Thread: non-super 3.8 trans vs. supercharged trans?? Any difference

I Just have a few general questions. I'm looking to buy another car with the 3.8 motor probably 2001-2004 Prix or regal. From what i understand the transmissions are basically the same in the super and non supercharged besides the axle.

I have a 2001 non super 3.8 grand Prix that started making the usual whining when hot from what I believe bad solenoid. Then erratic shifting, (long shaft issue). I installed the transgo shift kit and have not had any more problems.


My questions are if I was to buy another car and the trans didn't display the trans issue when bought , would it still make sense to install the kit anyway?
Are the supercharged motors trans less common to have all these trans issues?

Thanks, i was hoping it wasn't the same. I saw a really clean car over the weekend. The trans fluid was clean but it was making the whining noise that is so common. It had 106,000 miles. I decided not to buy it. I didn't want those problems especially when its doing it from day one.

It was coming from the driver side, near the brake fluid reservoir. I always stick my ear to this area and listen. It got louder if you pushed on the throttle. The guy selling the car had no idea about the issue.

I have had 2 grand prix's and 1 regal that has did this and I always check that area when looking at the car.
