Can you bolt an OEM A518 O/D unit to a 727 transmission?
Some idiot huh.

Makes since to me
As 93' said, the trans would be the A518. It's a 727 3 speed trans with a o/d bolt to the tail end to effectively make it a 4 speed. The transmission doesn't have a locking torque converter, and the stock torque converter tends to be rather loose. In terms of durability though it's a pretty stout transmission that will serve you along time with proper maintenance and common sense operation. I believe fluid changes are recommended around every 25k and the band adjustment at the same interval. Though, because of the limited amount of material on transmission bands, I usually won't adjust them until I start to have a shifting issue.

That also is understood. I don't the full mechanics of either trans, but one is 3 speed, another is built to marry an overdrive unit. The 518 is going to have the hydraulic port, valves, plug holes, and even an appropriate mounting area for the od unit. All makes good since.

Crow, anyone?
A-518, 46RH, 46RE - This series of transmissions (hereafter called A-518), is based on the Chrysler A-727 series transmission design. Gear ratios are the same as A-727-series transmissions. They share many of the same internal parts with A-727 series transmissions except for the OD tailshafts. The transmission pan has an identical shape to the A-727 series transmission pans, but it is much deeper. The OD units will not interchange with tailshafts from A-727 series transmissions.
Not really sure who's eatin the crow here.?.? 92 has been just as right on as all the rest of these cats.

The only point I contested was about the 518 OD unit bolting up to a 727. That's it. I knew from experience that it could not be done. I was trying to be helpful with my experience so other people over there wouldn't try to buy an OEM OD unit to add to their 727.

We thought about this long and hard for our 440 swap in the ramcharger. It was easier to machine off the bell housing, and get an ultra bell to bolt on the 518 so it would bolt to a big block. We eventually scrapped the idea and went with a gear venders OD.
