HERE YOU GO.. You're SIXTEEN years old,, you check your trans fluid and you're a little bit down... You do to the parts store, or local gas station and get a QUART of TRANS FLUID.. You get and old funnel OR use a piece of notebook paper and proceed to DUMP THE WHOLE QUART into the trans dipstick tube... Needless to say,, you just dumped WAY TOO MUCH OIL into the trans and now you have to get it BACK OUT... You go to the PARTS STORE and get either a piece of 5/16 OR 3/8 FUEL LINE and you proceed to take one of the COOLER LINES off of the RADIATOR to remove the fluid... WHICH ONE DO YOU TAKE OFF?????? THE TOP ONE,, because the trans fluid comes from the trans and GOES INTO THE TOP of the cooler.... You slip the hose over the trans line,, your buddie starts the car for 15 seconds and you pump the whole quart BACK INTO THE QUART CAN !!!!!.. DOES that BRING BACK MEMORIES??????
