I just thought I would mention that I added a little technical manual for the Pennsylvania Panzers and Meteors to the Manuals / Tractors / Pennsylvania Panzer section of the site.
The reason I'm mentioning it here is because there's something in it that will apply to multiple brands. The Meteors used a Sundstrand hydrostatic transmission (called Pennamatic Drive ) and this tech document has a really nice hydraulic diagram and written description of how the unit works. It's called "T-75 / 1107-1110 / 1010-1012 technical manual"
