Buick Lacrosse

[march00]

I have owned this car for 6 months, sometimes when I go from reverse to drive there is a thump which to me means that the transmission is not reacting fast enough. Dealer says its nothing...
Also, what is that yellow light with the explanation point in the middle of it?

thanks
Nick

IF the light is round with an exclamation point, it is a brake issue. It is the same light that will come on if you put the parking brake on. If it looks like a U with an exclamation point inside, then it is your tire pressure monitor. One or more of your tires is low. That is what is in my wife's Lacrosse manual. She has no transmissions issues.
My Lucerne, on the other hand, has the same problem with the transmission. Dealer says is it nothing also, but as far as I am concerned it is not normal. Wrote to GM and they finally extended my drive train warranty. I figure the minute the extended warranty is up, the tranny will fall out on the Interstate.
