5 speed transmission on 2009 Mazda6 2.5 I4 has a sudden jerk into 4th gear when the car is cold. Started noticing this as temperatures in Canada dropped below Zero Celsius. Once the car is warmed up, the transmission shifts smoothly, but it is those first couple of shifts into 4th gear in the morning that are really bad. I have started using the manumatic transmission to keep the car in 3rd gear until it has warmed up slightly. Should I be worried, or is this a known "Feature" of this transmission

Hi All- I have an -07 6S Wagon (6 cyl) Back in late November, I heard a loud tapping/ticking type noise coming from engine upon acceleration. Also a rattle upon accelerating at approx 35 mph between 4th and 5th gear had been happening the last two months. Later in week; all of the engine lights came on and stayed on. After re-starting the vehicle; just the CEL stayed on. Took it to the dealer. They said two problems were ocurring: 1) DTC B1342 & U1900- they replaced the ABS module (under warranty) 2) They verified the tapping/ticking noise and the rattle upon acceleration. They didnt indicate any codes- but did replace the cat/flex pipe. All of this under warranty. I still hear the tapping/ticking noise upon acceleration? It is louder at different times than others- most noticeably obviously at non- highway speeds. A mechanic friend of mine who owns an '06 6S also- says this is valve tapping; he uses synthetic oil with an additive every oil change to quiet it down Any thoughts? Is this still a Cat issue? Should I bring it back to the dealer (again)?

Replying to: lg2207 (Jan 03, 2009 9:58 am) I'm also wondering if this is a common concern that other 3.0 S-engined 6 owners have experienced. I'd bring it back to the dealer to check it again while it's still under warrantee. I wouldn't wait. Maybe even try a different dealer.

Replying to: jkobty2 (Jan 02, 2009 10:53 am) Mine seemed smooth on the transition to 4th gear though. However, today (and I tried it multiple times) it did not shift into 5th until about 52 mph. One time it did along this stretch of flat road but several other times it did not. It is possible as most cars have that an adaptive algorithm is holding it in 4th that long? Or could it be a sensor or linkage due to the cold not allowing the up-shift as it usually had so readily?

Replying to: jkobty2 (Jan 05, 2009 10:36 am) I agree, I would prefer having a transmission without the adaptive feature. I would like to have switchable modes (economy, sport etc.). Heck, I am sure they could even throw in an variable control on the intensity of the modes. Now that I think about it, on that day I was pulling out of a parking lot onto a 6 lane road and had to stomp on the pedal going only about 15mph. It took about a 1/2 second for it to respond. Maybe that offset the algorithm. Does anyone know if there is anyway to reset the algorithm? |

| Hi again, anybody know why my 6's idling RPM ranges from 800-1800 and never runs at a consistant RMP? | |

Replying to: lg2207 (Feb 11, 2009 5:39 pm) Engine noise: A ticking noise from the 3.0L engine, often described as a lifter tick, requires the removal and reinstallation of the camshaft caps. (2003-05) Sound familiar?
