Id go back and put the hard word on the $85 mechanic.

Ask him again to his face what his dianosis was. Then show him the recipt and hold your hand out.

I have owned this truck now for the third week and it has been quite an adventure. This truck had me at hello. I forked over the $1500 without even test driving it. The body was in pristine condition and the speedo shows 46,000 miles.

I still had the number of the guy who sold it to me. I called him last night after finding the receipt about the repair work and finally asked him some questions. He said the truck belonged to his brother who was recently deceased and he sold it cause he didn't want the memory. He said those are original miles on the truck. He also said everything is original except the rebuilt tranny.

He then said to me, "Do you want to sell the truck back to me? I will give you back your $1500"

I declined. I will post some pictures so you guys can see how clean it is.

I am driving a dead mans truck, but then again many you of guys are probably driving a truck that has a deceased previous owner.

Hey there. I'm SlugLUV's buddy. We spent the better part of the afternoon getting the truck up on ramps and pulling the driveshaft out off the tranny. If not for the Haynes manual and the guidance in this thread, we would've had a vague idea of how to get started. Here's the photo documentation of how it went down.

First, after getting the driveshaft off the rear end, and pulling it from the tranny, we noticed something wasn't right. It was a real bitch to get off, as if it was fused in there. Also, no oil leaked out, as the manual warned it should. Then as we looked around the tranny, we noticed quite a bit of fresh oil spray.



Uh-oh. We kept yanking on it, and were greeted with this gem:



Well that doesn't look good. Remember earlier my buddy mentioned the mechanic let slip something about a bushing? There it is, the source of all the trouble it appears.



The bushing appears warped and deformed from heat and friction, and was preventing the shaft from sliding right out. We had to pry it out with pliers, then had at the driveshaft for about half an hour before it finally came free.



Ugh, what a sad sight. What the hell is this thing, anyway? It doesn't look like what should be in the Haynes manual:



Piece #32 is the "oil seal", which I don't think was even there. It appears to be a metal ring with rubber on the inside. Unless, in one of the rings there was rubber, which burned off, but I doubt it.

Why were all these pieces in there?



We ended up with two rings and two bushings, where the manual says there should be only 1 of each. What did these guys do? I'm thinking they didn't have the correct parts, and just shoved whatever in there.

Also, we got this piece, which I don't think was meant to be a piece at all:



Haha. I don't think this was meant to come off like that. Look where it came from:



Crap. I think you really need that at the end of the tranny. What do we do now?



Well here's the driveshaft. Think it's still in good shape?



There is it, the LUV. My buddy made a great find. Original paint in near mint condition, 46k original miles. It looks like it was garaged and babied.

So, here is our theory of what happened:

1) Rebuilt tranny was installed.
2) Driveshaft to tranny installation was done incorrectly. Two many and/or incorrect parts.
3) The parts failed, the tranny oil leaked out, causing all the vibration.

I can't believe the mechanic was looking to screw him like this. This should've been a simple diagnosis for him to make. Instead off the bat he says new tranny, clutch, blah blah, with inflated prices. I think he saw what he believed to be a young and naive man with a real cherry truck, hoping to make a big score. "Yeah, your truck is toast...but uh, what are you planning to do with it now? Can't make the repairs? You know, I could take it off your hands..." Unbelievable.

So what now guys? That broken off tranny piece is our main prob now. In the Haynes manual it says the end of the tranny, "extension housing assembly", which the piece was on, should be removable. Could we just get this piece, and install it on the tranny? Does the whole tranny need to come out to do this?

And after we do all this, I'm hoping this was really the sole source of the trouble. What do you think?

We're anxiously awaiting to hear from you. Thanks for all your help.

I think you need to go back to the guy that put in that trans. That drive shaft has seen some high heat. You can tell buy all the blue/purple color on the end.
I think the shaft is ok, but the trans was rebuilt wrong and might now be destroyed. Those parts that fell out probably belong in the trans., and they broke and are taking the back exit. With no oil in the trans, it has seen very high heat also, I think your probs. are in your trans.

Now the guy that gave you the estimate IMHO wasn't far off. If the trans. is bad, and you have to take it out, that's also the best time to install a new clutch and release bearing, and the bla bla bla. Because the bla blas only cost about 12 bucks each. And it really sucks to pull the trans out later just to replace a $12 bla bla.

