With successfully getting the engine and trans out Ive started work on tearing down the transmission to rebuild it. I had hoped to have it completely tore down last night, but I tend to be a bit anal about organizing and labeling things, so that took more time than I wanted. But at least I know where all the bolts and connectors go. I guess for about two and a half hours worth of work I didnt do too bad.

You know, I have to say, Im kinda impressed with the job the filter did. I mean, with all the metal I found in the pan, to say nothing of in the filter itself, I have found not one piece in the transmission itself, including the torque converter. I expected to find more metal in the valve body and channel plate but have found nothing. So had it not been for the damage to the ring gear I could have literally installed a new differential and been back on the road. But what fun would that have been?

Here is a shot with the side cover taken off


Reverse Servo removed (That sucker is a bit scary with the spring pressure on it)



Forward Manual Servo Removed (engages the forward band)



The great thing about putting the transmission on a engine stand is that I can rotate it around about 270* or so. More than enough to make it fairly easy to work on. The only thing I cant do is turn it so that the differential is pointing to the ground, which may become a factor on the re-assembly part.



Here is the bottom (pan side) of the transmission with the 1-2 and 2-3 shift accumulator and the forward apply accumulator



Shift and forward accumulators removed



Here is the valve body, behind it is the channel plate, behind that is the drive chain. I was hoping to get to at least the chain last night, but labeling each of those bolts (according to the manual they are grouped together, so I kept them that way) too quite a bit of time. Additionally the two bolts around the pump shaft are torx bits and were an odd size that in all the sets I had in the garage, none would fit so I had to go out to the storage shed and dig up an old 10+ year old set that I picked up on clearance and it fortunately had one that worked.



Valve Body Removed, Looking at the channel plate



Close up view of the channel plate. If you look close, you'll see a couple of the check balls



Im not going to be personally rebuilding the valve body, Id rather not take the chance of doing all this only to have it thwarted by me doing something wrong with the valve body. So once I get it completely disassembled I'll have it cryo treated and send it with the channel plate off for rebuild. There are several updates that need to be applied to the valve body that require tools that are outrageous in price and beyond what Id want to pay for a personal rebuild. So I'll send those off to Trannyman and let him work his genius on them

Stay tuned, I got more pictures from tonights work but I havent finished processing the images yet

It whines a lot, but I like it.

The only limitation you will ever face in life is yourself!

Nice pictures they were very clear I know it will help other people that want to try it on their own. I found the check balls what do I win???? LOL hehe

Why cryo treat the valve body?

Making you think twice before picking on Impalas

It will help reduce wear from the action of the solenoids mainly. Minor in the overall scheme of things but Im doing everything else in there so I might as well do this too. It will be a flat rate for the tranny so I'll just toss it all in there and have it done.

Well I was thinking more what I would win if you found them, LOL. Maybe rent Dave out to me a week. I'll feed him too. LOL

Well I left off at the channel plate, so we'll pick it up there.

Here is the channel plate



The back side. You can see the 4th gear clutch pack on the right hand side



I pulled out the 4th gear clutch hub shaft and discovered that if the differential had not taken out the tranny, this probably would have in the near future



Here is how the hub fits into the clutch pack



Here is the 4th gear clutches and steels (I forget the correct name). Trannyman, if you see this, can you comment on the condition for me.














Now we can see the drive chain and the drive and driven sprockets


One of the master links


The chain removed



Another view



Im not sure, but the trust washer doesnt look all that good



Disassembled



Now were getting to the innards. By the way, that chain fought me a little on the driven side getting that input shaft to come out. A saws all crossed my mind a couple times.



Dont remember the name but it has to do with the chain set up and trying to get that assembly out of there made me think of a grenade and what a show it would have been putting one in my case and setting it out in the middle of the yard.



This is the second gear clutch assembly and the input clutch assembly


separated



Reverse Reaction carrier thingy (its late, give me some slack)



A close up view for Trannyman to comment on



Yep, were emptying the thing out now



I wrote down the name of this as well but dont ask me what it is right now



Here is the nameless thingy separated out



The following pics are for Trannyman cause there were some gouges in this thing that did not seem normal to me, right above the groove, but hey its my first tranny.









Getting the ring gear out of the case was nothing short of a miracle and made me thing of getting a small thermonuclear device off the black market and letting 'er rip. The manual says 'Grasp and lift straight out'. Well I sure would like to see who they have working on their trannies. When I grabbed it to lift out I was able to pull the tranny around the neighborhood.

I finally had to get a block of wood and a dead blow hammer and pound it out. I didnt get a picture of it, but its the ring gear, its what the differential rides in and is what was chipped when the differential let go and forced my hand on the rebuild


Look ma, theres nothing here




I still got to get the neutral safety switch out and its associated components. Then clean up the case and I think Im going to splurge and have the case and cover powder coated if its not some outrageous expense.

Probably about 6hrs of work and its nearly completely disassembled. I need to get the valve body work done by trannyman and get a single chain set up from him and start putting it all back together.

Oh, Trannyman, I need a ring gear assembly, the final drive input assembly or something like that. Mines obviously toast. I'll have to get some pics up so you can see the damage to it.

I think the disassembly is the easy part. I want to know how it goes together.

BTW, I think the nameless thingy is the reaction set.

Not sure, but maybe this will help you.
