Benjamin
On the spec sheets that I have for the 643 and 653 they show max torque input as 640 ft/lbs. Ratio's are the same. I donot have any info on the 647

Joe,
Perhaps I can help you a bit on the MT-647. It is similar to the MT-644 except it is electronically controlled.
The MT-644 and MT-654CR specs are:

Ratios (MT-654CR): 4.17:1, 2.21:1, 1.66:1, 1.27:1, 1.00:1, -10.76:1
Max input power: 300
Max input torque (MT-644): 780 lb/ft
Max input torque (MT-654CR): 950 lb/ft
Input speed (MT-644): 2,000-3,000 rpm
Input speed (MT-654CR): 1,800-3,000 rpm
Torque converter ratios (MT-644): 1.92:1 (TC-494), 2.21:1 (TC-495)
Torque converter ratios (MT-654CR): 2.21:1 (TC-495), 2.70:1 (TC-497)
