Engine: 3.0 V6
Transmission ECU Type: GS8.20
Original Software: Unknown, likely V5 given age
New software: V9
Car : 1998 3.0 MV6 Estate (wrongly running an AR25 instead of AR35 at the time)
Updated by : Local dealer (Dickens) for £35, other local dealers wanted much more, or refused to do it due to lack of knowledge.
Gearbox was updated after reading about it on here.
Immediate difference was noticeable, the car felt smoother and more powerful, seemed to get to speed a little quicker.
The 50-60 MPH jumping gear in the lanes was much reduced, the box seems to hold gears more appropriately with less changing.
Ljay had a 2.2 Omega at this time, and debated the point in an update, until she drove the updated map, then wanted it on hers too.
Unfortuantely that one had an unusual ECU which didnt have an update available.
Other Points.
An ATF (Fuchs Titan 4000) and filter change was performed sometime later, which improved smoothness some more.
Gearbox eventually became unreliable, dropping to manual mode frequently, it was swapped and found to be incorrect for the car, the correct AR35 was then fitted, with a new thrust washer and ATF. The car was smoother than ever at this point.
This was written from memory of events happening 2-3 years ago.
