H3 Cold weather starts. <30°

Has anyone ever experienced the H3 "lurching" forward when starting in cold weather? Had the issue this morning, temp was 19°. Truck lurched forward like it was in gear when first started. Never had it happen before!

TIA

Never had that happen. Automatic? How many miles?

My H2 does that. What I found is it is from the fluid that is left in the torque converter. The effect is more pronounced in the cold when the fluid is thicker.

My 2010 Alpha/Offroad does it sometimes when it cold. There is a TSB on it. They call it movement on startup after cold soak.
