Any one rebuild one of these ? What is the best kit for this (I need Syncros)? Anyone have a picture or where to buy Gm Tool J-29793?
Tore it all down found the bearing in the back is gone (why is the cage plastic?) , one of the syncros is cracked.
The person that worked on this should be shot. He put 80/90 in both the trans and transfer case my feeling it was making noise so he thought thicker oil. Both units have been apart before (Rtv instead of gaskets) but he never changed the U-Joints (still has the plastic in the drive shaft no clips).
Will post pics before I put it in the press lol
This trans will go into the Blazer when its done

Looks to me to be just a metal rod for the 25 dollars I think I will go to home depot and get a dowel
-
Got the rebuilt kit (with syncros) for the trans and also got the transfer case rebuild kit (minus the chain) 300 for both shipped to the house
Hoping to get the trans done by the weekend so I can get it in then do the transfer case.
Thanks Again

We had a death in the family early last week so nothing could be done finally getting back into it. My son has put the clutch back in and the bellhousing is soaking in the cleaner my job of rebuilding the tranny is suppose to be started I have everything broke down and on a scrap piece of copper tubing but am not sure if I remember how it goes lol haynes and chilton are not that descriptive. Hoping by the end of the day to have it back together. Slight problem is the one bolt for the rear trans mount was busted I drilled it and tried a easy out (not that easy) so I got it cherry red without taking it out (the easy out) and that busted in the bolt. I have tried welding a nut on the other side welded a cheap 10 mm socket on it and it wont budge. Not sure if I want to tackle that now or wait till the tranny needs it lol.
-
Trans is now on hold
Over 14 hours between yesterday and today.
All I got done is the Ez out , out I tried a number 5 with a pipe wrench would not budge so I drilled it out and tapped it 3/8 (suppose to be 7/16 but dont think it should be too much problem)
Put the first gear on the main shaft (think it is second gear ) and have been fighting getting the snapring on. there is no holes to put the snap ring pliers and there is two (the same size) I got it to the first slot but now cant get it out to slid down to the second slot. Since its the 4th nothing is now open .
-
Tranny is done ???
I got po'd trying to line the counter gear and thrust washers up I threw the tranny across the room (I was frustrated but it didnt do my shoulder any good)
Of course the case cracked looks like I will buy a rebuilt one I dont have the patience for rebuilding transmissions so I will leave that to the experts.
-
Leave it to the wife ;D
She tells me that I never quit on something before why start now. Grr
I have welded the case (both inside and out) never mig welded Cast Iron lol
Took forever to grind the weld inside the case down.
I poured some solvent on it afterwards and it didnt leak might run another bead on the outside and not grind it flat can still see the crack but no day light or fluid comes thru
in my tantrum I lost one needle bearing and a thrust washer got to call tomorrow and see if the small parts kit comes with it

Frogman, it's only a truck dude. You're going to let something another man made beat you up? If a man made product can kick your ass and you give into it, it's like getting your own ass kicked. Always remember, "it's only a car dude" and walk away. If you can handle your cool in life then you can handle it on a hunk of metal. Get it fixed and get it done. We're here for help...here's an E-beer. Take a chill pill and get back on ity when you're cool.

You are so right Ville (as usual) . I worked on the trans since pretty much Thursday night (The broken rear trans mount bolt. Saturday I was at it till Midnight) and could not get the countergear thrust washers to line up (stay in the slot while I put the gear between em) I got it once had the countergear all in and the front spring clutch (not sure if that is what its called it is what makes the truck select 1st or 2nd gear)slid off and the three pieces went flying so I had to take it apart. Will say the wifes broom made a good tool for the needle bearings in the countergear though she wasnt happy.
-
SUCCESS or so I hope lol
Got the countergear in place got the mainshaft in no needle bearings came out. Have still put the reverse assembly in but the PITA part is done. What I could get done last weekend took only a hour and a half today.
Took the wifes broom and a old flag pole (that is what fit the case and the washer) that is what held the washers in while I put the counter gear in. I left them in till I was putting the shaft in pulled the back one out and feed a ratchet strap under the gear to line up the gear and case I had so much grease holding the needle bearings in that the shaft slid right thru
-
good deal. I just fixed a 5 speed today that the guy couldn't find a used one for under $900 bucks. I fixed it for $36 lol Patience Danielson.

