700r4 conversion

[bryancarson]

New to site, have an M1028 new to me this year. I am doing my 700r4 conversion this week, wish me luck!

I have one in my M1010 and love it, good luck.

Had one in my old 87, tuned port, trans am. That transmission took a lot of abuse..

Good luck and Welcome.

Good luck. Do you have all your parts sourced?

Kenny, is there a sticky on the complete list of parts required? I want to do my 1008 before my old Dodge diesel finally dies so I have a set of wheels that goes faster than 45. John T

There is not that I can think of John but I think I can scribble something down here in a minute or two that gets you real close. Please forgive my lack of the ability to space paragraphs. There is something with this network computer settings that prevents it. 1) Transmission. Make sure it's a decent quality rebuild. The 700R4 from a diesel uses a different governor so instruct your rebuilder accordingly. Also make sure it's a "K" case. These have a few differences for dealing with transfer case weight. 2) Either a TO transfer case or the 27 spine input gear for your existing case. The case on the turbo 400 is 32 spline. 3) Adapter. There are 2 distinctly different adapters. The long one is the correct one but if all you have is short, a spacer can be fabbed up. 4) Diesel throttle valve (TV) cable. It's much shorter than the gasser one. 5) New flex plate. Trust me, they are different. 6) New or reman torque converter. If you want a warranty from the rebuilder of the tranny, you will need one of these. 7) TV linkage. This piece is the holy grail of the swap. Long out of production, you have to scrounge to get one or check out Ebay. Expect to pay $100 or so on there for one. Torque converter lockup controls. Many available, check with your rebuilder on which one will work with your trans. Most everything else is nickel and dime stuff. Your existing crossmember will work as will the driveshafts. Factory shifter will work as well but if you want to see OD, you will need to change the shift legend. Not a difficult swap if you are prepared going in!

Good to know. I just got in two junkers, both with diesel specific 700 setups. Both have the TV brackets

I went with a 700r4 out of an 1989 2500 4x4 that was behind a 6.2 K case $250 (had to drive to Traverse City to get it) came with torque convertor, picked up the flex plate also. Advanced adapters th400 to 700r4 kit did this because its supposed to retain th400 length and I had just had the drive shaft retubed balanced with new U joints. OD lock up kit from TCI, Transmission cooler from Derale. Originally intended to rebuild the unit myself (bought the how to CD) but met with the local tranny guy (who seemed to know his way around a 700r4) and for $480 he rebuilt it. New TV cable from LMC. The bracket I'm nervous about got that from LMC stated in the catalog it was the proper TV cable bracket but when it came in the mail it had edelbrock printed all over it? So hopefully its the same? Using Royal Purple max ATF hoping it will keep it cooler as they advertise. Think that's about it.

If you scroll through this thread, you will see pics of the necesaary TV linkage. The Edelbrock stuff isn't going to work without extensive mods and some fabwork.

Welcome from "broke outta mulla" Illinois. Keep us informed on the swap.

If anyone is looking for parts please start a WTB thread in the classifieds. The open forums are not the place to buy or sell items.

 

[bryancarson]

Thank you for your input Warthog. I did not intend to post or request parts in this forum, my intention was simply to ascertain whether 2 6.2L diesels that I have in my friends pole barn would have the proper throttle valve cable bracket. I will have to reread my posts in the future to ensure this does not happen again. Once again I apologize as it was not my intention to request or offer parts in this forum just have a question answered.

FWIW one of those 6.2 700R4 thingies just popped up on a popular site. It has a proud owner.

 

[bryancarson]

Finished!! 700r4 in, 500 miles on it, the only thing I noticed was shift from 1st to 2nd chirps the tires. First tank mixed traffic highway and city 19.2mpg, second tank all highway 22.7mpg. She now has now problem cruising at 75 with a low rumble instead the scream at 60 (did increase tire size to 33). So far I'm HAPPY!

 

[m38inmaine]

Mine also shifts"hard" 1-2, as you get use to it you can improve the shift by how much fuel you give it on take off.

 

[Recovry4x4]

You can thank that little bark on the 3.06 first gear. Really helps get the truck moving.

 

[bryancarson]

Gotta thank all of those before me for the countless tips on the 700r4 conversion and the starter relay conversion, I drive down the road at high speed with a HUGE grin on my face now! When I first entered the military the cucv's were just beginning to be phased out (2001) always loved them. Thanks to everyone who's post I've read and owe a huge debt of gratitude too.

 

[bryancarson]

Ok, I have a couple of gas tachometers laying around and read some where that you can run them thru the alternator? Has anyone done this on their cucv? Is there some kind of conversion to the signal that needs to be done?
