Oil Feed Pipes Replacement

Oil Feed Pipes Replacement

Removal Procedure





Warning

Ensure that the vehicle is properly supported and squarely positioned. To help avoid personal injury when a vehicle is on a hoist, provide additional support for the vehicle on the opposite end from which the components are being removed.

1. Position the vehicle on a hoist and raise the vehicle.
2. Remove the transaxle oil pan. Refer to Oil Pan Replacement 4T45-E - Automatic Transmission.
3. Remove the oil level control valve. Pull the valve straight down. Do not pry on the valve.
4. Remove the oil filter and oil filter O-ring seal. The seal may stay in the case when the filter is removed.





Note: Do not score or damage the transaxle case when removing the filter neck seal.

5. Using a chisel, indent the top of filter neck seal to relax the press fit.
6. Remove the filter neck seal from the transaxle case.




7. Remove the oil feed pipe assembly bolts and remove the assembly.
8. Remove the low and reverse band oil pipe assembly seals.

Installation Procedure




1. Inspect the oil feed pipes for plugged passages, bent pipes, or cracks.
2. Inspect the oil feed pipe seal rings in order to verify the proper location of the seal rings.
Note: The oil feed pipe seals are glued into place during the initial assembly. If a seal ring is to be replaced, be sure to thoroughly clean any residual glue from the feed pipes.

3. Replace the seal rings only if they are cut, swelled, or damaged.




4. Install the oil feed pipe assembly.

Caution: Refer to Fastener Caution Fastener Caution.

5. Hand start the oil feed pipe assembly bolts and tighten to 12 Nm (9 lb ft).




6. Install the new filter neck seal into the transaxle case. A large socket can be used as an installation tool. Two mallets can be used as well.




7. Coat the filter O-ring seal with a small amount of petroleum jelly, and install the filter into the transaxle case.

Caution: Push straight down on the center of the oil level control valve in order to prevent damage to the case bore.



8. Install the oil level control valve.
9. Install the transaxle oil pan and gasket. Refer to Oil Pan Replacement 4T45-E - Automatic Transmission.
10. Lower the vehicle.
11. Add DEXRON(R) VI transaxle fluid or equivalent.

* The bottom pan removal capacity is approximately 6.5 L (6.9 qt).
* The complete overhaul capacity is approximately 9 L (9.5 qt).
* The dry capacity is approximately 12.2 L (12.9 qt).

12. Start the engine, warm up the transaxle, and check for leaks.
13. Check the fluid level. Refer to Transmission Fluid Level and Condition Check Transmission Fluid Level and Condition Check.

Note: It is recommended that transmission adaptive pressure (TAP) information be reset.

Resetting the TAP values using a scan tool will erase all learned values in all cells. As a result, The ECM, PCM or TCM will need to relearn TAP values. Transmission performance may be affected as new TAP values are learned.

14. Reset the TAP values. Refer to Transmission Adaptive Functions Transmission Adaptive Functions.
