    My first trans rebuild is a 4L60E in a 96 Silverado K1500. Installed the trans and it works right until the temp gets up, then in overdrive trans oil blows out. Fluid was coming out the front seal until I replaced the front pump bushing and seal, now not quite sure where. Was wondering if perhaps I ground too much flat in the press relief valve in the pump. Already replaced press solonoid, press switch and spacer plate. Tired of throwing money at it and need help.
