Tranny:If the pressure is too hi it will wipe out the pump and converter neck. You need a 300psi gauge and tap into the mainline port.Should be aprox 115psi at idle and rise to just over 200psi when brakestanding in D. over 280psi when brakestanding in R. This is a quick full throtle blast. Pressure must rise smoothly with throtle.Main problems with these units is the force motor sticking also called the EPC solenoid. Controlls line pressure w/voltage decrease. This solenoid is in the trans and there is an aftermarket one available for half of new (aprox $280.00) this is adjustable alsoso you can crank it up for firmer shifts if need be. Also these have proven more reliable (non clogging pintle type)Call if you need one. Jeff 503-885-8852.

I replaced the tranny awhile ago, and now I am experiencing a bang sometimes when shift from 3rd gear to 4th gear. Sometimes it works fine. But sometimes the car might even shake while it is shifting? Is it a big problem? I brought it back and the mechanic said the pressure is too high and said is not a big deal. Can somebody help? Does anyone knows if the transmission have adjustment that you can do like the mercedes? Thanks!
