Back in the early 90s my brother bought an old GT-14 somewhere in Pennsylvania and hauled it to Stinking Creek, TN. Since it needed some work done on it, I purchased a copy of Owner's Manual, Parts Manual, Hydraulic Unit Manual and Automatic Transmission Repair Manual from Toro Wheelhorse.
The Automatic Transmission Repair manual is about 65 pages and covers about everything. This is the most important of the manuals to me, and as you may expect it is the poorest quality of all the manuals. The text is readable, but the pictures and drawings are poor quality.
I have scanned in all these manuals as pdf files and am in the process of cleaning up some of the pages.
If anyone is interested in them let me know and I will see about uploading them.
