Any info on how to remove transfer case from tranny

[Mohpar]

Looks like I have to remove the t-case and OD unit to install the rest of the springs for my shift kit.

I think I have to remove both driveshafts, but does the tcase just unbolt from the trans?

Any diagrams or videos would be great, or just explanations

 

[Mohpar]

Anyone ?

It will just unbolt. Are you having trouble getting it off of there? It has been a while but I think there are just 6 or so nuts holding it on.

What kind of shift kit requires all that ****?
I would so not bother.
But I work hard all week I'm lazy on time off.

Ok, I want a kit. Please tell me you just have some weird ass **** and this isn't normal.

Talk to Lifted01 before you do that. It shouldnt require that because he has the Dane kit i think and he didn't drop the t case

You don't have to drop anything besides the transmission pan and valvebody. I'm not trying to be a **** but did you read all of my write up? The shift kit deals directly with the internals of the valvebody and a few springs for the front and rear band that's all. Nothing with the transfer case.

Well it's not anything weird I think. It's just in the instructions it detailed that you had to slid the OD unit off, and it seems the get that off I have to remove the Tcase too? I'm new to transmission work so you'll have to bear with me. If I had the money I'd just have someone do it, not worth the time and learning curve, and worry it has caused. Unless you like learning new things about your truck and like to DIY.

That's not being a ****, I understand. I didn't read it initially, busy with school etc. The thing I don't get in your writeup is regarding the rear band. You said there is a "finger" that holds the spring assembly for the front band where the upgraded spring needs to go. C-clamp the piston assembly and remove the finger (attached to the bands) the holds the assembly. But what about the rear? I should have taken pictures, now I'm forgetting what it looked like, but I think the transgo instructions said to remove a servo pin, accessed only by removing the OD unit back, thus why I thought the transfer case needed to be moved as well.

I know my way around an engine, but my transmission has been a learning experience for sure.

I never messed with anything for that o/d unit. There was one spring I left out because it would make you manually shift your transmission or something and I didn't want that option so I left it out. Unfortunately I never could find the picture I took of finger but if you look at the front band you can see what holds it on there. I'm trying my best right now to remember everything lol

Okay... I included some instructional pictures mabe that'll help. Do you remember installing the tapered orifice ? Seen in step 2. Just seems my pressures are off and I can't figure out why - I thought it was because I didn't install the orifice and springs.

Yes please Merc...from what I understand, put a jack under the trans, remove skid plate and cross member, and pull the linkages and sensors off the Tcase. Then unbolt and slid the OD unit off/back?



I hope the pictures are showing up

231D T Case Removal

Fast and Dirty Diy

Set up a jack and using a 2x4 between it and the tranny pan just take a bit of weight off the trany, next undo both 15mm lower mount bolts, loosen off the two upper 15mm bolts, ok jack up the tranny just until you can get the mount out by twisting it over, lower the tranny until the fan just hits the shroud, keep an eye and ear open on the exhaust system, remove the vac line from the front top of the t case mark it first using a paint pen, remove the speedo wiring plug, remove the shift linage at the end of your choice, figure out how you plan to support the t case now, ok undo all the 6 nutz around the t case to tranny top first, pull the t case back and down.
Reads ez and it is, I would put the skid plate back in to help you out.

Insert liability waver here.

No I never installed a tapered pin at all. Those instructions are different from mine, atleast the first set. I never got any of those deals or a tapered pin. Which is sorta concerning, if the kit is some what different that doesn't help me help you. There's a few things springs I never used and I already threw my kit away. I used the new spring for the second servo but not for rear since it makes the trans manual up shifting.

Thanks good writeup. I'll utilize it if I do pull the Tcase.

So in the instructions it says. for the rear servo parts, to install only if don't manually upshift from 1-2-D -or- drilled a specific hole .093 or smaller in the valvebody. I also don't really upshift because I'm afraid of breaking the column shifter This said, I'm considering not doing the rear servo parts, and I didn't make the hole bigger than .093. Basically what I'm saying is I might just skip the rear servo parts, and install the front, adjust the bands, and see how she's looking. If it's not doing well then I'll spend yet another weekend installing the rear servo parts.

Oh what a project.

I also never installed the shift kit into my valvebody either. I had a guy at my work do that for me, he's been a transmission guy for over 25 years. I don't recall him drilling that hole any bigger. I'd say skip the rear servo springs and just run with the rest of the plan. My truck never acted any different with leaving the rear servo alone. One thing I never did was adjust bands, I've only heard guys doing that and burning up their transmissions later on sooner than expected. Good luck finishing her up.

Interesting. It does say in the instructions to adjust them though...and the way it's shifting I think it needs it. I'll talk to TransGo and see...

If you talk with them post what they tell you. I called them once about the rear servo but that's it. I just didn't want to push my luck adjusting the bands.

I'll update for sure. I've already talked to them about 5 times asking questions during the shift kit install. Having someone else do it is a great idea, you lucked out there.

Yeah I did. The guy I had do it used to be a transmission tech for about 25 years and still does it as a side job.
