    Tranny fluid change

    I did a full flush today at Pennzoil service station (similar to Jiffy or Mr. Lube or whatever other quick oil change places). They did a pretty good job. They have a special device that they connect to the bottom of the engine with 2 hoses. One pumps the old fluid out and another pumps it back...

    Odd purring sound after transmission flush and air filter change

    Not sure what caused this, as I did both at once. The sound is like purring. Sounds like I got a sweet cold air intake. But only between 1,000 and 2,000 RPMs. Only on D (Drive) and not on R (Reverse). Sounds both when idling and driving. Any ideas what can it be?

Found someone on classifieds selling rebuilt TCMs with 1y warranty with install for CAD$400. I know I can order on eBay for $300 and do the install myself...

    2008 Mazda3 Automatic, goes max to 3rd gear

    Three days ago I got engine light, but didn't have time to check. Yesterday, while accelerating rapidly there was a sound and felt it too. It was like something snapped. And then the car started maxing out on the 3rd gear. It was fine otherwise. Just won't go past 3rd. From what I read it sounds...
