1999 Pontiac montanna minivan. The transmission repeatedly slams / hammers into gear. Resolution is to stop van and restart vehicle, most times this stops it untill it starts acting up again. This can happen 7 times in a 50 mile trip or only once. This is dangerous to have to stop in heavy traffic to do this. The power door is also a problem. Will not shut properly, have to close 3 times before it will finally close.

Intermittently transmission will shift very rough and hard, and transmission emits a whining noise. Once it starts, it continues until the vehicle is turned off and resets. It appears to be happening when the temperature of the vehicle increases to about 210, but it's not consistent. Also had intake manifold gaskets replaces for $700.

Van shifts hard and often makes a loud "clunking" noise. Dealer recommends ~ $1100 in repairs to the transmission, several non-dealer repair shops recommend rebuilding the transmission for ~ $1400. Problem started several months ago and now seems relatively severe with the service engine soon light now on consistantly. Problem seems to go away if the van is shut off for a small length of time. Another transmission problem and yet no recall. Red

Transmission quit running while driving on interstate with no warning.

- South Berwick, ME, USA

I had three transmissions, a cracked head because of over heating, water pump and heat sensor, oil in one cylinder, a short in the rear lights with dealer saying I (should replace the lighting structure on both sides) $200. ABS system sensor front right side wire burned through $500. The $200 and $500 I have not done yet, should I wait until it's an even $1000 more to spend more money? there are more problems.

I have a '99 Pontiac Montana with GM's infamous V6 3.4L engine. Just had the intake manifold gasket job at 56.5K miles. This is a noted problem, with sudden over heating and the car stopped on my wife. Also the vehicle is on its third tranmission.

Complete transmission failure replacement cost $2600. This was caused by an internal radiator failure, which transmission fluid into the engine coolant, destroying engine gaskets and requiring $1700 in engine repairs. That's $4300 in one month, on a four year old vehicle. Note the number of transmission problems reported on this vehicle. Why no recall?

We have occasionally had problems with the transmission shifting hard, whining & banging into gear-this goes away if you turn the vehicle off & then back on. It occurrs at slower speeds not highway speeds & seems to happen only on short trips or longer trips with several stops. Recently there was a coolant leak in the system, which a local shop "repaired" for $67 the first week of October. Almost two weeks later the vehicle began running hot again & we were then told it needed a new head gasket. We had the vehicle back for a week when after getting off the highway & stopping for a red light the vehicle started to stall & the low oil pressure light came on. After parking the car & restarting it -it started making a horrible sound & we had it towed in to the nearest Pontiac dealer. There we were told that the head gasket shouldnt have needed to be replaced that those engines almost never leak from the head gasket but apparantly they commonly leak from the intake valves. In addition, they said that the garage that did the head gasket did something wrong which caused a blockage in the engine & prevented oil from getting into the top of the engine. They said there were two bolts that were loose & eventually found to be sheared off & that one of the outer heades-not the cylinder heads - were cracked. I have no way of finding out what actually caused the engine failure. I found no technical service bulletins on the head gaskets or the intake valves. Rif the engine had to heads a ardiastiotnetrstarting ccor.

Purchaused used (6 months old) have now owned auto for 2 years. At 38000 miles transmission starting shifting harsh at times, had to replace transmission. Engine has started acting as if it is going to stall for no apparent reason. Radio has been replaced 3-4 time, due to garbbled display. Most recently however, I had door locks repaired, and was told that the wires to the locks were damaged due to the water intrusion caused by the air conditioning leak into the auto instead of outside the auto.

- Jerome, MI, USA

Vehicle has been in dealer's repair shop over 6 times for transmission. Dealer replaced transmission, and vehicle jumps and jerks.

- Emporia, VA, USA

Vehicle will drift backward when stopped on hill in drive gear(forward)and without brake being depressed. Same situation will happen when in reverse gear pointing downhill when brake is let off (the vehicle will coast in forward direction). I feel the transmission should catch and prevent this motion. All other automatics that I have driven have not exhibitted this problem.

- Allison Park, PA, USA
