Exclamation Transmission woes w/ 1981 2WD 22R

I come here because I have absolutely no faith in a response from the loser ricer posers that no doubt lurk ToyotaNation and ToyotaTruckClub. I've gone there with problems before and NEVER got a response of any kind. Only places that have been at all helpful aren't even dedicated to that vehicle manufacturer: JustIH (since I also own a 62 Scout) and DodgeIntrepid.net (need I say why?).

The below is a direct copy paste of the post I made on the 2 aforementioned Toyota sites (that have never been of useful help).

The engine is definitely on the worn side but still runs fine. Now the transmission (a 4-speed) after nearly 2 years of ownership is starting to have some issues. 3rd-gear has always been noisy @ about 20-25mph...isn't as bad when I put pressure on the stick though. This can be annoying but not intolerable. But over the last week the transmission has popped out of gear a few times after engaging the clutch when slowing down from 4th gear. This is followed by the somewhat subdued grinding of gears that does not go away unless I come to a complete stop...and won't happen again until it decides to pop out again. I do have a book on the truck so the different possible causes are known to me...but I'm thinking a replacement is in order since the truck had anywhere from 150k-230k when I got it...and I've put about 20k on it since I got it. Below are my questions since now I'll be looking for a possible replacement while I still have time.

First: What model year range of trucks have compatible mounting to the 81' 22R? This will aid in finding a donor locally.

Second: Would a 4-speed (or 5-speed if there are any) from a 20R equipped truck bolt right into place and is there there anything I should know that may be different from the later models?

IF I could find one would I be better off going with a 5-speed and would this require me to also swap the axle to preserve the proper ratios? Additionally would the 5-speed of an otherwise compatible year bolt right up to the engine w/o issue? As this truck is a commuter, I'm not interested in 4x4. (I have a 62' IH Scout I'm working on for that purpose. )

NOTE: I did read elsewhere on this site that going from a 4-speed to a 5-speed may or may not require the moving of the support bracket.

Also, the only transmission swap I've yet done...actually the entire drive train...was with a Corolla. Did a full drive train swap out of a 3-speed auto from a 78 and installed a 5-speed from a 77. The 3-speed had the problem of occasionally slipping and wouldn't "park" in Park. Had to use chalks on ANY and all inclines to prevent rolling. So I'm open to helpful hints.

I've never yet had extremely major issue with this truck, and at the moment is my main commuter with its 28-30mpgs. The only 2 serious repairs was a waterpump (the one that came with the truck) that seized on me on the way to work, and a blown rear main oil seal (took 5qts of oil and stopping and adding a quart about every 15miles for 75miles to get home). I have an alternate driver that is OK on the gas but I like the truck better even though it is and DOES look like a beater (within and without). Faded primer-red with a shot interior.
---------------------------------

Began today with a check of the tranny fluid. Still had enough for it to begin pouring out when I took out the fill plug (the truck perpetually leans a little to the left & where its parked isn't exactly level to begin with (no garage). Checked the oil but nothing strange was found. Pulled the drain plug and got a good few finger fulls as it drained - after the oil itself wicked away there was the expected paste of metal filings given the transmission's age...but there was enough to make fairly significant paste. Aside from the innards being worn to an inch of their life...any other hints at what would be causing the reported grinding? The book on the truck gives a short list but doesn't really elaborate.

At this point I'm fairly convinced the transmission is literally on its last legs...but an oil change of new 80W90 might be enough to postpone the inevitable. But this is still a universal issue.

What makes this all a royal pain in the arse is that this past Friday (no problems to otherwise report at this time)...I put 230$ worth of new tires on (2 new fronts and 1 road hazard replaced rear). So can't afford NOT fixing this thing.

Smile Good news...Search Over...<crosses fingers>

Looked into possible sources for a replacement transmission: Exact versions are not known but I'm exploring all avenues. These are what was found just today within the past 3-4 hours.

One possible source is from an 87' with a 5-speed but it's a 4WD. The year disparity might or might not be an issue since he donor also has the 22R...but the driveline would definitely need to come with it. This one is relatively close by (distance wise) but @ an unknown price yet.

Possibility two, all I have is a phone number from the same shop that pointed out source one.

Possibility three, is from an 88' and is also a 4-speed. This one is the best initial possibility despite the year difference. The owner runs an appliance shop that I pass by every workday so getting it wouldn't be a problem. Wants 80$...sounds fair to me.

Possibility four, ended in a thorough bust. A local had a 74' which is basically ended that search.

Possibility five....VOILA found a 5-speed. Only about 10 miles away in town, It's been sitting out uncovered for at least several months but outwardly is clean, save for the input shaft which needs to be cleaned of the patina. Came from an 84' and since it definitely came from behind a 22R it makes it even better. This would have been going apparently into an early 80s Toyota RV but that project for the guy never came about so is why I have the chance here. The throwout bearing is shot but the hope is there that the existing 4-speed one will work...if not...okay. Clutch fork comes in from the driver's side instead of passenger but the 2 bell housings should swap fine...if not it's just a matter of moving the hydraulic lines. Only bad point is that no driveline to go with it...so if mine won't fit...its going to get a bit shorter. 50$...I'm jumping at it...and is reasonable enough to warrant any other issues. Will be picking it up tomorrow...

Here's to hoping all works out.

I'll see what I can about delivering pictures.

UH-OH! Complications

Here I am...all jazzed I found just the transmission I've been looking for (5-speed from an early 80s)...where all I'd need do is maybe swap bell housings around for proper starter placement and simply move the hydraulic lines from the right side to the left (clutch slave will be inverted but should still work hopefully).......disappointment on the former.

My existing transmission's bell housing is solid with the rest of the body. The replacement transmission's bell is removable and has the starter placement high on the drivers side...not high on the passenger...this will place it right below the exhaust manifold.

The existing transmission is coming out REGARDLESS. But should there be any problem with the installation of the starter on the drivers side of engine? IE clearance with manifold (which while I'm at it needs a new gasket anyway.

-----------

EDIT: Just pulled my starter (which works perfectly) and turns out it doesn't line up properly with the new tranny's bolt holes (which btw) are non threaded so would otherwise require a bolt and separate nut...but the protrusions on the starter to aid lining up wont let the edge sit flush with the tranny body. Just keeps getting better and better...I've stopped work for now until I can figure out this mess.

Oooookay....good news and bad news.

Good news: I don't have to worry about the starter/clutch slave problem anymore.

Bad news: Bolt pattern isn't quite...right. Got my old one off and finally had the 2 side by side...just the top 2 bolt holes are 1/8th an inch off. This alone is enough to shoot THIS swap down. Took the tranny back...fortunately the guy was amiable enough so I got the 50$ back. He was just as puzzled as me. Actually turns out he got it from a guy who got it from a guy.

Well...looks like I'm going to follow up on that available 4-speed (which I'm dead certain is from a 22R Toyota) and if it turns out that one is a perfect match (I'll either have a bolt pattern made up or have the old one on hand to match directly), I'll then get it for 80$ and install it. Then just stay in the market for a 5-speed but w/o the urgency of this one.
