In my case, the jolt after a slow rolling stop can be really bad. The engine will briefly speed up as I step on the gas while still barely moving and then will engage with a real kick. For a moment it seems the engine and transmission aren't connected. It also seems that if I come to a dead stop there is no problem. It's the worst when I pull into my driveway which is on an incline and let off the gas for a second. When the car stops moving or maybe starts to roll back a bit and I step on the gas there is a really big kick as the engine speeds up for a half second and then engages. I took it to a transmission shop and unbelievably the jolt was gone during the test drive and there were no transmission or engine codes. So after reading many very interesting and informative posts on this problem and many suggestions on the possible causes I just have one question. Has anyone out there done something that has truly fixed the problem? If so I'd like to hear it.
