Core surcharge is sometimes charged as we require the old unit back to either re-manufacture the part again or this may be due to a request of our supplier.
Please remember without returned core we are unable to rebuild and supply again!!!!
Core charges are dependent of the unit supplied
Typically a £80.00 charge could be applied to a genuine ZF torque converter as a £750 surcharge could be charged to a ZF6HP26 remanufactured transmission.
