Could someone post the procedure to check pressures at various points in the transmission pump system for a D6C 76A0713. My old, tattered service manual is missing the relevant pages. Thanks!
Hi I could not find your serial number but these specs are from a common d6c serial number Oil Pump For Torque Divider (Power Shift) (5M7864) Rotation is counterclockwise when seen from the drive end. For bench test use SAE 10W oil at ... 120° F(49° C) Output (minimum) ... 3.2 U.S. gpm(12.1 lit/min) With pump at ... 500 rpm At a pressure of ... 120 psi(8.4 kg/cm2) (1) Diameter of the shafts (new) ... .7407 ± .0003 in.(18.814 ± 0.007 mm) (2) Clearance between gears and cover (new parts) ... .0020 to .0035 in.(0.051 to 0.089 mm) (3) Torque for nut ... 40 ± 5 lb. ft.(5.5 ± 0.7 mkg) (4) Bore of bearings (new) ... .7425 ± .0003 in.(18.860 ± 0.007 mm) Oil Pump For Power Shift Transmission (9S9384 and 3P6816) Rotation is clockwise when seen from the drive end.

Thanks for the info but I should have been clearer in my request. I am looking for pressure specs at the various pressure taps in the transmission hydraulic control system.
here try this it will be close
You need REGO1334 for a 76A it is some what different . Bob
I tried searching on SIS for REGO1334, but it does not come up, sorry.
