Does your car have traction control?

Re: transmission
Check to see if the "cat" is plugged.

I have a '99 LTZ with traction control. Mine does this as well from time to time. Everynow and then, just briefly, the traction control light comes on. I have no cluse as to the problem. How would plugged cat cause this? It is something with a mechanical sound. It accelerates fine, just startling enough, you back off. Then it won't do it for a while.

Re: transmission
My 99 GT does this, and it has traction control. It's just the way the 4T65 transmission operates. Try accelerating hard once without the traction control on
 It's also not a good idea to accelerate real hard with the 3.8L motor. It has a lot of torque on the low end and can wreck your trans real fast.

Thanks BR.
I rarely drive the thing. I still run around in an old 180K 93 Astro. I have a '04 Avalanche, but rarely drive it. I will take the Lumina out for a spin tonight and into work tomorrow for the wife. She said she is noticing the traction control light coming on. Wierd thing is, I didn't know I had the option to turn it off. Will read the manual. She also said there is a whine coming from the right side. We have replaced the alternator before. I have a hunch that's what that might be. |

Re: transmission
You may not be able to de-activate the traction control on the Luminas. I don't know a lot about them, so I couldn't tell you for sure. In my 99 GP GT, I can deactivate it by pushing the TRAC button on the dash. There's one for sure way to do it though..and that's to pull the fuse

Hey thanks!
It doesn't do it much, but when it does it is startling. |
