    I got the tranny out of my '93 4x4 during a few warm days Indiana has provided. I haven't dug into it yet to replace the bearings because winter is doing it's thing right now and the shop is full. So, while I wait on that, is there any advice y'all can give me so I can minimize the chance of screwing up or it blowing up when I put it back in. FYI, I do believe the rollover noise mentioned in a TSB for the '93 rangers comes from lack of oil to the input bearing due to the "Oil Trough" filling up with metal shavings. I'll have to take a pic of that when I get around to cracking the cover again. Also, would anyone happen to know if that trough oil anything else besides the input bearing? Or am I wrong by saying it provides oil to the input bearing?

    Update: I pulled the extension housing housing and it's not looking good. Looks like someone was in before me. If it's whining again this soon, what kind of damage is there? Was it a bad rebuild? Is the output shaft damaged and they didn't replace it? We'll find out in the future. I'm no tranny expert, but by the pics, whomever rebuilt it didn't do a very good job. New locknuts are like 3 bucks a piece! 20180115_113619~2.jpg 20180115_113317~2.jpg

    Wow man... I've never rebuilt an automatic, but those pics tell me you have a mess on your hands.

    It's a Manual tranny actually. You can grab the input shaft and move it in, out, up, down, left, and right. I took the shift cover off and the input bearing is trashed, the trough that I assume guides oil to it is filled with metal shavings, but the gears and syncro-hubs look good. I'm just afraid of what the end of the output shaft looks like where it meets the pocket bearing.

    Ah, my bad. Was looking more at the metal chips and stuff than the fact it has beefy GEARS! LOL The fact that the metal chips have gone all through the trans, you may be better off finding a salvage one to replace it.

    I did look into that, refurbed one on ebay is 850 big ones and free shipping. That's alot for someone making just over minimum wage. That's why I opted to rebuild, didn't look too bad when I pulled the cover, just the fact that it's been rebuilt and is already whining scares me. I'll have post a pic of the input bearing and the oil trough when I get to taking them out.

    20180117_180334~2.jpg 20180117_180246~2.jpg Yet another update, Finally got a pic of the oil trough. Also have a pic of a gear syncro-thingy. (Not actually a gear, it's 4th's syncro-thingy) But it's rounded off, not sharp like every other gear.

    $850 is a lot in anyone's wallet. I would be more comfortable buying a salvage yard MANUAL trans than an automatic. I don't know what your options are as far as salvage yards go, but I would give that some SERIOUS consideration.

    I was looking for salvage yards 'bout 2 years ago for a bed for my '88 gmc s15, nearest is "LKQ pick-your-part" and that's 40 miles away. I would actually rather put something like a borg-warner in it as my s15 definitely made that tranny look good. But I couldn't find anything that says any of Borg-Warner's Manual transmissions fit a ford 4.0l. I've downloaded a repair manual for the m5r1 and looked at some diagrams, I think it shouldn't be too bad. If I screw it up it was bound to be junk anyway. If I do have to get a new tranny, would the m5r1hd be any better than a plain 'ol m5r1?

    I don't know much about the different transmissions, but the 'HD" on the end indicates it would be a better choice if you do have to get another one.

    Ok, the thing is a bare case now, and I bet it's junk. But.... it'd still be worth getting a new tranny vs buying a new truck for 850 as I bought it for only 150. Anyway, here's some more pics. As many of you could see, whomever rebuilt this didn't use new gaskets, just way too much black rtv. It ended up clogging up the port that oils the input bearing. As seen in the upper left of the front bearing retainer pic. 20180118_141118~2.jpg 20180118_141231~2.jpg 20180118_141426~3.jpg 20180118_131959~2.jpg

    Also forgot to add, pocket bearing is wore badly, but main output shaft is fine. Input is junk, all burned up and syncro-thingy for 4th (i'll find the real name adventually) is rounded off.

    Wow! That is just about as trashed as it can get!
