M1008 700R4 swap question

[Dieselsmoke]

Never thought I would do it, but now that I have multiple M1008s and a free 700R4 I'm gonna. So for those who have done the swap, what did you do for the gear indicator now that it has an OD spot?
Pretty sure I have everything I need ,TV cable & bracket, just wondering what to do on the gear indicator.

Junkyard chevy with OD

if you cant find one, i will swap you an od for a regular 3 speed one

Talk to Croatan Kid and mangus. They and a few others on here have done the swap. If you can find a whole truck with the 700R4 (preferably a diesel) then you have all the necessary parts right there. However be aware the 6.2L 700R4's are set up a bit differently than the SBC 700R4's.

Just find any proper bodystyle Chevy truck/Suburban/Blazer in the junkyard and pull the indicator from its cluster. It is only held on by two bolts and is a direct swap.

Later,
Joe

I never bothered with my indicator.... I do have a replacement too.

The donor truck was a '91 1 ton, so the dash wasn't the same. Didn't realize until today that our body style was ever offered with OD, but was fortunate enough to find one in a buddies wrecking yard. So now I'm complete, ready to swap over...now I just need time.

 

[AJMBLAZER]

It was. Half tons and some 3/4 tons got the 700R4 in the 80's and in 1991 the crew cab 1 tons of our style got a 4L80E with a remote controller.

 

[Croatan_Kid]

I never bothered with mine.


The only aggravating thing is since it was originally a 3 spd, you can't pull it manually into 1st gear and hold it there.

 

[AJMBLAZER]

There's a way to adjust that...I know the guys on CK5 have done it.

 

[Croatan_Kid]

I don't really care now (although, a few months ago that would have been nice info!) since I'm putting the Cummins and NV4500 in it.

Did a bit of searching on here but I was wondering, what exactly is needed to do this swap in a 1008? Will a 700 from a 4x4 gas truck bolt in? what about crossmember, linkage, driveshafts? I do not have a donor truck with a diesel but I do have one with a 350 sbc.

Thanks

Hmmm I'm not sure why you couldnt find it, as I have listed it probably 3 times.

A gas one will work, but you will need to have a tranny shop make some 'adjustments' Ideally, you would have it rebuilt to be used behind the diesel.

Also, you will still need a bracket from a diesel for the TV cable.

Not to distract you from the question you posed...
But are you swapping in a 4L60E, 4L80E or a 700R4? The E designation on the two are for "Electronic".... as in computer controlled. Are you swapping in the computer as well?

Here is a link that I found that sells rebuild kits. PATC rebuilds some serious high HP withstanding transmissions. 700R4, 700 Raptor Transmission from PATC, 700R4 4L60E 48RE 4L80E

It's all a direct swap except you need a different spline on the transfer case input, usually just swapping the whole transfer case is easier and cheaper.

Anyway, a 4x4 TH400 and 700R4 are the same length and the crossmember and both driveshafts work just fine. All the linkages fit in the same places and even the transmission cooler lines will work, you just gotta give them a gentle bend by hand to get them to fit up into position.

If anybody needs a good 700R4 and matching transfer case for an M1008, I just pulled mine a few weeks ago and it's only got about 10,000 miles on it. Has a problem going into reverse when it's cold, but when it warms up it's fine.
