Auto trans, steep incline roll back

[immortality]

Hey guys,

As the title says, In the missus Calais (VX, L67, 4L60e) when on a steep incline the car will roll backwards (idling, transmission in Drive) from a stand still.

Transmission behaves in every other respect. Really not sure what the cause would be. Plenty of transmission fluid, not burnt etc

Any advice or suggestions welcome.

Thanks

sounds normal thats why the road rules say use the handbrake at every intersection LOL

Yeah I agree it's pretty normal if steep enough, you can bump the base idle up in the engine & it will fix it but then will use more fuel, brakes & try & pull on the flat stopping!

Bugger,

The idle is already higher and I wanted to knock it down a bit

My old VS V6 didn't seem to ever roll back and it had a lower idle if I remember correctly. Maybe it's the slightly looser converter used with the L67's?

Might have to play with the open loop idle to try and save some fuel doing the stop/start tango around town.

Just need to define the stuff in the XDF.

if its a larger converter it will definitely have less drive effect at idle!
