I've had a trans sitting here for nearly a year, got a good deal on it and figured I'd get to it some day. Well, today was that day.

Got it mounted on the stand and started removing the side cover.


Got all the bolts out.


Before removing the cover I flipped it and removed the diff cover.


Comes off easy enough.


One HD diff.


Comes out easy too, output shaft came with it, I think that was to go out the other way.


And on the bench with it.


Removing sprockets.


Pulling the shaft.


Flip t back over and remove the cover


Here'* the innards Sensors, and valve body


Removing the wiring harness.


Pulled the pressure switch.


Now off with the oil pump.


And finally the valve body.


Now we have the gears.


4th gear clutch


Hmm, what have we hear? a trans from a 98 with a 4th gear clutch shaft with 09/27/04 date on it. Looks like this trans has been repaired with a new hardened clutch shaft.


Removing more parts.


Input clutch drum


A band


I just keep pulling more parts out.


See, it'* like magic.


Reverse Reaction Shell


Another band.


It'* the last one, I swear.


Flip the trans over again to remove the pan.


Chris showed up to change his thermostat.


So much easier then when your laying under the car.


Last of the parts


Now that is a big pile of parts.


Taking it apart was easy, now to put it back together.

yup the fun part is always putting it back together good thing you took pictures

And I have a very detailed manual on rebuilding transmissions.

Go, Dan, go! I'm dying to do an automatic, and since mine is nearing 200K I'm thinking of buying a donor to rebuild before mine goes.

It'* really not all that hard. Having the engine stand and the bracket I made, thanks to billboost for that idea, and a few tools, it'* rather a easy job. Get a trans service manual, big help there. Just wear rubber gloves and keep everything real clean. I plan to put this one back together, then rip it down again, and do this several times.

Not bad! I could give myself a new transmission, if I only I had the: space, stand, tools, manual, donor transmission, jack stands, lift…

Best of luck on your rebuild!

Well, best to start a list.

Sure. Here'* the condensed version:

• BillBoost'* garage
• Contents of BillBoost'* garage.

Someday, but not today.

good list
now can you make it happen without bill thinking that your taking over?

Dan, when you rebuild this trans, make sure that you tighten the clutch clearance in the 2nd and 3rd clutch. GM does not give a spec for this, but we use 1 or 2 oversized steels for the 2nd clutch and use a few early 440-T4 3rd clutches to tighten things up in the 3rd clutch.
