| Cannot get air throught vents in dash, all controls work properly vacuum actuator moves, there is vacuum at the swithc, no one knows the answer paint on gas door bubbling and looks like it is going to fall off transmission shifted hard into 2nd gear since we bought it ( 54000kms) finally started to slip , bought used trans and had it installed, quoted 3000.00 to rebuild, dealer was past even belief. abs comes on when coming to a stop every time . lf front sensor reads o mph when other sensors read movement causing it to assume a skid situation, replaced sensor at 205.00 no better, does not set code in computer according to mechanic. pulled fuse. has had vibration in driveline since purchased no one can find anything sugeestion range from replace all u joints, did some of them no better to replace rear end. it is not possible in nova scotia to obtain a blasting permit to blow up your car even if you take precautions and hire a professional. i have never in 40 years of driving some bad stuff from old english cars to transport trucks with more miles than there are numbers, ever had this kind of problem, most things can be fixed. you have never lived until you have taken the whole dash apart on one of these, the vehicle was designed by madmen. | |||

| The chevrolet astro shifts gears violently. the problem was first noticed as i left an intersection and the van violently shifted gears throwing my family's and my head back with extreme force. thinking that i had been rear-ended and knowing that other cars were in front and alongside my vehicle, i quickly stepped on the brake, almost causing a true rear-end collision. the vehicle was not in warranty so i took it in for inspection by my local mechanic, who had previously worked as a service tech for a chevy dealership. he was unable to find the problem. he contacted one of his friends who still worked at the chevy dealership where he was formerly employed. my mechanic told me that his friend stated that the defect was known by chevrolet but there wasn't any recall and there was nothing they would do about it. i paid a hefty price for what was supposed to be a great van only to find out that chevrolet has manufactured a vehicle knowing that it has severe defects in the transmission that could cause costly repairs, injury, or possible crash-related deaths and refuse to remedy the situation. how many more people must continue to drive an unsafe vehicle beforecorrective action is taken?*ak | |||

| Repeated attempts to fix transmission beginning with a complete rebuild at a certified facility; transmission may function properly for as long as 2 months. repeated visits to the transmission shop are met with apologies, and stories of the same design transmission with the same problems from other individuals. i at first suspected the mechanics, but research has shown there are many other astro van owners experiencing the same problem; believe it to be a manufacturing defect. *ak | |||
