We are MaxxECU dealers and one of the great features of these ECUs is that they support the 8HP45, 8HP70 and 8HP90 gearboxes. To unlock the all the features of this combo the transmission ECU / TCU needs to be reflashed.
We offer a reflashing service – there are a few options:
Bring the gearbox to us and we can reflash it while you wait
Send the gearbox TCU to us and we can reflash it and post it back
Rent the tool from us (coming soon – let us know if you’re interested in this option)
All these options are available to arrange from our shop: 8HP45 8HP70 8HP90 MaxxECU firmware flash