Same thing around here. they wanted 450 for the trans and no guarantee it was any good as the idiot told me "how do we know you aint bring us your bad one" which I responded I know you mark your parts so for 200 (150 for the kit with the syncro's and 50 for the small parts kit) I should have a great transmission lol
-
I am about in tears (not really but po'd) again
Put the trans together just to see that its good and to see how to line up the shift forks before I go to putting gaskets on
It wont shift its frozen it is taking alot of effort to turn the trans so I go and look at my pics and find I put the rear one (the one with a gear on it) in backwards in the pic its the one on the right. I now have to unassemble the trans plus unpress the rear bearing off I am not looking forward to this not sure how I screwed it up since I assembled it with the pics plus I had every thing on a piece of pipe.
(http://i239.photobucket.com/albums/ff310/frogman1968/DSCF1331.jpg)
Got it out in less than 30 minutes I am getting to good at this trans
(http://i239.photobucket.com/albums/ff310/frogman1968/wrong.jpg)
And another 30 minutes to make it right
(http://i239.photobucket.com/albums/ff310/frogman1968/right.jpg)
Lets hope it only take 30 minutes to put it back together
-
well about a hour and half got it back together and still not shifting took the side cover off 3 and 4 gear selector (part were the linkage fork goes on the mainshaft) slides freely 1 and 2 wont budge (this is the one that had the broken syncro) looking at it seems that the gear needs to come down another 1/2 inch or so but when I had it in the press (20 ton) my 160 lbs on the handle would not move it so I thought it was all the way down. I have quit for the night with some jack and coke and will try and look at it with fresh eyes tomorrow.
Any one have any ideas what I am doing wrong ?
-
Grasshopper, be one with transmission! lol
-
I have lost count how many times I put this thing together put here I am and another wasted weekend on this trans.
I have everything together but once I put the side cover on the linkage wont move not sure why the spring clutches move freely when the side cover is off and the linkage moves free when its not on the trans I am at a complete loss.
-
Don't look at it as a waste of time. It's a good learning experience for you. Soak everything with penetrating oil.
google MY6 and a833 overhaul. You'll find some tips
-
After another futile day of putting it together and taking it apart I am at the point of starting from scratch tear down the whole main shaft again. Making sure everything is correct and putting it together one last time. If it still dont work I will look into getting a rebuilt one. Reason is the tranny was locked into 2nd gear when I pulled it and the linkage wouldnt budge. That is when I found the broken syncro and the bad rear case bearing. I am starting to think something might be bent and unrepairable (Ie the main shaft).
-
Houston think we have a problem.
Took the main shaft apart was checking ever thing and the spring forward clutch (for 1st and 2nd gear #48 in Haynes and Chilton's diagram for the 89mm trans) does not slid freely I must force it, again this is the one with the broken syncro. I took it apart to see if I turned it would it go freely no go on that. Thinking of taking a file to it but there is a ton of keys to go thru a replacement one is 216 dollars. Might just go with a rebuilt one and put this one back together as the core.
Side note the 3rd and OD one slides on and off with no pressure
-
Try filing it.
-
Try filing it.
Filed the teeth down (it was only the bottom part that was chewed up) didnt make it perfect it was getting a little sloppy on the top half of travel.
Have it all back together. Is it me just be stupid or does this sound like something is still wrong.
I cant turn the trans by hand and cannot move the shift levers except reverse ?
Drivetrain.com has this trans for 1050 little more than I would like to spend . Would you slap everything back in the truck and give it a go? Before I spend that type of money I would love to be sure lol.
Edit:
Got the trans to move now. Took the old clutch plate put it on the splines then put a pipe wrench on it and whacked it with a BFH it now moves freely time to put the side cover on and see if it will shift.. Not sure what was jammed but its free now no loud noises when it broke free lol
-
Well it shifted had to move the shaft a little to get it to go 3-4 was smooth 1-2 was a little tight I thought it would wear itself to the other half. Its all moot now started putting the gaskets in got the front done . Took some time to get the side cover on made sure it was squeezing the permatex out since Chris stated this tranny is a known leaker. Starting going in a star type pattern heard a creaking noise look at it , it was still against the case. Was looking around and that is when I saw the case cover is cracked. The one part I have not thrown cracks not sure if its white metal or aluminum . This trans has been a jinx since I started going to snug the bolts up and call for a new one in the morning. See if I can find it cheaper than a grand.

If this trans doesn't work out for oyu why don't you convert to an automatic?

This is the parts truck to make the Blazer a stick, just was using it to teach my son how to drive a stick
-
Well I found the trans
Rebuilt with a 1 year unlimited mile warranty.
595 +130 to ship (and for me to ship them the core)
Should be here in 6 business days (which is good since we are going away this weekend)
-
that isn't that bad if it is a quality rebuild.

I was going to post the link but didnt know if it was allowed.
A manual trans in my eyes hardly ever go bad so with in a year I should know if its a quality build
-
You can post it.

You can post it.
Here it is :)

Got a email from them already (so far Chris they seem to have your stores etiquette) there was two diffrent A833's used in these years I had to measure the height from the bottom of the trans mount foot to the top of a cast they sent me a pic to show me what to measure pretty cool
-
Ok since I am this far I decided to get a good set of tranny mounts
Summit lists only these but say automatic only I checked Energy Suspensions site and it doesnt say they look right but for 55 bucks I want to be sure lol (After I spent the money for the rebuild and for the rebuilt tranny)
