Adapter plate for 700R4 - TurboTim - 10-23-2014
Anyone used one of those adapter plates for a 700R4? My trans is starting to slip and I like the idea of the lower 1st gear and the fact that you can get a built transmission for very cheap, so cheap that it makes the price of a adapter plate irrelevant. Its going in a W126

I think the 700R4 would be an excellent trans for the diesels. The only problem I see is the size, mainly of the bellhousing, which looks a bit larger than the Merc one. I asked the guy that makes the plate and he had never heard on one being installed in the original Mercedes car, they had all been used on transplants.
I'm sure it can be done the only question is how much effort will it take?

Hope this helps, om617 to 700r4

Evenglass, how do you like this trans mated to the 617? What rig did you mount it in?

1996 Cherokee. You can see my build here;

The 700r4 is perfect for this engine with some exceptions. The stall must be kept high enough for the engine to build power, the 1800 stall I have in now is stalling right at 1600 and this is far to low. I'm in the process of installing a custom converter that should stall around 2200. And secondly the one-two shift is very harsh, in my case its because my transmission builder replaced the one-two accumulator spring with a stiffer one. I'm replacing this spring with the factory "red" spring when I do the torque converter. Will keep you posted.

Are you using vacuum modulated shifts?

I'm curious as to how that'd work.
I know the old 6.9 that had a C6 behind it had a vacuum valve on the FIPL shaft...

The 700r4 is controlled by a single throttle valve cable. This TV cable controls both shift point and shift firmness. The only input the TV needs is throttle linkage and GM is very specific on how to set up this relation.
Here's the bracket I built for for the TV cable control via throttle cable.

Here's a jig I made to get the geometry right.

I so want a 4l60 for my om606 with a b&m ratchet shifter!! its so nice slamming those gears in!
i am currently beefing my chevy pickup th700 up to hold 500 hp. ratter cheap kits from monster transmissions. they also have a 1000hp kit!
RE: Adapter plate for 700R4 - Simpler=Better - 11-05-2014
The pattern is in the engine sticky, you'd just have to redrill a flex plate and double check your spacing. Starter provisions would be needed too.
RE: Adapter plate for 700R4 - Duncansport - 11-05-2014
Not to be the negative nancy here.. but if your going to go though all that $$ why not just use a 722.6. Proven lots of power handling and cheap to buy as well.
RE: Adapter plate for 700R4 - raysorenson - 11-05-2014
The chevy setups offer more transfer case options and are easier for LH front drivehsaft orientations. The merc transfer cases have RH front driveshafts, incompatible with many popular 4x4 applications. Other than that, the chevy transmissions don't have much if anything to offer over a 722.6- besides a bitchin B&M shifter option :-)

Sure i get the 4WD option for sure, just not so much for the performance car..
RE: Adapter plate for 700R4 - TurboTim - 11-06-2014
What would I use to control that transmission? I have a 2001 S500 I am parting out right now. Does that have the right transmission? I just figure 700r4's are $150' rebuilds about the same, and shift kits the same. If you could tell me how to control these transmissions I would go that route but the Trans uses a shift sequence so whatever controls it has to have a gear calculator built in.

There are a few options to use the .6 with standalone controller, a member makes a controller here on the form. And your 2001 s500 trans will only work if you change the bell housing. Or get a trans from a M111, M104 OM606 or early sprinter, there out there for under $300.
RE: Adapter plate for 700R4 - raysorenson - 11-06-2014
The 722.6 is also known as a NAG1 in Chrysler products. It's found in Porsches and Jag's too if you want to search for upgrade info.
There is a standalone called "powertrain cotrol solutions (pcs)" controller. The only pricing info I've found is in the $900 range. Olefejer on this board makes one that makes the PCS box obsolete
http://www.superturbodiesel.com/std/Thread-Gearbox-Controller-722-6-ver-2 I think he has since upgraded it with CAN capabilities for vnt control.
