Ihave a 98 pontiac bonneville. I am at my wits end. My husband took it today to the 7th person to look at. I am desperate. I am so sick of getting charged and getting nothing accomplished. My car started vibrating when going over 65 mph. I just assumed because we live on a rough road that it was the tires out of balance. This is exactly what it feels like. Got them balanced 3 different times to no avail. I bought new tires. Was told they were slightly out of round. Bought new tires again. Did no good. I was told maybe it was a bent wheel. I got new wheels. One mechancic that said the wheel was bent charged me 50.00 to put the front wheel in the back and say it was the wheel. I was told it could be the Torque converter. I paid to flush out the transmisson. Still no help. I have been told it was - or could be- harmonic balancer, cv axle, wheel bearing, struts, wheel, etc. I have also been told it was not these things . Each mechanic says something new. I cannot keep putting money in this car and not getting anywhere. I now have in it almost what I paid for it. Mechanically,its been a great car. It has 90000 miles on it. It does not vibrate noticeably until over 65mph or when going downhill. It does this whether you break or not. Breaking does make it worse, though. Took it today to the pontiac dealership (not the place I bought it from) They said it was the transmision needed rebuilt and said trans, and motor mount is broken. What I cant figure out is, it does this, even if you drop it in neutral. It does not matter if you accelerate or not, or even if its in gear. I already had a trans man tell me the trans was fine. What should I do? I am thinking about just having them do the mounts first, and then the trans if that doesnt work. It does not make sense to me that its the trans .if it does this in neutral. I have been screwed so much at this point I dont know what to do. They are a reputable dealership, serv. dept, but are they just trying to make more money off me.? What could be causing my shaking under these circumstance? Any help will be appreciated. I am at my wits end and I feel like it would be a mistake to keep throwing money in it. However, I could not and would not sell it like this until it was fixed anyway. They car is in exc shape otherwise, but it is a 98 model with over 90000 miles. I have been to so many mech. trying to screw me and noone really seems to know. Is it possible that it is the transm. and motor MOUNTS ? Should I see if that fixes it before I pay for the trans work? Would this make a car shake over 65mph? I no longer know a mechanic I trust. I know there are some good ones out there, but I cant find them. Even the best will gurantee the work they do, but wont guarantee that the thing they fix will be the problem. They all contradict each other. I cant keep putting every penny I have and not even fix the problem .Please help. I having serious stress over this.

Please don't post one problem in more than one forum.

How do you click on Toyota when you mean to click on Pontiac, then confuse Camry/Vista with Bonneville?

This was also posted in the Pontiac forum.

Sorry, My mistake. First time poster. I realized it was in the wrong forum afterward. Sorry to cause any problems for anyone. I am just new to this whole thing. I would not have posted it intentionally in the Toyota forum, as I was hoping I would hear from someone who has already had this problem with a Bonneville. Sorry for the inconvenience everyone.

No big deal :)
