Hi, i have a 3394 with 24 speed trans that i have rebuilt the trans(all the clutches). got the tractor back together and when running i get the trans light on. i have done test as per repair manual. when dead heading and plugging off signal line ports to the piston pump i get the correct pressures(330 psi). when i hook up lines to the flow divider(hook lines up correctly) i am only getting 80 psi at idle and 150 psi at 2100 rpms. i tried to shim the pressure regulator in flow divider, pressure did not change. i tried running the power shift thru the 6 power shifts, the pressure does not change. not sure if pump is weak or if there is something else to check.
