Time to see what went wrong.....

OK then, so back apart it comes......

Oh no! it's missing some guts!



Reverse input clutch assembly.... Still looks brand new........



3-4 clutch pack assembly.......... still looks brand new......



Forward clutch assembly with forward clutch sprag......... still looks brand new.....



Overrun clutch assembly......... Hmmmmmm....... Notice anything funny?



Overrun clutch assembly spread out as much as possible........... Notice anything odd?



That's as far apart as it will come........ the 2 friction discs burned up and welded themselves firmly to one of the steel plates........ Not sure how I screwed up but that's the result of it.........

More new parts on the way.......



Just in-case anyone's ever wondered how many tools it takes to remove/re-install a transmission/transfer case assembly under a 1989 4x4 Suburban..... (screw-driver can be substituted with a small pry-bar) (transmission jack not pictured......)

Transmission

Well, before I started taking the transmission back out I thought I'd take the finished pics I was going to before it messed up.

New external trans filter, and the new pan.



Dropped the pan............... This doesn't look to good.........

Transmission

We'll...... looks like trans is coming back out tomorrow...... (just cuz I don't feel like doing it today......)

Transmission's in

Well I got in and all hooked up yesterday. Got my external filter all plumbed up and mounted today. Decided to try and run it a little while still on the jack stands to try and find any problems before actually road-testing it. Looks like it's a good thing I did........ First it seemed like things were OK, then heard a clunk so shut everything down to make sure nothing broke that I could tell from the outside. Everything looks good.... OK then, so started it back up and darned if reverse don't work now and the wheels turn like it's in drive when it's in neutral......... According to the book, both symptoms have the same common problem....... The forward clutch not disengaging. After going over my ATSG book and my FSM (that just happened to come in the mail today while i'm out working on it) I'm thinking (hoping) it's just a stuck valve in the aux. valve body keeping the forward clutch engaged. The valve I think the problem may be moves one way in LO and the other way in Reverse......... So tomorrow i'm dropping the pan and the aux. valve body to see if that valve is stuck............ So hopefully road-test tomorrow...........

Transmission Rebuild DONE!!

YAY!! The rebuild is done!!

New servo assembly.......



Now just have to swap it back out.....

Transmission Rebuild cont.

Well i'm still working on it........ It's getting there though.....



Woo Hoo pretty much done!! Finally!!

(just have to wait on the servo pin to get here...... since I broke the add on tip that came with my kit...........)




Ooooooo new torque converter......

Transmission Rebuild cont.

Yay! finally got it completely apart!!!



Some things are ready to go back in now....



Now it looks like it did this morning....... Except it's already going back together.......



Now all that's left is to rebuild the input drum assembly and finish putting it back together.

Custom tools worked good so far.....

Transmission Rebuild cont. Custom tool time!

Well all I got done today was building a couple of custom clutch pack spring compressors. Not bad for a few hours work with a drill, welder, 3" cutoff tool, a pair of aviation snips, a hammer, and a couple of files huh?

(just ignore my crappy looking welds)



So now tomorrow I should just be able to job out and get the clutch packs done........ Hopefully....

Transmission Rebuild cont.

Not too much to report on today. Just finished up the valve train and got the pump all cleaned up and rebuilt.


Check out the gap on this clutch pack!!!



No wonder this transmission didn't work except for first and reverse..........

Time to build some custom tools now.....

Transmission Rebuild cont.

Well i'm well into my first transmission rebuild now......

(Sorry about the lack of pics during actual disassembly but messy hands aren't good on camera's so this is at the end of day)

It's mostly apart now....



Though some things are already put together ready to go back in when the time comes...



Well well, what have we here....... Yep Just as I suspected, the band is just about completely burnt up......



Here's what it's supposed to look like. (Or rather here's what a new better one looks like)



Here's the 2-4 Servo assembly......

Old one.... (without the pin because I already assembled it into the new one)



New one...... ooooooo shiny.....



New one on the left, old on the right....



(I just realized I didn't take a pic of the new torque converter that came with my kit.......... D'OH!!)

Oh yeah..... External filter kit is on the way too...

Yay Parts!

Lookie lookie what the nice UPS guy left for me today......

Wrong pan but we'll get that sorted out in the morning.....

Transmission Rebuild

Well, While i'm waiting on the rebuild kit to be delivered I decided today to start cleaning up the case and start the long draining process. (Pay no attention to the mess in the background.......)


Here's what I found when I removed the pan. (pay no attention to the gasket in it)


Looks like somethings burnt up pretty good........

Could this be the reason? This is what I found after removing the filter.


2 seals............hmmmm...........

Transmission Rebuild

Well I ordered a rebuild kit for the transmission today to rebuild the one I pulled out. So now I get to try my hand at rebuilding an automatic transmission....... yay........ I guess we'll see how it goes after everything comes in.........

Transmission's in

Got the transmission all hooked up today and test drove it. It works better than the one I took out, but this one's not wanting to shift into 3rd...........

Guess I need to get the one I took out rebuilt sooner than I had hoped to do it.........

Transmission

Well, started swapping the transmission out today. Got the old one out and the new one in but not hooked up yet. Would have finished today if I hadn't broke the plastic end on the T/V cable unhooking it. So had to go to the dealer and order a new one (since apparently it's a dealer only item), it's supposed to be in tomorrow morning. I would have hooked up everything else and had it ready to go as soon as I got picked up the cable, but I just lost all motivation (beyond actually hanging it under the truck) to finish it up today after I broke that. So hopefully i'll be able to road test it tomorrow (only around my neighborhood since it doesen't have current tags or insurance yet) after get it all hooked up and change the filter/fluid.

After getting the old transmission out it looks like it's a rebuilt one already........... about to be rebuilt a 2nd time?........
