I got an huge bang and jerk when starting off from a stand still. The 2007 Chevrolet Express 3500 with 6 litre engine, only had just 30,112 km on it when this first started to happen. It has not been heavily used. No towing or heavy loads. It currently has 34088 km on the truck and now does the bang and jerk almost every time you start from a stand still. Right after that first time a red check engine light on dashboard came on. I bought an innova 3030 to check the error code. The error code was p0894 - I did a search on a site and found a NHTSA: action number: 10021019 service bulletin number: 222381 for this condition - slip condition in 2nd, 3rd, or 4th.
