It's never happened to me. Did it give you any codes?

[turbotibbo]

no codes no flashing tow haul light . i do drve it kinda hard but it seams strong no slips ? i dont no mabey a sensor ?

[Evil Eye]

Sounds more like a flow issue, but it should have thrown a code. When was the last time you changed the tranny bypass filter?

i was changed 4000 km ago when i installed the gogo direct clutch solenoid the fluid is cleaN and toped up ? it just seems like an out of the blue thing to happen andd i cant explane it ?

I guess just keep an eye on it. It does sound pretty strange.
