If you are unsure of when to change the transmission fluid in your GM car, you can always consult with a qualified mechanic.
Here are some signs that your transmission fluid may need to be changed:
* The transmission shifts roughly or slips.
* The transmission fluid is dark or dirty.
* The transmission fluid has a burnt smell.
If you notice any of these signs, it is important to have the transmission fluid checked and changed as soon as possible.
