Hi, I have an 07' sierra, 5.3 auto 4wd. I added a tranny cooler that has the low pressure drop feature (oil must be warm enough to go thru cooler). Anyway after adding the cooler I did need to add some fluid but am not sure if I'm reading the level correctly. It says to read warm , idling in park. When it is cold the fluid is well beyond the hot range and when it is warm and idling in park the fluid is barely above the low/cold mark. Prior to adding the cooler the cold level was near the cold mark and when hot in the hot range. Does adding the cooler change this reading in anyway and should I just be concerned with the level when hot? thanks |

I bought a 2004 Pontiac Grand Prix GTP (supercharged) 3 months ago. 80,000kms on it. Driving home from the lake today, passing cars at 130-140 kms per hour no problem. Get into the city, and my car starts rattling under the hood so bad. I made it to a local garage, fella there said the oil is fine,belts look fine, but it might be something very bad, that it would be best to take it back to the dealer. I had to leave it there, until I can have it towed to the dealership. No indicator lights came on, however, yesterday the car did tell me to check the trip computer. What's wrong with my car?

Replying to: angelarose1 (Jun 30, 2008 8:38 pm) Also the supercharger can go bad and I believe the front bearing area can be replaced separately if that is the noise maker. The oil in the superchargers should be replaced regularly to get long life out of them. Or you can just replace it at 100K miles or so when it goes bad. Guessing at what a sound that is a rattle without hearing it ourselves is difficult!
