FORD E4OD- No Flow To Cooler,After Rebuild

Posted on by Amos

CHANGE: After rebuild, your E40D transmission is returned with premature planetary failure due to a lack of lubrication, or if you checked lube flow before delivery, you find zero lube flow, and zero flow from the front “To Cooler” fitting.

REASON: The cause may be, m&match of stator shaft and pump cover creating a totally blocked “To Cooler” passage in the pump cover.

PARTS AFFECTED:

Install the proper stator shaft into the proper pump cover. The differences are as follows:

(1) 89-94 MODELS - Have a relief (Notch) cut into the pump cover on the inside diameter, where the stator shaft presses into the cover, creating a passage for converter apply oil to get into the “To Cooler” passage in the pump cover. Refer to Figure 1.

(2) 95-96 MODELS - The relief (Notch) cut in the pump cover was eliminated from the cover, and the relief (Notch) cut was added to the stator shaft (See Figure 2).

(3) If for any reason, it becomes necessary to install a different stator shaft into your pump cover, you must ensure that you are installing compatable parts.

89-94 Model pump cover with notch, MUST be used with the stator shaft without notch. Refer to Figure 1.

95-96 Model pump cover without notch, MUST be used with the stator shaft with notch. Refer to Figure 2. If you install a 89-94 stator shaft without notch, into a 95-96 pump cover without notch You will create a totally blocked “To Cooler” passage in the pump cover. Refer to Figure 3.

You also can find some car tools like elm327 and autocom cdp to help you.

Many times after a rebuild, there seem to be niggling problems which are a complete turn off for the customer. It had happened with my own Dodge neon which had undergone a transmission rebuild sometime back. As I was unable to do it myself (I had to leave town for urgent work), I had left the car with a friend to get the job done. When I returned, I found the car giving similar problems which when inspected, turned out to be faulty assembly of some components.
