What can you guys tell me about the AOD transmission in the 92 f150s the good bad and ugly. Im looking into transgo shift kits could I get pro's and cons aswell.

 

What are you asking? Do you have a truck with an AOD? Is it working? Have you followed the maintenance schedule? Click these & read the captions:

Sorry about the lacking info. I have recently bought a 92 flareside f150 5.0 4x4 with almost 300k on the odometer and a true mileage unknown on the title. I believe the truck does have an AOD transmission but fords are new to me. I'm not sure how well the truck was maintained before I acquired her. But the truck seems to run and drive ok minus a few issues. I need to do a trans fluid and filter change and was looking into transgo shift kits. I guess I was just looking for feed back on the situation. The truck is my daily driver for now but I want to eventually be able to turn it into more of a toy for crawling

 

If you look on the door jam there will be a VIN sticker with a transmission code - you can also crawl under the truck and take a pic of the transmission pan and post it here and we will be able to tell you what it is.

How do you know you need to do a transmission fluid change? How does the fluid look on the dipstick?

It's my humble opinion that these old ford automatic transmissions tend to tell you when they are having problems - otherwise they should just be left alone. I've seen more "I just flushed my auto transmission and now my transmission won't shift right" threads than I care to remember.

 

Do you have an OD button on the end of your gear selector ?

 

The pan has a pretty bad leak and fluid is low. Im nervous to do it because of the mileage and not knowing the condition of the transmission

 

No the OD option is on dash. I think its P R N 1 D OD

 

First off find out where the leak is coming from if its external like a pan gasket, cooler line or something like that fix it. If you don't know when the fluid and filter was changed last then do a fluid change and filter replacement (not a flush). Now running the trans low on fluid is asking for trouble, make sure its at the correct level and the fluid isn't brown or smell burnt, when dumping the oil make sure your oil isn't full of debris like shavings and metal bits, the torque converter if applicable will have a drain on it as well, you'll need to turn your engine over by hand with a breaker bar on the crank pulley or have somebody bump the starter while looking at the torque converter inspection hole at the bottom of the trans bell housing inspection plate to get all the fluid out of transmission to replace (make sure you use the correct fluid to refill as well like DEX MERC or ATF, don't get anything better or different cause it's likely not compatible with your trans.


Now, if you do see debris in the pan and oil if its minute little and i mean small little hairy like shavings then that's likely normal wear with slight discoloration then it's indicative of normal wear if the truck has higher mileage, If you see large metal bits and shavings in the pan and the oil smells burnt then your looking at an eventual rebuild of the transmission as this indicate there is wear of the internal parts in the trans that could have been caused by lack of maintenance, transmission out of adjustment, overheating the transmission, and wear and tear over the years that has caught up with itself.

If your transmission truly is an AOD, there will be a TV (Throttle Valve) cable hooked to the transmission and goes to the throttle of the engine, this allows the transmission to know when to shift. The TV cable's adjustment is crucial to the life and proper operation of the AOD. Now with that being said if you find that your transmission isn't shifting correctly or is shifting too early or delayed this is partly to do with the TV adjustment. I would highly suggest you take the truck to a reputable transmission shop and have them road test the truck to see if the transmission needs to be adjusted (reason I say this is if the TV cable isn't adjusted properly and this can be applied to a new or old transmission you can easily fry an AOD in a matter of a day. The proper way to adjust the AOD is with a pressure gauge hooked to the test port and then make an adjustment to the cable according to the recommended specs. (but I will say this a worn or damaged transmission may have different pressures or variables that a qualified transmission shop can see that a normal person cannot and can avoid a costly repair if applicable.

Another thing to consider is transmission temp with an AOD (or any other automatic) if your pulling or off roading the truck this will produce heat is to look at installing a sizeable auxiliary cooler to keep the transmission oil temps in check. A trans temp gauge is a valuable addition that can aid you in keeping your trans happy and healthy for its lifespan.

For the shift kit I'd lay off on the install of one until you can see the full scope of the health of your transmission and make sure the service and repairs get done first.

For a bottom line suggestion I'd fix the leaks and service the transmission and go from there, a cooler is a wise suggestion as well, If you do notice any wear its likely catching up with itself and will need to be dealt with at some point.

Good Luck.

 

Sounds good I'll give those avenues a shot I appreciate the fed back

 

Is there any reason to think 300Kmi is not the actual mileage? '92-up trucks are generally VERY difficult to alter, other than by swapping the instrument cluster or PSOM.If you read that first caption above & follow the links in it, you can positively ID it, and post pics of it & the rest of the truck.If you rely on it, the last thing you should be considering is any "performance" modification - especially aftermarket. MAINTENANCE and repair are all you should be thinking about right now.Why?Assuming it's in decent shape, it's not a particularly good choice for a rock crawler. Flaresides are relatively rare, which is slowly making them more-valuable.Don't assume that the leak is from the pan just because it's wet. It's at the bottom - all leaks drain there, including a PSF leak (which is probably the same ATF). Wash the engine & undercarriage thoroughly, let it dry, top up the fluids, and then watch from underneath while it idles to find the actual source of each one. Use a flashlight & inspection mirror, and your phone camera to see where your eyes can't.

Keep it topped up. I recommend using ONLY MotorCraft Mercon.Then don't. Use the best fluid, and add an external filter as the Ford TSB in this caption recommends:

This is also important for certain AOD TV cables:

1 should be at the Right end; OD should be next to N....linked in my first post.
