#16 of 498 2001 Pontiac Grand Prix Problem after problem!
May 01, 2006 (12:17 pm)
Hello whoever can help! First of all my catalytic converter went out...luckily this was under warranty and I got it replaced free. About a week later, my transmission went out. Had it replaced leaving my car in the shop for 3 months. The mechanic said the pan underneath was full of metal from the transmission. Well, now my car has started making this noise when I'm driving...it sounds to me like an airplane fying through the air. All I need are some wings and I feel like it would take off. My boyfriend thought is was the tires so he rotated them...still making the noise, but seems to be getting louder. I'm also having some trouble with my power steering and the trac off light stays on most of the time and the car makes a roaring noise quite often and I can feel it when I depress the brake pedal. The mechanic that replaced the tranny said it would be ok to leave it as is because it's not actually affecting my brakes. (I couldn't afford to fix it at the time...tranny was almost $2,000)I only have a little over 80,000 miles on my car. Does anyone have a clue?

It's me again! Just thought ya'll might need a little more info about my car. It's a GT with a 3800 series engine. I would also like to add that the car sounds pretty good when it's just idling. It doesn't start making the airplane noise until I begin driving. The faster I get, the louder it gets! The service engine soon light comes on but doesn't stay on. I just need some help. I already know that a wheel sensor needs to be replaced which I've been told that the whole hub has to be replaced at the same time...over $300. I've already spent all of my savings on the tranny! Someone please tell me that my other problems aren't serious!!

The catalytic converter is covered under the emissions warranty for up to 8 years or 80,000 miles (130,000 km). I have a 2000 S10 that had just under 80,000 miles when it went. I moved from Canada to the U.S. and GM still covered the converter replacement free of charge.
#20 of 498 Transmission Problems?

My automatic 2000 Pontiac Grand Prix has been making a whining noise and is difficult to go into gear occasionally. I took it to a shop and diagnotics shows 1. Torque Converter 2. TFF Intermitent Stuck on on and 3. Maximum Adapt Long Shift. The mechanic clered the codes and took it for a ride. Checked diagnostics again after the ride and no codes. I drove it last night and it started that whining racing noise again and then eventually shifted into gear. Is anybody familiar with this? Do I have a transmission problem, only does it once in a while.

same problem. 2000 grand prix gt auto trans. Only notice this problem when car warms up and/or extended driving. Getting the "whinning noise" and also hard downshifts in all gears. only 55k on it! Turn the car off, wait a minute, turn back on. Problem goes away. msg 119-120 sounded similar in problem. Have you had this problem fixed?

I OWNED A 200O GRAND PRIX GT AND HAD THE SAME EXACT PROBLEM. WASTED ALOT OF MONEY TRYING TO FIX THINGS THAT WEREN'T BROKEN. THE PROBLEM IS THE VALVE INSIDE THE TRANSMISSION IS CRACKED. THE ONLY WAY TO FIX IT IS BY TAKING THE TRANSMISSION APART AND REPLACING THE VALVE. FIND A TRANSMISSION SPECIALIST AND TRY TO GET IT DONE RIGHT AWAY. THAT IS THE ONLY THING WRONG WITH YOUR CAR. IT TOOK ABOUT 4 HOURS AND COST ME ABOUT $500.00. IT SHOUD NOT TAKE MORE THAN THAT TO FIX IT.

Hello thank you for your reply.... my car is totalled! Theres nothing left of the engine at all. I wish I would have known about this problem before so I could have it checked. I have contacted Pontiac so they do know I don't think it will do anything, maybe help someone else, they are supposed to get back to me in a day or 2.

I had s similar problem and thought it was the Transmission on my 1999 Grand Prix. It turned out to be the Power Steering Fluid being very low. Does your noise get worse when you turn the Steering wheel when in parked mode, Check Power steering fluid and TOP it up and see if you get the same noise. Power Steering Fluid level inidicator is hidden at the back part of the engine
compartment and not checked regularly by service mechanics.
