What T-case?

[TyJ]

First let me explain since I know I could get a ration of it from the real hardcore 4x4 guys.....

I have a 72 Burb that I am restoring and only plan on putting in 4 to go to Tahoe or the Rockies in winter, NO OFF ROAD EVER

I am spendin too much and its gonna be too nice to scratch up, kinda stupid but I do drive the crap out of it

Havin said that I am looking to put in a push button shift T-case and keep my manual hub D44 so I can put in a console(comfort, wife needs a cup holder if she's in the car longer than a few hours, has a trans bump shifter etc.)

I am running a 91 4L80E, I would like to go with a newer T-Case but don't think it will work since they switched from right to left drop in 92-93, anybody know of a reliable one that will work?

Thanks in advance

older np208's and np241's did come passenger drop throughout the 80s and into the early 90s. One of these should fit your 4l80e.

[TyJ]

thanks 1969GMC I'll look into it

Hey guys did some extra research and found out I need a np 243, ( 3 instead of 1 means electric) but can't seem to find out if they ever made a passenger drop (92? 93?) any help would be great
thanks again

I am pretty sure that there was never an electric shift case used in the old right hand drop applications. If it was it would be in an '88 - '91 Blazer or Suburban, but I don't think it was ever offered.

Thanks for the info Blazer I am gonna check with the local truck junkyard tommorrow, I'll let yall know what I find

You could always go with an air shifter...

[TyJ]

Can't really say I know anything about an air shifter in regards to a transfer case

If you don't mind a basic explanation, and would it work with the stock 241 im running now? cost?
Thanks

Could contact Kabuki on Pirate4x4.com. He can probably make you one that will shift your current 241:

WOW that is a trick looking setup- maybe too trick, looks pretty entailed, I will definetly look into this though, I visit pirate a little bit

Thanks a ton Grendel, I've noticed you help out a lot of people here with your vast 4x4 knowledge, want you to know I appreciate it and your service to our great country!!!!

Thanks again

I think it can be done pretty easily, if you have the patience.

You're more than welcome... the more people working on this stuff, the more and better ideas we get, the more inspired I get

[TyJ]

I appreciate your confidence Grendel but one mans pretty easy is another mans extremely difficult, I build houses for a living and although i am fairly mechanical this is just a hobby for me, I try to stay away from custom fabrication of running gear and safety items yet I do tend to get in over my head and not drown somehow. Depending on the price of the unit itself I will probably give it a try, I'll post up some pics If it ever actually happens,

Thanks again

Well, first off you DO NOT want an electric shift transfercase no matter how little you use 4wd or get tired of tripping over the shift lever. And pneumatic systems are very complicated and usually only used on large industrial type trucks. Pneumatics are also $$$$ to swap given the fact you need an air source and all that jazz.

The electric shift units (especially Autotrac) are not reliable and just when you need 4wd the most it won’t be there for you. In fact, that is one of the biggest problems with them is they don’t get used often enough and the encoder motors stick. The fact that they entire system is over engineered and totally unnecessary is another thing (lever’s aren’t that hard to pull people!).

Believe me, I am on my second Tahoe with electric shift and you can’t rely on them! If I keep this Hoe it will get a NP261 someday down the road (it is still in warranty now). Both my 2002 and 2004 Tahoe’s have had warranty work on the electric shift tcases. I also work in this industry and spent a rotation on the GM tech line where we supported dealers when they need help with repairs. I wound up in the drivetrain/chassis group where I took over 30 calls a day with electric shift issues. The system is TERRIBLE!

Also, there was not an electric shift tcase with a right side front output shaft. Even if one existed you would not only need the transfercase you would also need a transfercase control module and a pile of harness that needs input from the VSS and a few other inputs to prevent “Service Transfercase” codes from popping up and the TCCM from locking out shifting. Even with your 6.0L/4L80E swapped in powertrain it would be much more of a hassle than it would be worth to make a huge step backwards to the electric shift.

If you are only planning on using 4 HI once and a while keep the NP205 (I am assuming that is what you have). NP205’s are synchronized for 2HI to 4HI shifts and they do so real easy on the fly if the shift linkages are lubricated properly. The aluminum manual shift transfercases NP208, NP241, NP261, etc are also synchronized to allow shifts in and out of 4HI as well.

Swap in different front seats with a cup holders if that is what is driving you crazy. …it would be much cheaper. The 1999-2006 GM center consoles can be trimmed real easy to allow for a manual shift transfercase if you tweak your shifter a bit or you can shorten your shifter stick and just pop out the cup holder to reach down to the shifter when you need to.

I love technology and am all about retrofitting modern powertrains into older vehicles but the electric shift BS absolutely sucks and you would be crazy to go that route.
