NISSAN RE4RO1A/3A PLANETARY FAILURE DUE TO LACK OF LUBE
COMPLAINT: Before or after overhaul, vehicle equipped with an RE4RO1A exhibits planetary gear train failure, due to lack of lubrication.
CAUSE: The cause may be one of the following. 1. Inadequate cooler flow. 2. Excessive output shaft to case bushing clearance. 3. Excessive clearance between the output shaft bushing and turbine shaft. 4. Forward clutch rings leaking on the low sprag inner race. 5. Internal leak on the turbine shaft. 6. Cooler relief check-ball capsule and spring leaking at the back of the case. 7. Bushing not removed from the front sun gear.
CORRECTION: 1.Insure that the vehicle has sufficient cooler flow. Minimum cooler flow must be no less than 1 quart per 20 seconds when the vehicle is "HOT".Warm vehicle until operating temperature is over 160 degrees. Raise and securely support vehicle on a lift (For safety concerns, do not attempt this test on the ground). Once operating temperature has been reached, shut motor off.Disconnect the "Rear" cooler line from the transmission and place the end of the line into a bucket or suitable apparatus to keep oil from spilling or splashing. Have a helper get into the vehicle and start the engine. Apply the parking brake then hold the brake pedal and move the selector lever into the D position. While holding the brake pedal on, allow the vehicle to idle in drive. IMPORTANT: Visually check the rear cooler line fitting at the transmission. THERE MUST BE NO OIL COMING FROM THE CASE. If there is oil coming from the case, the most likely cause is a leak at the forward clutch rings on the low sprag inner race. Count for approximately 20 seconds then move the selector lever back to park and shut the motor off. Measure the amount of oil in the container. There must be a minimum of 1 quart of oil in the container. If less oil flowed from the radiator, disconnect the front cooler line and repeat the test. If the test still shows insufficient cooler flow, the problem is most likely a restriction in the valve body. If cooler flow is now sufficient the problem is a plugged radiator. Repair or replace the radiator as necessary (Refer to Figure 1 for information on replacement cooler element).
2.Inspect the case bushings in the back of the case for wear (Refer to Figure 2). If needed insert the output shaft into the case and check for excessive play from side to side. If side to side movement is excessive replace the case bushings. Using compressed air and a blow gun, direct air pressure into the different lube holes in the output shaft and make sure there is no debris blocking the holes and that air passes through the holes freely.
3.Inspect the output shaft bushing where turbine shaft rides (Refer to Figure 3). Insert the turbine shaft into the output shaft and move the turbine shaft from side to side. If excess movement is detected, replace the output shaft bushing.
4.Inspect the forward clutch sealing rings that are installed on the low sprag inner race (Refer to Figure 4). Make sure there are no cuts or nicks in the rings. Carefully remove the ring from the inner race and bore fit the rings in the drum. IMPORTANT: There must be no more than .003’‘ end gap between the butt ends of the rings. Replace the rings, or the low sprag inner race if necessary.
5.Inspect the turbine shaft for cracks and blow a small amount of compressed air approx. 30 psi. Into either end of the turbine shaft (Refer to Figure 5). IMPORTANT: No air must pass completely through the shaft from one end to the other. The shaft is blocked in the middle to separate converter release oil and lube oil. If this shaft leaks, all lube will be drained when lock-up is engaged.
6.Remove the cooler relief check-ball capsule and spring from the back of the transmission case (Refer to Figure 6). Install a solid cup plug or tap the case and thread in a pipe plug. Note, late model cases (after 1994) had the check-ball capsule and spring eliminated from the factory.
7.Remove bushing from the front sun gear and leave it out (Refer to Figure 7). This will allow more lube to pass through the sun gear to the front planetary. Note, if a new front sun gear shell is purchased from the factory, no bushing will be installed in the sun gear. Do not install a bushing into a new sun gear shell.
Most Nissan vehicles have what is known as a fin type cooler. This type cooler becomes easily restricted causing poor cooler flow resulting in lack of lubrication to the planetary gear train. Cooler line flushing machines cannot sufficiently flush this type of cooler. The spiral cooler shown in Figure 1 below is a replacement cooler. This cooler may be installed instead of replacing the entire radiator. This cooler is available from Nissan the part number is 21606-15V25.

