I am convinced one of the best features of my 116.120 is the 722.120 transmission. I built the unit myself and went to the trouble to order all the selective plates for the clutch packs and adjustment struts for the bands.

This did take some time to get all the parts together, but it made for a much better functioning transmission.

I also use Type 'F' Fluid in these units because it has a higher frictional coefficient which gives a more solid shift. We used it at the dealership exclusively up until the time I left in 1992.

My 1978 300 SD used to take off in low gear all the time. However, when I rebuilt the transmission, I used a 1979 valve body, which now shifts differently altogether.

At idle against the service brake, the transmission is now in second gear. This minimizes 'pull' in gear and gives a smoother feel to the idle.

As soon as the car starts rolling, the transmission shifts to 'low' and gives great acceleration. After several adjustments to the vacuum modulator, the shifts are immediate and very solid. There is no indication the trans is about to shift, it happens very quick.

I had always favored the '6 bolt' variant of the 722, but after rebuilding my 722.120, I must say I am impressed at the rugged construction, especially the planetary units.

Just thought I would say something nice about the 722.120...Bert
