Factory arms & trapezoid mounts. I'm also using a factory CV-type trans output flange which should be an available item common to any 722.6 G, i.e. G500. I do not have this in my hands yet... will report back once confirmed. Obviously, this requires the use of a CV-type short-shaft & CV transfer case input flange also.

Or you could use a sprinter 4 bolt output flange and adapt the end of a sprinter d-shaft to your existing short shaft, like Mr. sprinter 711651 did here on his 6 speed conversion: http://www.clubgwagen.com/forum/viewtopic.php?f=27&t=2913&hilit=6+speed+transmission+flange

Or fabricate one flange like Axle B. did in the UK: http://www.clubgwagen.com/forum/viewtopic.php?f=18&t=4784&hilit=flange&start=20

There are 2 flavors of MBZ drive flanges, the early type (roughly 1953-1996) and the late type (~1996-present, exclusive use of the 722.6 marks the change).

The early 'smaller' flanges came in several d-shaft bolt patterns depending on application (3 bolt for passenger cars, 6 bolt for van/early G, and 8 bolt for later G) but they all share the same output shaft dimensions of 29mm diameter with 27 splines. All 6 of the output/input shafts on a 460 are 29mm diameter with 27 splines.

The later 'larger' drive flanges also come in different bolt patterns (3 bolt for passenger cars, 4 bolt for sprinter vans, and the homokinetic flange for the G. *I think there is a 6 or 8 bolt G flange that fits a 722.6, see FSM image here: http://www.neoriginal.ru/cat/mb/part__1_44W_FG_202033_23Y_GA_722631/27_095) Im not 100% but I believe the larger flanges use a 34.6mm diameter 26 spline (same as G axle shafts), can you confirm Vadim? This is the flange used on all modern MBZ transmissions (5spd auto, 7spd auto, and various 6 spd manuals).

MBZ still uses the 'smaller' flavor of flange for t-cases and differentials.

Chris,

I think the 722.6 output shaft is 32mm but will check tonight. I have some CVs to compare the splines to as well.

Great info. about the flanges!

Has anyone tried using a speed gems transmission adapter for a GM 4L60E automatic?

Hoping to resurrect this old thread. Wondering if anyone completed this install as I am quickly heading this direction.

I don't believe there is an 8-bolt flange for the 722.6 spline diameter. It would be a custom part. I may prototype some with 4130 steel this summer.

I'll take 2 V!
Plus a few custom 722.6 bell housings that allow that trans to bolt up to M110/OM617 please if you don't mind...
