My rpm was running high so I pulled over to check under the hood. When I popped

First of all, you should have came on here asking for help before you did anything else. Hopefully, you have not damaged your Transmission. So-o-o, first let me explain something to you--The Transmission Fluid IS NOT A LUBRICANT, IT IS A COOLANT! THE TRANSMISSION LINES ARE RUN THROUGH A SECTION IN THE BOTTOM OF THE RADIATOR TO "COOL" THE FLUID. WHEN THE FLUID BEGAN TO LEAK OUT, IT CAUSED THE FLUID GOING BACK THROUGH THE RADIATOR TO BE EXTREMELY HOT, CAUSING THE RADIATOR TO BOIL OVER. Now, you have to find where the leak is coming from. Jack up your car--one wheel at a time-and put jack stands under each wheel so the car will not fall.(you may want to buy yourself an in-expensive floor jack that comes from Harbor Freight Tools with jack stands and a creeper for about $70.00)VERY IMPORTANT: MAKE SURE YOU HAVE A GOOD FRIEND TO HANG OUT WITH YOU IN CASE YOU SHOULD NEED HELP! START THE CAR AND LET IT RUN FOR A FEW MINUTES TO MAKE SURE THE JACK STANDS DON'T SLIP. THEN, ROLL UNDER THE CAR(DON'T FORGET YOUR SAFETY GLASSES AND GLOVES AND YOU MAY NEED A DROP LIGHT TO SEE WHERE THE LEAK IS. PROBABLY THE GROMMET WHERE THE FILL PIPE GOES IN! REPAIR THE LEAK AND THEN ADD FLUID ONE QUART AT A TIME--CAUTION--OVERFILLING IS JUST AS BAD AS BEING UNDERFILLED. DON'T PUT MORE THAN MAYBE A 1/2 QUART TILL YO KNOW THE LEAK IS FIXED! OH, YEAH, GET YOURSELF A BAG OF RAGS FROM HARBOR FREIGHT ALSO. GOOD LUCK!
