98 Ford Taurus, 11万迈，想换 Transmission Fluid。Transmission 是 AX4N。
看到 Service Manual 上是这样写的 (for drain and refill):
AX4N & AX4S (Continental, Sable, Taurus & Windstar)
1. Raise and support vehicle. Place drain pan under radiator. Disconnect inlet cooler line from radiator. Connect one end of appropriate rubber hose to end of transaxle cooler line and place opposite end of hose in drain pan.
CAUTION: Shut engine off as soon as fluid flow from transaxle stops. Failure to shut engine off immediately when fluid flow stops will result in transaxle damage.
2.Start engine and idle below 1500 RPM for approximately 40-60 seconds until steady stream of fluid stops. Stop engine and add 10QT. (9.6L) ATF. Start engine and idle at less than 1500 RPM for approximately 2-3 minutes until steady stream of fluid stops. Stop engine.
3.Reattach cooler line at radiator. Add 2.0 QTs. (1.9L) ATF. Start engine and shift transaxle through all gears. Add fluid in .5-pt. (.25L) portions, until proper level is reached.
本人才疏学浅，没太看明白，是不是 transmission fluid 和 coolant 一样也经过散热器，或者另外还有一个散热器专为 transmission 服务？ 请各位指点，谢谢！
