I have the same performance coming from my 99' venture. Is that the tranny? I'm a Soldier and I have carpentry skills but I know nothing about cars other than basic stuff. BTW, I don't have codes showing up yet. Let us know how it works out for you. GL

I have a 99 Montana that had the same problem. Kicks like a mule and a code comes up. It is the torque converter clutch lockup solenoid in which you have to rebuild the transmission to fix it. I had it checked at a dealership just to be sure. You have to take off the side cover and to do that you have remove the transmission. They said it cannot be accessed by the bottom cover. They said they could fix it for $1295. I said no thanks. I drove it like that for years until I had to replace the motor due to the intake gasket problem that it is famous for. When I replaced the motor, I also replaced the transmission with a GM remanufactured one from a dealership in my area for $1600 and put it in with the motor. This one works great. No more kicking and it shifts smooth and doesn't shudder on take off. I guess its up to you on what you want to do. Good luck.

I had a 2000 Venture with the P1811. It had harsh shifts after it warmed up. I was going to replace the pressure control solenoid, but decided to try solution-in-a-bottle first. I used Seafoam TransTune and IT WORKED! Ten miles after pouring in the Seafoam I changed the fluid and the problem went away. Woo hoo!!

I'm happy for you. Hopefully that works. Mine didn't do it so much when it was cold outside, but when the hot summer hits and it would get hot, it would do it every time. I've changed the fluid and the filter with no resolution. I figured I would just live with it until it went out. If it went out, buying a new one and having it replaced would be the same cost as fixing the old one. Thats pretty much a no-brainer. Drive it like you stole it! Good luck.
