Automatic Transmission Problems of Buick Rainier

We have had numerous electrical and mechanical problems. The fan motor contol module when out,then the module that controls the fuel indicator and display went bad. Now less than 6 mos later the transmisson has gone bad. It is only working in 2 & 3 . No overdrive or first. This last problem suddenly started on 7/17/11. Our mechanic came and checked it out (he did not want us to drive it) and said the transmission was only working in second and third and we should not drive it and needs to be replaced or repaired. We are still paying for this car and for the last repairs on this car. I have seen several complants and service bullitens on this problem and the problem with the gas gauge. Has there been any recalls or acknowledgement of these problems by gm?.

Possible fire hazard and accident due to oil cooler line corroding out. Normal driving. Repair and replacement of oil lines. This was only by shear luck that this was not a serious accident or fire with injuries or death.

I have a 2004 Buick Rainier that had the transmission rebuilt with 28,000 miles and again at 64,000 miles.

At 46,403 miles I noticed that the engine would rev up more than normal when shifting gears. Took into the Buick dealer and upon inspection the tech found that there was scoring in the valve body of the transmission. Extended warranty took care of the issue however I was told that this was rare for raniers.

Transmission leaking, shifting hard, revving high during shifting, and 'hunting' for gears while traveling.
