As usual I'm going to torment myself and try to straighten it out myself. I have learned through Transonline.com that the modulator pressure is supposed to be set at 58 psi for this unit. My immediate problem is finding a fitting to adapt my pressuse guage to the tranny. The plug measures 8mm. Everywhere I go asking for metric fitting, they look at me and say " They make those?" Anyone know of a good source for metric fittings to adapt to 1/8" npt?
