WOW! Must have if you have a 10L1000 GM 10 speed transmission. Shifts confident and transmission running 10-14 degrees cooler on first drive…that alone tells you that changing over to NEXTGEN valve body is a good move in making your GM truck reliable again! Nicely Done NEXTGEN!

Just WOW! An absolute must do modification. GM doesnt want to fix our trucks but NextGen Drivetrain does and this valve body will fix it! Well Done NextGen!
