Hey guys, I'm new here. I've been searching the internet for a while trying to find a solution to my e150, and have largely been unsuccessful. Here's the problem: I've got a 1992 ford e150 with the 5.0 Liter engine, and after coming to a complete stop and then attempting to move forward again, the rpm's rev up as I push on the gas, and then a second later, the transmission slides into gear with a jolt and I can move forward. I've tried adjusting the TV cable back and forth, and only been successful in making the transmission slip worse. I replaced the transmission filter, and that made it shift smoother between gears, but didn't do anything to solve the slipping. It does not slip while I'm driving, but sometimes when I take my foot off the gas to coast and then push the gas to accelerate again it revs and then jolts into gear just like when starting from a complete stop.

I read somewhere that I should look into the ABS/speed sensor on the top of the rear differential cover, and the MLPS sensor. (do I even have a MLPS sensor if I have a TV cable?) What should I try? should I make the TV cable tighter? Also, I pulled the codes using a paperclip, and only got one: 225. Somebody help! what does it all mean?

 

Another thing: My cruise control does not work. I cracked open the clockspring and re-soldered the ribbon cable to get the horn back. I assumed that the cruise wire broke loose again while I was putting it back on, but maybe it isn't broken? Could this all be linked together somehow? just trying to provide as much background as possible.

 

If you have a tv cable then the trans is not an electronic trans. It does not have an MLPS. Cruise does not affect it.

You can get these symptoms with low trans fluid. Have you checked it? It needs to be checked warmed up and idling in park.

Running it with low tv pressure can destroy the clutches in one or two shifts. If you made it slip worse I fear that trans is toast.

 

That is so not what I was hoping to hear. If anything, the transmission fluid is too full. When I changed the filter, I warmed it up and added more fluid and might have put a little more in than it needs. After adjusting the TV cable too loose, I drove it about 200 feet, then re-tightened the cable. So what you're saying is that the reason the transmission is slipping like it is, is probably because it's worn out?

 

Most likely, yes. It may be worth your while to get a transmission pro to drive it and give their opinion. This is hard to diagnose without seeing the van. Hint: Aamco doesn't have anyone that meets this criteria.

 

hmmmm. Will an AOD from a 5.0 mustang fit in an e150 with a 5.0? Can a mechanically inclined do-it-yourselfer replace this transmission at home?

 

I had a '92 F-150 that was acting the same. Changed the filter/fluid, no help. I bought an AOD from a place in Florida (I'm in Texas), monster something? I think I paid ~900 for it but that was 9 years ago. I swapped out the old one in the garage, put it up on jackstands. My grown sons helped, they do their own car work as well so with a helper it is possible to do on your own.

The only issue I had was the shifter was wrong so I had to drop the pan and swap the new one for the old one.

The older son has the truck now, still going strong.

Thanks so much for all the advice guys! I'm gonna pull a transmission from a 5.0 fox body mustang and get it done over some weekends. Any particular advice before undertaking such a project?

 

My advice is to do some research on the different lengths of AODs that were built. There were many different length tailshafts and extension housings produced. I don't know enough about the AOD to be able to tell you which models have the same length as your current transmission. I do know it opens a whole can of worms if you get a trans with a different length.

 

If they're set up like the older C4's and C6's, the shifter lever on the transmission will be "up" instead of "down". As for different tail lengths, all that requires is a shorter or longer driveshaft.

 

And sometimes moving the transmission crossmember. And sometimes the wrong tooth count on the drive gear for the speedometer.

 

Listen to Mark's advice. I ordered the AOD for a 1992 F-150 XLT Supercab and still got the wrong shift linkage. If you can pull the bad trans first and compare everything to the Mustang trans, you will save some surprises later.

Think seriously about getting a new converter while it's all down. You don't want to have to do it all twice.

 

Wouldn't the shift linkage and speedo gear be something I could swap over from the original? The reason I'm looking at a foxbody aod is because there is an abundance of them on Craigslist. I'm finding it pretty tough to find anything other than a foxbody aod actually. I'll probably go ahead and get a new torque converter, thanks for the advice. As for a longer driveshaft, is there any answer there other than a custom fab one? Anything from a junkyard that would happen to fit?

 

Speedo gears will usually swap. I did the linkage swap on mine

but you don't just change the arm. I had to remove the pan, unfasten a couple of things, GENTLY slide the shaft out then thread the needle to put it into the new trans.

Another point to watch for, something from a Mustang MAY have a shift kit in it causing a more abrupt gear change than you want. Mine shifted "harder" and thinking the TV was misadjusted, I tried a couple different settings before setting back to factory. It wasn't an awful ride, just more abrupt in upshifting and a noticeable change from the original.

I disassembled the old trans (gotta know, ya noe?) and found something that looked like a thrust bearing in the process of being ground to dust.

 

You've got a 92, you may not have a speedo drive in that transmission. That would be the AODE transmission. The speedo gets it's input off of a ring gear inside the rearend. Measure your transmission from front to rear before going shopping for transmissions, that will save the guess work in that regard. I've never paid much attention to AOD's but most all I have seen looked to be the same length. Other Ford transmissions came in at least two tail lengths, so AOD's may have as well.
