flow direction of tranny coolant lines & add a tranny cooler

[stevenf12801]

'98 Grand Voyager with 3.3 Could someone please tell me what tranny coolant lines are the presure and return lines....this is for the fluid change, to pump the old out. I also want to replace the add on tranny cooler with a bigger one, any suggestions? I'm a courier and haul heavy loads at 200 miles a day. Thanks!

The line closest to the engine is the return. Throw a line on the other end and you wont make a mess.
