Hi all.. I tried searching, but dont really know what to call it to get the search results I need..
I have an 86 302 EFI 4x4 with an AOD trans, and its leaking where the shifter linkage goes into the transmission housing just above the pan. Could anyone that has done this seal before give me some tips or "remember to" advice? I found one video of a guy doing it, and it seemed to use alot of movie magic and skip to the "Its that easy" part alot. I'm not lacking mechanical ability.. just lacking experience with transmissions. Any help or feedback would be greatly appreciated. :beer

thats an awesome picture... it would be the manual lever.. the little $1.70 seal. I called a few transmission shops today to get price quotes to have it done.. $160 installed and TV cable adjustment. All three shops I called said it depends on the AOD, some it can be done without removing the valve body, some the Valve body has to come out. Not sure what the diff is.. AODE maybe?

hmm.. I dont know enough about the AOD's to argue with them about it. It threw me off when the first one said that.. but after the other two said the same thing.. I figured there may be a bit of truth to it.

yo B,
I sent a PM to the authpr; just in-case ATSG has a mini CD on the AOD for $30.00; "
This is the DOWNLOAD link for AOD_DL AOD Transmission found in many Ford domestic vehicles 1980 to 1991. Covers transmission assembly, dis-assembly, diagnosis, and troubleshooting." https://www.atsg.us/atsg/manual-download-1/aod-dl.html

The shift lever I was able to take out of an AOD and 4R70W pretty easily with the pan dropped if I remember correctly but it's been a few months. I think it used a nut on the inside of the case that had to be taken off to get linkage arms off that went to the parking brake an valvebody. Then u remove a small pin that holds the shaft in the case. The shifter shaft should come right out

I took them out so I can cut a and weld the shifter arms when I swapped a 98 explorer 4R70W into my 90 f250 that had a AOD. The AOD used linkage where the 4R70W used a cable

well... I reckon I'll probably shell out the $160 bucks, bein that they said they would adjust the TV cable also.. This is the most reputable shop in my area for transmissions. I hate to spend the money, but after I buy the filter and fluids... aint really saving that much having them do it.. lol.. I think it really boils down to my "I dont wanna" meter being pegged out..

Miesk, I'll look into that DVD, cause at some point, I'm sure i'll need to dig into this tranny and when It comes to a real costly repair... I would rather do that on my own.. Or at least try it on a JY tranny first. Thanks for the info Kind Sir.

yo,
OK, I capice!

How about asking the shop to give you a copy of the TV adjustment procedure? It is Most Difficult to obtain the PSI data using the pressure gauge method.


Here is they typical info on the www;
"NOTHING can ruin an AOD transmission as quickly as improper TV settings. If you are unclear or uncomfortable with the procedure, do not attempt this adjustment yourself. This information is meant to supplement, not replace, information that can be found in Ford service manuals for adjusting the TV pressure. Always follow general shop safety rules (never go under a car supported by a jack alone, always chock the wheels, etc.) when perfoming automotive work.

Without a Gauge

If you don't have a gauge or you are looking for a roughly-correct place to start, you can remove the cable from the throttle body lever and adjust it so that the cable is neither slack nor under tension when the cable is reinstalled on the throttle body lever. This will get you fairly close. We do not reccomend this for a final setting. You should always use a gauge to verify your TV setting.

With a Gauge

You will need to install your gauge into the TV test port on the transmission. The port is an eight inch pipe thread and is located on the passenger side of the transmission. Toward the back of the transmission, above the pan rail, you will find two 7/16" headed pipe plugs side by side. One plug is level with the outer edge of the pan rail while the other plug is recessed. The recessed plug is the TV test port. Since this port is recessed, you may not see it if you are looking straight up from under the transmission. You will have to try to see over the pan rail.

Remove the TV test plug and install the fitting for your gauge. Attach the line from your gauge to the fitting in the test port. With the engine running, the gauge should read 0 to 5 pounds at idle. If you happen to have the special tool for testing TV pressure (installs on the ball end of the cable to pull it a measured amount), the reading on the gauge should be approximately 30 psi with the tool installed. If you don't have the special tool you can tape the gauge to the outside of your windshield with the numbers facing in and have an assistant ride with you to watch the gauge. Normal acceleration from a stop should produce around 30 psi. You also want to make sure that as soon as you start to apply throttle, the gauge reading begins to rise. This is a good indication that there is no slack in the cable. If you would like you can also check the WOT pressure with the gauge mounted this way. It should read around 85 psi."

Thanks Miesk, I will see If I can locate that Special TV adjustment tool.. I am a little OCD and the "close enough" adjustment doesn't set will with me. So I'll leave it to the pros until I can locate the tools to do it my self.

Thx for the info! I did a copy/past to a word doc to save on my laptop for later use.

Ask the shop if the Baumann pressure settings are what they use; ask for a copy from any manual or other source they use.

I just happened to see an AODE at the junkyard today with the pan off already. decided to take a pic just incase you do decide to try it. its going to be very similar between the AOD/AODE/4R70W. the shafts between them is very similar but the AODE/4R70W will use a shaft that can have the MPLS sensor on it.

as I thought, you pull out the little pin that holds the shaft in. you can use a pair of pliers and twist it while you pull out. with that out you can slide the shaft around a certain amount allowing you to get a wrench on the nut on the inside. with that nut off you can then remove the linkage arm that goes to the valvebody and parking brake linkage. no need to pull the valvebody. I did it pretty easily when I had the tranny in the truck.

It's NOT the same as his.
I know he has a AOD. I know the AODE/4R70W don't have a TV cable. I was talking about how to replace the seal for the manual shift lever, not for the TV shaft. the process to take the manual shift shaft out is the same between the 3. the shafts are very similar. I could fit an 4R70W shaft in an AOD and vise versa but that would be pointless because the AOD shaft cant use the MLPS

well.. dropped it off yesterday.. Shop called me today and said that the shaft has a groove worn in it and the new seal is still leaking, they are trying to locate a new shift lever shaft (whatever its called). So we shall see.. I havent had a chance to talk to the Tech yet to see what manual they are using.
