1999 Chevrolet Venture Transmission and drivetrain Problems

“Began noticing harsh shifts in automatic transmission of 1999 Chevrolet Venture van in summer of 2003 when van had approximately 85,000 miles. In fall of 2003, harshness of shifting became more pronounced and van was inspected by a transmission repair faciilty. I was advised that my transmission was failing because of insufficient fluid pressure, and if left unaddressed, the transmission would soon fail, leaving me stranded at the location of transmission failure. …”

“I have had 3 main problems transmission, headlight moisture and airbag light illumination my 99 Venture has 79k miles on it and that transmission is shifting hard (dealer suggest a drain and flush) at 60k I had a valve in the transmission replaced for 800 dollars. I am afraid we will be replacing a transmission at 85000 miles. I can not believe it. The air bag light has been coming on since we bought the vehicle. We have had it in 7-9 times fixes ranged from clearing the code to tightening up a plug. The head light units have been taking on water and burning out lights for the last 20k miles. …”

“My 1999 Chevrolet Venture minivan has had numerous problems. The one I am most concerned with is the automatic transmission. The transmission makes the car jerk when I either slow down or stop in heavy traffic. This happens when I press on the accelerator to gain speed again. It doesn't happen every time but more often than not. There are also times when driving down the road it whines. Also have a problem with what I figure is electrical. Sometimes the ABS light stays on and then eventually goes off. Also, the air bag light comes on intermittently.”

“Venture with 89,800 miles has been hard, harsh shifting for some time, also whines. Dealer said possible pressure control solenoid epc needs replaced, no estimate. Dealer suggested to run vehicle until it becomes a real problem. Also discussed with tranny shop, they experienced many of these tranny problems, usually code 1811, replace pressure control solenoid (epc) but to correct problem tranny needs to be rebuilt, estimate $1,600 to $1,900 to do.”

“Vehicle will shift hard when driving in city (stop & go) conditions,to the point where you can feel the jolt in the floorboard when shift was made (actualy broke traction a couple of times) this vehicle has not been (dogged) or raced at these times of acurrance.once vehicle has been on the highway for a couple of miles (on the way to dealership) for service tech. To ride with to diagnose problem shifting is smooth again.”
