We got Turners show truck fixed up with a
Super-Stock 68RFE

Mr. Hafner got fixed up with one of our billet valve bodies after throwing a code for a psi switch

most shops throw a solenoid pack in it only to discover the code comes back, and by that time the damage is already done and the customer now needs a new transmission, reason being? One clutch is on and acting like a brake pad fighting another clutch pack essentially, That psi switch code it’s throwing is bc fluid is entering a circut it should not be in, typically it’s a worn out SSV valve allowing fluid to blow by the valve lands and enter into another clutch circut, but we see it a good bit when guys are towing their campers or heavy loads, when these cummins grunt down low they produce some torque, and all that torque has to go through the transmission, the factory valve body channel plate is weak casting, so it flexes a lot! The vb has numerous other flaws as well that we correct as well, but we swap that cheap casting out with a one inch thick billet piece, flat sand the other half of vb to ensure it’s perfectly flat and straight for optimal seal
