Fill er Up
Rob, pretty easy!
After installing the oil cooler, make sure all oil line fittings are snug and secure. Fire the engine up and run 20-30 seconds in neutral with the clutch out ( ie foot off the clutch pedal). Believe the clutch has has to be in this position for the internal transaxle oil pump to be engaged and pumping fluid within the transaxle. Kendal if you read this please verify...
Go back and remove the air filter box (two bolts, worm clamp and MAP sensor wire) and remove from car. On driver side of transaxle accessed from above remove upper transaxle fill plug. (The lower plug is the fluid drain plug which you do not want to remove....obviously) Place shop rag, paper towels etc under transaxle on upper diffuser skin to catch overflow. Cut tapered Motorcraft transaxle fluid cap and install approx 24" of clear vinal tubing (I think I used 5/16 dia). Place other end in fill hole and invert bottle to flow fluid thru hose into transaxle. Should take approx 7/8 of a quart to replace fluid now in tranaxle heat exchanger and in/out lines.
Once fluid starts to come out of fill hole, stop, clean and reinstall plug. Torque to 27 Nm (20 FtLbs). Remove rags, reinstall air box and enjoy the car. Might make additional fitting checks after operating car at temperature to make sure all are tight and secure.
Thats it! Pretty easy to do and access from above much easier than below and all the labor to take off/reinstall lower diffuser.
