#67 of 74 Torque converter and solenoid replaced but engine light come on
Dec 16, 2010 (8:34 pm)
I just got my 99 Bonneville back from the shop yesterday. I took it in after a series of issues that started with a violent jerking after low speed coasting and stepping back on the throttle. It did this twice in a row, so I dropped it off at a local shop and they didn't come up with any fault codes. I drove it on home and used the car for another month, but noticed a few peculiar shifts especially after coasting out of a corner and stepping back on the gas.
Monday I went to town in it and the Check Engine light came on, and it started shifting hard and a couple of time it just didn't seem to want to go after shifting. I dropped it back off at the shop and this time they informed me it was a torque converter and solenoid fault code which made since to me because of the way it was acting. They replaced these parts.
I got the car back yesterday and all seemed well for the first 12 miles and the Check Engine light came back on, but it runs and shifting perfect. I took it straight back and they plugged it in and the transmission guy said it was the same code as before. He said he thought it hadn't had the computer reset.
Does that make sense?
He reset it and also said, "drive it and if the light comes back on it might be the throttle sensing..." or something like that. My wife took it to town today and after about 90 mile (we live way out) the light came back on again.
It runs, shifts, and drives perfect, and just had a tune up about 200 miles ago.
Does it make sense that out of the blue there is now a throttle sensor issue, or did they put in faulty parts?

the high idling could be just the out side air temp. i live in North Dakota and when i start my car in the morning it will idle at around 1500 RPMs. you can drop the idle by taping the gas to snap it out of the warm up idle. it would do this when it is 30 degrees or colder it seems with my car at least.

I have a 2000 Bonneville that started out a few months ago when you started it you had to wait about 5 minutes before it would shift out of park. One day while driving down the road it just stopped working...it will run in 1st 2nd and reverse only. Does this sound like it needs to be replaced? The fluid is at the correct level and is pink. 165000 miles.

I'm having a issue with my car. When it warms up it begins to shift weird, mainly between 3 and OD. it will shift in to OD and the the revs will bounce. also wile going up hills in OD it will bounce the revs as little a 600 and as much as 1500 RPMs it seems like it wants to down shift but can't. If I let off the gas and then ease back in to it it shifts it self down to 3 and will cont with no problem. Any ideas?

Buddy: We had a 1998 B'ville that started slamming and missing shifts. The first symptom only occurred when turning right AND going slightly uphill. Sounds strange but as it got worse it slammed and shifted very hard after over revving the engine. Took a very bright service foreman at the Pontiac dealer (Same as Buick, Chevy, Caddy) to diagnose the external shift solenoid on the AT. The screens clog up after some time and even a trans fluid change does not always get it. They replaced the external solenoid w/o dropping the trans so it was relatively cheap (vs. $2000 or more for exchange trans).
If you get a good trans guy he will know about it. Yours may be an internal problem, that is more complicated. Good luck.

Last week, my car gave no warning & quit working! The motor locked up...there is no coolant in the oil. Someone thinks it might be the 'torque converter', any suggestions?
