- Now you are ready to put the valve body back into the transmission. Make sure you have all of your tools on hand and in easy to reach places. The pic below shows the inside of the transmission with the valve body removed.
Front is to the top. Note the accumulator piston retainer plate in position on the left. This is held in place using 3 oil pan bolts.
- The manual says to reattach the kick-down cable as a first step. This may be possible if you have an assistant but I found it was damn near impossible on my own. If you are doing this job on your own it's easier to reattach the cable with the valve body back in place in the transmission. It's just like doing a cable replacement.
- Position the valve body correctly, ensuring that the selector cam at the front of the transmission is correctly engaged in the gear selector valve. See pic below. While holding it with one hand, begin to install the bolts. Remember, the bolts are different depending on their position so don't muck them up.
The pawl on the valve body (red arrow) should engage in the last detent of the gear selector cam when the gear selector lever is in park. Ensure that the pin is located in the gear selector valve (blue arrow).
These are the valve body retaining bolts. It's a little hard to tell but they are different sizes. The bolts in the foreground are at the back of the valve body. They have been placed on the floor in positions relating to their positions in the valve body. You can see part of the valve body to the left facing the correct way ready to go in. The kick-down cam is visible at the top.
