Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

2000 Pontiac Montana Owner Comments

problem #3

Feb 282011

Montana N/A 6 cyl

  • Automatic transmission
  • 172,000 miles


I have had this problem twice my 2000 Pontiac Montana (extended wheel base) over the years. It currently has 173k miles on it but I've been taking very good care of it so it could still work for another 100k if I had my way. The first problem is that 4 years ago, I had to have the transmission rebuilt when it began to try to shift back and forth between gears at certain speeds and especially when I was traveling uphill. Everything was find for the next 80,000 miles and then it started doing the same thing. I've just had it rebuilt a second time! The fluids were always kept full and my careful driving style is not hard on the car. So is this a case of a poorly designed transmission by GM? Do I have to move away from American made cars?

Montana Extended

  • Automatic transmission
  • 60,000 miles

I had the problem 2 times with the transmission, now it slips, had the motor gasket problem. 2 times i had to change the relay for the fan (was only working on high( 4 and 5)). All lights are going high and low in the first 15 minutes. Painting problem too. The lock button is not working on passenger side. There is some water that is getting in the car when it rains. That's enough, that's why American cars company is loosing the market war against others.

problem #1

(reported on)

Montana 3.2L V6

  • Automatic transmission
  • 88,000 miles

Complete transmission failure at 88,000. Very known issue as reported by transmission people. I had this happened 2000 GMC Jimmy and the 2000 Montana; same model transmission. Known part failure that is responsible for keeping pressure constant in transmission. The problem happens in hot weather conditions and faulty part allows the transmission pressure to go down; hence damage. GM knows about poor design; does nothing.
