1356 Electric Shift Emergency Shifting; "... Yes, pt #84 is the shift shaft from the motor for the electric t-case. What i did was convert a pick-up/ F-350 series, slip yoke rear output, manual-shift 13-56 to a fixed yoke rear output, manual shift t-case by swapping the rear case half, tailhousing, yoke and output shaft from an electric-shift 13-56. Blade has confirmed this in previous posts as well that the internals are NOT the same for the manual and electric shift versions of the Borg-Warner 13-56 transfer case. The housing is essentially the same and interchangeable, except for the hole for the shift motor on the electric version. The 3/4" round hole that I plugged was where the motor mounted and the shift-selector shaft would be inside. The connections to the shift fork are what's different on the two versions. I suppose if you could physically turn the shift shaft manually, without having the motor installed, you could shift from one range to another. I think this would be rather hard due to lack of leverage. I know it's quite hard to shift the manual case without the in-cab lever and linkage attached..."