FORD AXOD PREMATURE PLANETARY FAILURE
SEVERAL MODIFICATIONS CAN BE MADE IN AN EFFORT TO HELP IMPROVE LUBE OIL FLOW TO THE PLANETARY SYSTEM AND THEY ARE AS FOLLOWS: 1.Drill the torque converter fill hole in the valve body spacer plate out to .062" (l/16 Inch). This is the hole marked I'D" as shown in Figure 1. Drill the rear lube orifice in the valve body spacer plate out to .078" (5/64 Inch). This is the hole marked "1" as shown in Figure 1. 2.Trim the rear lube check valve spring, which is located in the valve body, until the check valve sits approximately l/16" above the machined surface of the valve body (See Figure 2). This will require approximately 3 coils be removed from the spring, and always install the cut end of the spring back into the valve body first. 3.Inspect the bushings in the rear planetary support, as these bushings can move out of position and block the lube hole located in the support between them. The 1988 and later rear planetary support has a new second design, wider, one piece bushing with a groove and lube hole in the center. This will provide more surface area to prevent the bushing from moving. Refer to Figure 3. You can get more car tools MB Key Prog and Nissan Consult 4 for help from http://www.autobossv30.org/ . The later rear planetary support, with the 2nd design bushing, will retro fit back to ALL previous models and is highly recommended. The new design rear planetary support is available under OEM part number E6DZ-7A130-A. 4. Replace the rear lube tube seal with the early design THM 200 (2 Piece) low/reverse support seal. Refer to Figure 4 for installation. The THM 200 two piece seal will now provide additional flexibility and still retain its ability to seal against the rear planetary support. The support CAN rotate in the case lugs, and when the support rotates it WILL damage the one piece seal. NOTE: WHENEVER THE REAR SUPPORT HAS BEEN REMOVED FOR ANY REASON, THE REAR LUBE TUBE SEAL MUST BE REPLACED. 5.Install "Double Bushings" at the rear of sun gear as shown in Figure 5. After both bushings are in place, ensure that lube oil hole in the sun gear is not blocked.

NISSAN FRONT OR REAR DRIVE PREMATURE PLANETARY FAILURE
COMPLAINT: Planetary gears failed due to lack of lubrication, while the hydraulic system and friction material does not seem to be damaged.
CAUSE: Lubrication may be restricted or even totally cut off due to clutch material from the converter clutch clogging the fins or tubes inside of the radiator cooler.
CORRECTION: 1. FRONT AND REAR DRIVE. After a transmission repair, perform a cooler flow test on all suspect vehicles. There must be at least l(one) quart of oil every 20 seconds returning to the transmission at idle. If the vehicle uses a tube type cooler, then it may be flushed using conventional methods. If the vehicle uses a fin type cooler, then the radiator MUST be replaced. See figure 1 to determine the cooler type in the vehicle that you are working on.
Figure 1:http://flic.kr/p/dYVPby
2. RE4RO1A and RE4RO3A Check the case bushings for wear and replace them if they are worn. Also make sure that the case bushings have not moved so that they block the lubrication feed passage to the output shaft. To assure maximum lube to the output shaft and planets,remove and discard the orificed cup plug, the lube relief ball, and the spring as shown in figure 2 and INSTALL A SOLID PLUG IN PLACE OF THE ORIFICED CUP PLUG.

Entering Information of X-431 scanner's Troubleshooting
Mood:
blue
1.Why can’t I input data using the Soft Keyboard (on-screen keyboard)? Either the position where the cursor lies cannot be edited, or you haven’t activated the cursor on the input position. Use the stylus to select the field you wish to edit. When the cursor blinks, you can input the data.
2.Why is the screen inactive after the cross-cursor appears on the screen? How do I adjust the screen? The system is calibrating the touch screen. The machine will work after this calibration is completed. Refer to the section “Calibrate Touch Screen” in your car diagnostic tool User’s Manual.
3.Why can’t I click any of the buttons on the screen? I’m pressing the ‘Start’ button, but nothing is happening. You need to adjust the touch screen. When the machine powers up, press the ‘Hot Key’ located just above the”Power button”/You will see a cross-cursor appear on the screen. (You may need to press the ‘Hot button’ twice on some machines) Click the center of the cross-cursor with your stylus or pointing device. The cross-cursor will then move to each of the four corners of the screen, continue clicking the center of each as they appear. This completes the adjustment or calibration of t he screen. You should now be able to click the available buttons.
CF Card 4.How does the CF Card fit into my machine? There is only one way for the card to fit. If you feel yourself forcing it, turn it over and try putting it in on the other side. The end with the holes always faces down.
5.Why doesn’t my unit recognize my updated CF Card? There are two possible causes for this: (1)Some programs are lost or damaged. Download the latest “System Data” from the download page at www.x431.com, and update again. (2)CF Card is damaged. Contact your local dealer for replacement.
6.Why doesn’t my unit recognize my new (replacement) CF card? There are two possible causes for this: (1)The original CF card has not been fully copied. Format the card and perform the update again. (2)The CF card reader is not compatible with the CF card. Contact your local dealer for assistance.
7.Why is the unit telling me that no CF card is found when the machine is turned on? Check to make sure that your CF card is firmly inserted into the machine. If it is, it may be damaged. Try formatting it and reinserting. If this doesn’t correct the problem, you may need a new CF card. Contact your local dealer for replacement.
8.I’ve connected my CF Card and reader to the computer, but it’s not showing up in “My Computer.” How can I correct this? One possible cause is that there may not be a driver for the CF card reader in the com-puter. The default driver is included with most Windows operating systems as well as Mac OS 9.x/OS X and Linux 2.4.x However, there is no such default driver included with Win-dows 98. If you are using a Windows 98 system, you must install the driver from the included CD-Rom or from http://x431usa.com/downloads.htm. When it is installed correctly, a“remov-able disk” icon will appear in “My Computer.” Usually, it is listed after the built-in drives, such as the C:\ drive. The removable drive will be the new letter. For example, if you had a C, D, & E drive before installing the CF card reader, afterwards you will have an F drive. This would be the removable disk.
