Tranny Rebuild -Shadetree Mechanic Style

[GeoRoss]

I think you left out the part where they call of the mine to dig up more ore.
Good luck, this is great.

Well, It appears the bearing race is on the slow JUNK from Japan. Dealer said it's TBA, which they interprete as the supplier is making the part.

Well, let's see, since I work for a teir I automotive supplier to Toyota and other customers, the process going sometime like this:

1. Dealer sends signal to TMS is CA for the bearing.
2. CA replies to the dealer that they don't have it. Will give ETA tomorrow.
3. TMS sends signal to TMC for the part.
4. TMC sends order to supplier.
5. Supplier replies that they can send out on 12-12-05. [Original Date]
6. Part not available. Send signal to TMC that part is now TBA.
7. Tier I supplier requests material to tier II supplier.
8. Tier II supplier sends material.
9. Supplier issues Kanban for a production run of specified lot size.
10.Supplier ships out the parts to TMC.
11. Side effect: UPS, Fedex, BlackCat [pick the shipping company] is back logged because of the Xmas effect.
12. TMC ships to TMS.
13. TMS ships to Dealer.
14. Jimmy receives parts. TBA!!

In any case, here are the pics of the valve body disassemble.

Update 12-20-05

Got all the boards disassembled today and they're soaking in the parts tank.

In every hole that accumulated fuild was clutch material at the bottom.
I was not planning of rebuilding the valve body but I'm glad I decided to. I don't want that stuff continuing to circulate throughout the tranny.

The tools you see in the first pic is all one needs for valve body disassemble.
Dental pick
magnetic fingers
1/4 inch drive with 8mm and 10mm sockets
Screwdrivers
needlenose pliers

O- Ali you're funny. As long as she like's TLC's, wheelin and beer. (Order does not matter)

Well, the race came in today. So I had a chance to put all the major components back in the body and check the stackup height.

Pic 1: O/D brake is in the case. This spec is interesting to say the least. At this stage you are checking the thrust clearance of input shaft. In order to get the proper spec, you have to push on the output shaft in the rear of the tranny and push in on the input shaft. (See below pics for illustration) Then, with the dial indicator and extension, pull forward on the input shaft and check spec.

This tolerance is 0.30mm - 0.70mm with max of 0.70mm.

I spec'ed out at .61mm

Pic 2: laying on the saw table you can see the output shaft.

Pic 3: Dial indicator reading.

Pic 3: Installing the overdrive ring assembly.
Pic 4: OD ring in the brake housing.
Pic 5: install overdrive planetary gear, O/D clutch and 1way clutch assembly.

Pic 7: . O/D planetary matting to brake. Now this took some time to do. There are two sets of teeth you have to align, one inner set that you can't see and one outer set that you see. Wiggling back and forth got the assembly's teeth meshed up.

Pic 8: O/D planetary gear in the case

Pic 9: Although I did not take pics of the final tolerance check, I'll explain.
The input shaft (tallest shaft coming out thru the pump) needs to be checked. Same procedure as before, push inward on the output shaft and push inward on the input shaft.
Next, zero the dial indictor and pull out the input shaft.
The tolerance should be between 0.40mm - 0.90mm with max of 0.90mm.
If your out of spec you can shim by adding a spacer. Spacers are .8mm, 1.0mm and 1.4mm.

I spec'ed out right at 0.90mm. I'm okay.

Now I just have to finish up the valve body and I'll be back on the road.



Enjoy.

Great thread. I'm enjoying the pics and descriptions in a big way

Just one question: why do you keep Febreezing your tranny?

Just one question: why do you keep Febreezing your tranny?

Actually, I needed a way to spray ATF on some parts when lubrication was needed. I started off with a washed out pet deodorizing spray bottle, but the combo of that and ATF was a very bad smell.
So the natural choose was to go with that which smells the best in the utility room.

Thanks for following.

Very impressive. Let me know when you get the itch to do a A343.

 

[RavenTai]

I am supprised you have not cleaned the exterior more and painted it.


Thanks for the description and pics, sounds liek you are on the home strech.

 

[IdahoDoug]

Jimmy,

Amazing. You've got "project stamina" beyond belief. As Rick mentions, let us know when you get the urge to rip open a 343 - probably a while after you've got this manly tranny back in action.

Fellas-
Before the accolades go out, I have to test the tranny. It has to shift in all four gears for at least 500 miles. However, I'm confident that I did not miss anything by following the manual and being so anal about cleanliness I should not have a problem.

updated from today on the way.

F*&K, I haven't done any Xmas shopping yet. I guess I'll do it tomorrow.

Update 12-22-05 Valve body and assemble on to the Tranny

Well, I finished up cleaning the valve body and putting it on the tranny today.
Most of the tranny is back together and ready for the pan and bell housing to be mounted to the tranny body. After that's, it's up in the air and mating to the engine.

I was really sceptical about rebuilding the valve body. Everyone I talked to about do it said that they would not touch it. Never a reason why they would not do it, just wouldn't.

Well, after I got everything torn down and cleaned, getting it back together was realy not hard at all. During the cleaning I looked for aluminum fragments from the casting process. I cleaned some loose fragments off and air drying the main bodies very well.

Then, I started inserting the pistons, all the while keeping the piston and body lubed up with AFT for easy assembly.

There are some shims that are very critial in some of the pistons. These shims are there because of the throttle pressure changes.
The 4 valve bodies are like a rat maze for oil passage. The bodies are sandwich in between steel plates with paper gaskets on either side.

For added headaches there are ball bearing that need to go in between the plates.

Enought written, here are the pics.

With 191k on the clock the thought of doing something with the tranny has more than once crossed my mind. After seeing this I have to tell you that finding a used A343 and rebuilding it seems like a good project for this summer. I'll have to go back and find the links to where you got the kit from and start putting some more thought into it.

Update 12-22-05

any more pics.

Look at the A440F filter. Nothing to it, just a metal shell and a fine wire screen.

BTW, the A440F only has one solenoid: Cruise Control.

Enjoy.

THis is great.
