How to Replace the Automatic Transmission Plug Adapter
The automatic transmission plug adapter may be a small part of your vehicle's transmission system, but it's also the usual source for most of the component's problems. Over time, the plug adapter starts exhibiting signs of wear, which tend to result in leaks from the transmission system. When this happens, transmission fluid will get into the conductor plate and damage it. If you are experiencing shifting problems and found fault codes that point to communication problems with the valve body or wrong gear ratios, then you need to replace plug adapter.
Difficulty level: Moderate
Tools You'll Need:
- Jack stands
- 3/8-inch ratchet
- ¼-inch ratchet
- ¼-inch ratchet extension
- 3/8- to ¼-inch converter
- E10 reverse torx socket
- E12 reverse torx socket
- 7mm socket
- 8mm socket
- Small flat blade screwdriver
- Parts cleaner, 1 can
- 1 sandwich bag
- several large broken down cardboard boxes
- 1 large plastic cup
- Latex gloves
- Compressor with air gun tip
- Safety goggles
- Handheld work light
- New automatic transmission adapter plug
Note: Before starting the installation, make sure that your vehicle has cooled down and your working area is clean and free from particles that may contaminate the transmission system. You should also wear safety goggles whenever you work on your car.
Step 1: Raise the vehicle safely and secure it on a couple of jacks.
Step 2: Take out the rear engine compartment cover.
Step 3: Clean the area around the automatic transmission plug adapter and transmission pan with compressed air or lint-free rag.
Step 4: Remove the oxygen sensor connector brackets.
Step 5: Take out the plug adapter heat shield and set it aside.
Step 6: Make sure that the surrounding area is clean. Push the plug adapter lock ring tab from 11 o' clock position to the 7 o' clock position.
Step 7: Get your large plastic cup and sandwich bag. Set the sandwich bag aside but within reach, and hold the cup under the plug connector with one hand. With your other hand, carefully pull out the plug connector and into the cup. Put the sandwich bag over the cup and out of the way.
Step 8: Using the ¼-inch ratchet, extension, and 7mm socket, take out the old automatic transmission plug adapter mounting bolt, then the adapter itself. Make sure that two O-rings come out with it.
Step 9: It is time to install the new plug adapter. Rotate the lock ring collar of the new component counterclockwise as far as it will go.
Step 10: Push the new adapter carefully into the orifice while making sure the lock ring tab is in the 7 o' clock position. Slowly wiggle the adapter back and forth while you push it in and pay attention to when it locks into place.
Step 11: Using the socket and extension, tighten the 7mm mounting bolt.
Step 12: Place the plug adapter connector back in and turn the lock ring back to its 11 o' clock position. Finally, put all the components back in reverse order a when you removed them.
