kind of low on the car, running from the transmission to the fluid tank or reservoir on the radiator. And when the engine is running, the transmission pump is running, so the lines would be pushing fluid. One is a line bringing fluid to the radiator, and the other is a return line. If one of these lines broke, it will need replacing. You will have to find the leak and see what's up.

Trans fluid in radiator tray

You are leaking transmission fluid from either the fluid cooling lines that run from transmission to a separate reservoir in the radiator, or leaking from the reservoir itself. Hopefully, it's only the lines and may just need tightening to stop the leak.
There are two lines to the radiator's reservoir. One brings fluid from transmission to the reservoir, and a return line back into the transmission. Probably located on driver's side of the radiator, one will be near top of radiator, and one near the bottom. Small copper or steel lines that may also turn into rubber lines. Clean the area well with rags to locate the leak. Will probably need to have the car running to make it leak, while looking for it. You could also take a wrench and try tightening the fittings at the radiator, and tighten any rubber hose clamps that you see. If it's not the lines or hoses that are leaking, then the radiator may need to be pulled off for repairs or replacement. But 9 times out of ten, it is a leak from one of the lines.
When fixed, don't forget to check your transmission fluid level. Or keep adding till it is fixed.

What is a transcoolent line?

A Transmission Coolant Line is 2 Lines running from your Transmission to the Radiator 1 line is where transmission fluid goes into the radiator and the #2 line is where it returns to the Transmission, A Automatic transmissions Fluid can Run 400 Degrees or More,The Lines are to Help keep the temperture of the Fluid in your Transmission at a temperture that does'nt exceed the specifications of your transmission operating temperture. Prevent Over Heating and that would result in a Excessive Tep that would cause damage to the Internal Componets and your Front and Rear Seals. NOTE: Some Vehicles Trucks that Tow a Heavy Trailer or something else have a ADD on or some come from the factory with a Truck or SUIV that has a TOW Package on it, if this has this option the Transmission Lines will not go through the Transmission they will go to the Optional Transmission cooler ,thats normally located in front of your Radiator for much better cooling ,it actually works like a Radiator it has Fins and tubes with a Inlet tube and a Outlet tube. This is a Much more effficent cooling Component for your Transmission. Hope i have answered your question. And given you the Help you needed. Thank You.

When you change fluid and filter, if it doesn't seem to be be taking enough fluid, you need to check the return cooling line. Loosen the return line ( the back one ) and have someone start the vehicle and put it in gear. If the check valve by the radiator is not plug you will have fluid pumping out. THIS ONLY TAKES A SECOND OR TWO, so don't let it run too long. If no fluid comes out, then the check valve is pluged and you need to replace your cooling line from the radiator to the transmission. This a common problem that cause the transmission to strave for fluid and burns what is in it. Remember to always check fluid level in Neutral and use Plus4 transmission fluid. Good luck.

Brownish fluid leaking from the small mannifold on the passenger side of the car in front of the this transmission fluid?

Good chance it's the transmission fluid. The passenger side of the radiator is the transmission cooler side and the coolant is leaking from the transmission lines. There should be two lines, one on top which is the inlet and the bottom one which is the return line. Check to make sure there is no corrosion along the lines or that the line has not come loose at the radiator. Locate the leak and repair or replace the lines. Good luck and take care not to run low on transmission fluid, low fluid in the system will cause the transmission to burn out.

you can add transmission fluid through the dipstick tube for the transmission. as far as the lines, most transmission fluid lines are rubber in the middle and aluminum on the ends, so they shouldn't rust. if its leaking fluid that fast, its probably a hole in the rubber part. also make sure the dipstick tube is seated well in the transmission. neither one of which is hard to fix, just determine where the leak is coming from first
