I have looked all over and in all my manuals here and cannot find the oil "pressure" parameters for my ZF-BW-190 Tranny's.. I am running VDO guages that read up to 350 psi. The last Captain and owner went to Sigma-Netic's 774.22-S01R-285D 2 wire sensor that reads upper and lower pressures. etc. Apparently works.. On the stdb engine they recently replace the sensor w/ a newfangled 4 wire sensor with dial up parameters.. (not connected yet.). Well the original sensors... (alarms) are 2 wire.... I prefer to go back with the original 2 wire pressure senders... But do not know which ones they are supposed to be.... Should I just say screw it and go with the 4 wire dumbed down to 2 wire or can someone give me a VDO part number or the correct pressure parameters for these transmissions??
