So while at the shop this weekend painting the frame and cab and stuff we pulled the trans to clean it up...and well going back it didn't go so well. The cast lift point on the rear end of the transfer case broke just as we were getting it back into place and the trans fell about 4 feet to the ground and the input shaft snapped and torque converter fell off. Oil went everywhere, curse words were exchanged and fists were nearly flying...you know the drill when something like that happens. Anyways here's the pics.
Broken shaft.
other half of shaft broken inside<br/>
You can see the place it broke on top left of transfercase.
I know very little about transmissions so how much damage do you guys think was done just based on these pictures? How hard of a fix would replacing that input shaft be for someone who's only ever changed the fluids in a trans? Any information would be greatly appreciated!
The broken piece is the stator support shaft. A replacement pump would include that. The input shaft should be able to be pulled out. I'd think you would be able to see any damage done when replacing the pump.

How hard would you say replacing the pump is? I literally have no experience with transmissions. Transmission is out of truck and I'm handing with a wrench but I've never torn into a transmission before. Is it a straight-forward replacement or are there special tools required and/or prior knowledge?
Pump replacement is an easy job. No special tools. One one in the trans will be a little harder to remove without the stator shaft in it but not a big deal.
IF you get brave and try it, I have one bit of advice.... Before removing the pump stand the trans on it's tail with the pump UP (oh, and secure it so it doesn't fall)... If you don't do this all kinds of things are going to find a way to get out of place and cause you MUCH grief....

remove filter first.

after you remove the bolts and if you don't use a slide hammer,do not pry against the back of the pump with a screwdriver against that thin part of the trans!!! if you snap that,the trans is toast!
if you use a short screwdriver to put between the valvebodies and then use that to pry against using a long screwdriver to pry the pump out,that's safe.---and take that with a grain of salt!!!! you've been warned!
+
replace the pump using an F5 casting.ebay reman is ok.
the shaft just pulls out and and can be slid back in at any time,as already stated.that's much easier.
+
with the pump out,it's a good time to split it and mod it for firmer lock up.

Do you guys recommend doing the whole job while it's standing up on its tail? Was going to buy a slide hammer this week to do the job but so you said it's ok to pull the input shaft out prior to starting this job and just slide it back in when the jobs done? Does it have any gears to line up with? Basically what I mean by that is does it have to go back in the same exact way/position it came out? Also the input shaft had a small amount of play in all directions...is that normal?
I was planning on getting a shift kit for it since now I'm tearing into it big time. The link below is the one I was looking at but it was really only the first that popped up. It's the company and type you described so I'm assuming this is the one?
When I say tilt the trans up and do the install I'm saying have the pump end (the end that attaches to the motor) up towards the ceiling and the output end (end driveshaft attaches to) pointed at ground. That shift kit install is terrifying!! lol So many little things that need to be exactly right...Do you remember if you had any play in you input shaft while doing your pump?
Any tips for standing the trans up? I planned on using to big eye bolts and sticking them through these holes and just using the engine hoist to lift it up.
Do you guys think it's ok to do it that way or what would you do? Also here's a pic of inside the torque converter...some light burrs on three of the splines.
I wouldn't even think about reusing the torque converter if it hit the ground, honestly. Especially with the damaged splines. There are a lot of thin fins in there that can be easily damaged.

When I drain the converter would I be able to see any broken fins or have broken pieces fall out? The converter didn't hit too hard it just slid off when the trans was facing nose down.

No, won't be able to see. If the TC didn't take too hard of a hit, it might be OK. Crap shoot.
