Project Carbon™ AS68RC High Pressure DIY Valve Body Upgrade Kit - V4.0

Next Gen Drivetrain, Inc.


     The AS68RC is riddled with highly expensive problems that largely derive from a couple of leaky valves and a set of utterly useless accumulator pistons. This dinosaur of a transmission can be traced back to the Toyota Land Cruiser of the mid 80's and was never designed to accommodate the arduous demands of the diesel crowd.

     As always, Next Gen Drivetrain™ best-selling drop-in Project Carbon™ DIY Valve Body Upgrade Kit are the driving force in providing efficient and inclusive solutions to these evolving transmissions. This kit addresses both the leaky valves and the accumulation leaks with this kit, even going so far as to include drop-in sleeves to replenish the B1 and B2 valve bore with NO machining needed! This kit can also be configured with a high pressure spring that increases line pressure in all forward gears by up to 25%, NO tuning required!