And for $450 that first guy probably only did a trans. and not any bla blas.

OK, I'm over it. Where's the beer?

Yeah after looking over the Haynes manual and removing the drive shaft maybe the mechanic is right. The only thing he is guilty of is that he was going to deprive me the satisfaction of fixing it myself.

I am already scouring CL for a cherry picker and looking over the removal of the motor and engine unit in the Haynes manual.

I have my buddy to help me but the only thing we know how to build and disassemble is personal computers. We have never removed an engine before, nevertheless fix a tranny or install a clutch.

I am going to spend the money on tools as someone suggested and a years supply of GOJO

Thanks everyone for all the good advice.

Im sorta with rondog.


Thats bits youve got are a bit of a mystery. One looks like its a speedy sleve. They are used to space a worn shaft up to the next size so that a seal has a nice unworn surface to work on.


It is possible that youve had 2 of #33 and one has clashed with the other and disentergrated the back of the box.
The back of the box is knackered, theres nowhere for the seal to go.


Is there oil in the box????


Stick the tailshaft back in with all the dammaged bit out of the way and see how it feels. Is it still nice and tight up and down and side to side???
You could search for another box for parts and swap the rear housings over if your box still feels OK. Its not a hard thing to do.


Or swap in a used box. Id chase up that box guy in the invoice tell him the guy was your great uncle or something. lol.

If the clutch was ok and not slipping etc i wouldnt touch it. Once youve had the box in and out a few times changing a clutch can be all over and done with by lunch time.

I wouldnt pull the motor out. You can take the box out buy itself from underneath. Well you can on a 79 whats yours as 73 isnt it??? Not sure on one of them.
Undo it all and pull it backwards up over the x-member at the rear and then nose dive it down at the front.


Cars are sorta like computers, they are made up of bits. One main difference is that unlike computers, chances are it was all the cars fault not the user.
And you only have to worry about static when your gettion out of your truck wearing nylon undies.



And my truck came from a dead guy. I bought it off a guy up the road from the old guy, he bought it at the clearing auction after the old guy croaked it. Its got real low miles too, cant rememebr how many. Its had a pretty hard farm life. The cab is not too bad for rust but the style side is nearly a write-off. The motor is as sweet as a nut.


Cheers, Bob.

Sounds to me like you should just shop around for a decent used transmission and drop yours out from underneath and swap them out. Whatever came loose in your transmission that caused a serious enough problem to tear the dickens out of the tail shaft housing and get things hot enough to discolor them just aint good news at all. Tearing into it to try to fix it could just open up a big hole in your finances.

Hang in there though - and least you guys are mannin' up and jumping in there to sort it all out. A lot of guys would just whine like hell and sell it at this point.

If you go to http://car-part.com/ you will hopefully find a lot of transmissions that fit your truck pretty cheap ($100-$200) and most junkyards will ship it to you if necessary. Also do a thorough search on ebay - there are transmissions that fit your truck there from time to time too.

What you need is a transmission that fits a 72-75 Chevy Luv ONLY - because after 75 they changed the engine design and the newer transmissions won't bolt up to your engine at all. Just make sure you replace the front and rear seal and you drain the transmission and refill it with fresh clean 30 wt motor oil before you put the new transmission in and you should be OK.

Good luck!

you can pull the trans with out pulling the motor i did it and if you need a trans i have one in my other 75 luv i am not going to use the motor/trans i have not drove it to see if it run but the guy i got it from said it ran when he parked it so if you wont one or both i sell trans 150.00 or both for 250.00 they are still in the truck i hope you don't need it but if you do ok you guys are doing a great job if i was a bit closer i'd luv to help you all out i am a truck guru but i suck at computers lol

FIAA!

SFPP!

For a replacement trans you can also use the trans from a diesel powered 2x4 Luv or pup. You need one from behind a C190 engine, commonly 4 speed, or a C223, again commonly 4 speed or a C223-Turbo which arent real common but is likely to be a 5 speed.

Ive never seen the starter motor on a C190 i would imagine yours will work. For the C223-T they had a reduction starter and you have to use one of this type as the little dome in the bellhousing for the nose of the starter is too small for a regular starter.


Cheers, Bob.
