This Astravan came to us for a gearbox overhaul and ecu remap and rolling road set up.
We remove the gearbox, and have it fully stripped down and all the internal components are cleaned and inspected. This also allows the transmission cases to be fully clean as well, something often overlooked if bearings are replaced with a gearbox in situ. The gearbox internals are then reassembled and refitted with new bearings throughout.
Once finished the van was on our dyno for full mapping and rolling road set up.
