The dreaded P2747 Auxiliary Transmission Oil Pump Driver pro

[hybridbatterysolutions]

Hello All,

If you have this fault you have my full sympathy

The First thing to be said is despite the fault description - I have never ever found the driver unit (ECU) to be at fault ever.

When I had this problem with my GS450h I was able with the assistance of Carl911 to repair it myself & I have in the past taken the job on for a few of my customers with the proviso that if the speed sensor magnetic ring inside the pump breaks during strip down it will necessitate renewal of the whole pump at around £1100 ish plus fitting. The job itself can be quite tricky especially if you are not in the mechanical industry & I can fully appreciate anybody's reluctance to tackle it themselves, so I just wanted to let you all know that I can now offer this service generally at less than half the new unit cost with the same proviso as before. So if you are unfortunate enough to require this repair please feel free to PM me.
