Measure Hydraulic Pressure on a GT 14

[brenntl 0]

After reading the Sundstrand Automatic Trans Repair Manual, it is not clear where to connect a pressure gauge to measure the high pressure pump output (550 psi to 700 psi) on a '69 GT 14. The manual shows the location on '73 and later hydrostatic systems which don't look like the earlier ones. Any help is appreciated.
