6L80/6L90 TransLab Engineered Pump Upgrade Kit
"Drop-and-Go" / No-REAM Series of Superior/TransLab QUICK SOLUTIONS
After years of testing, all the issues rebuilders wanted in a pump upgrade kit are in this kit and ready for your 6L80/6L90 automatic transmission.
PR Valve upgraded seatless design. This pump upgrade kit addresses over-pressurization which causes major 1-2-3-4 and 35R drum and piston cracking by lowering failsafe/brown-out max line to 285PSI to help prevent high pressure parts breaking! TransLab's 6L80/6L90 transmission pump upgrade kit also improves TCC apply, lube and pressure regulation stabilization.
