From February 13, 2015, ZF began to pay for the recovery of the old valve body! The recycling process is as follows: The first step is to carefully disassemble the new valve package to avoid damage to the original package. The second step is to replace the transmission valve body and leave the replaced old valve body for 5-10 minutes to remove residual oil. The third step is to pack the old valve body with the original red bag or anti-static bag. The fourth step is to fill in the "Zef old recycling information card" and put it into the original carton together with the old valve body. In the fifth step, the packaged old parts are handed over to the distributor who sells the valve body. Upon inspection, the new part can be deducted for the purchase cost.
