Another 700r4, plus a turbo addition

[Iceman3005]

Turbo 400 transmission cracked due to faulty trans bushing mounts. So going to install a 700r4 overdrive trans, and add a turbo to the 6.2L diesel. Also the inner fender and battery tray are very rusty, so I am going to replace those as well.

Got the manifold on, that was a pain in the butt! Had to jack up the motor, still wasn't much room to work with. Going to try and put the turbo down pipe between the engine and frame rail. I see a lot of people ran the exhaust on the outside of frame rail, but I don't want to have to do that if I can avoid it.

Thanks,I like your posts and like the fact you are very familiar with the cucvs and willing to work on them fairly.When I get ready to regear my 1009 and go 700r4 you will be who I call.I recently stopped at two local shops looking to get estimates on regearing my 1009 and both shops said they would call me and neither did?

Single handedly the person with the most hands on knowledge of the swap.

Yes I can do the 700r4 swap for you. Cost depends on a lot of factors as far as parts are concerned. I highly recommend a new torque converter when doing the swap, other than that all the other parts can be used. Swaps cost right around $1500-1800 give or take, depending on how much the used parts go for. The torque converter is $450 and is rated up to 450 hp, so if you ever add a turbo than you wont have to worry about the torque converter failing. You will also get a new tv-cable. As for the tv cable bracket and rod I suggest we try to find one of ebay or some other source. If I have to make one they cost around $200, it will cost less to find a used one. You will also have torque converter lock-up in overdrive, this is done automatically without any need to flip switches, etc. There will also be a switched installed so you can lock-up torque converter in 2nd and 3rd gears when you are towing. This helps keep the trans cooler, and puts more torque to the wheels.

Not really much I can do, just waiting for parts to arrive. So about the only thing I can do is change the speedometer gear on the transfer case.

Made a little progress on the turbo install, I have been busy with other customer vehicles.

Did you make the turbo hat for intake?

 

[Recovry4x4]

A question if I may. Rebuilders here want $100 more for a rebuild of a 4x4 tranny. Is there more work or more expensive parts or just a way to gouge the off road crowd?

 

[Iceman3005]

There are only 2 differences between a 2 and 4 wheel drive trans. The 2 wheel drive trans has a tail shaft bolted to the back of it, and a longer output shaft. Those are the only differences. If there pulling trans and transfer case, then yes I could see the additional charge for labor. If your pulling trans and taking it to them, then there gouging you. I charge same price for either. My price is based on the master rebuild kit, plus any extras for broken parts, or upgrades.

Partially, I made the drawing and bought the material. Had a welding shop down the road from me do the welds, I wanted the welds to be professional. Not that I can't weld, but all I have is an arc welder and I taught myself how to weld. So sometimes the welds don't look good.

Project is finally going again!! While working on the turbo I noticed the passenger side brake line leaking.............grrr. So I decided to order pre-bent stainless steel lines!

 

[Iceman3005]

Pics of lines!

Were you able to get the down pipe inside of the frame? What size pipe did you use? Post up some photos of the exhaust!

4wd transmissions also have a "K" cast into them around the bellhousing. I know at least on the ones I've seen, the housings were thicker.

But to the original question, yes, $100 is just a gouge. (Unless they're pulling the trans)

Haven't got to the exhaust yet, just installed the transmission today. I wanted the trans and transfer case installed so I could see exactly how to route the exhaust. Have a few odds and ends to finish up, install the fender and battery tray, then finish the turbo oil drain, and lastly the exhaust.

I'm just behind you. Gotta get my trans and t-case in there tomorrow.

What is the ratio of 4th gear on the 700R4? Is it worth swapping in to drop cruising rpm down?

 

[Iceman3005]

.68, drops rpms down to 1900 at 55 vs 2800 with turbo 400.

That is well worth the swap! Guess I'm going to go on the hunt for a good 700R4 and right TQ convertor.
