#107 of 116 when transmission switch goes to back drive position - a laud snap by my_mazda

Nov 29, 2010 (9:30 am)

2007 Mazda CX-7, on a cold engine 1500 to 2000 rpm, when transmission switch goes to back drive position, a laud snap is heard. After couples of minutes of running engine and it goes from 2000 rpm to 1000 rpm everything is sound normal.
Is it normal behaving for Mazda CX-7? Does it mean I have to warm up engine for 2-3 minutes before start driving? (with my second car (Hyundai) I do not have this issue and can drive instantly.)

"..AT warning light.."
 
Usually means the transaxle is overheating...
 
"..bad cylinder..."
 
Solenoid, maybe...??
 
80,000 miles on an overstressed (F/awd) drive train...?
 
You're more likely looking at a rebuilt transaxle.

#109 of 116 transmission issues 2007 turbo cx7 by charlene1965

Over the last 6 months I have had some serious issues with my cx7 with the transmission slipping out of 6th gear and going to 3rd or 4th gear while driving on freeway . This is extremly dangerous as the cars decelerates almost immediately by approx. 20mph and I have almost got rear ended more than once. This is a random occurence, not going up a hill, not always in cruise and doesnt occur at the same speed every time. After the rapid deceleration and the corresponding rapid increase of rpms to over 7000 (high end of red zone) the car will now rapidly accerate like a rocket. This has also almost caused a rear end collesion. Mazda had been unable to duplicate this. To try to fix they have changed a few things, timing chain, o2 sensor and transmission flush. This has not fixed my problem, still happens. I purchased the exteded warranty but have still shelled out 750 bucks without the problem being resolved.
Do you know if this is a commen issue with this model or if I maybe just have a lemon. I have approx. 70,000 miles on it.

Knock/ping sensors...
 
Or second possibility is intermittent transaxle output shift rotatuinal speed sensor.
 
Engine/transaxle ECU "detects" knock/ping, thinks it's due to engine lugging, DOWNSHIFT, QUICK....
 
Knock/ping detection disappears and car goes into "re-acceleration" mode.

#111 of 116 Transmission jerks by aburroughs

Hello all....I have a 2007 CX-7...recently the vehicle feels like the engine had a miss. Took it to a dealer and $641 later after a new battery, air filter and spark plugs it still feels like a miss. Took it back and had them test drive it with me and of course it did not do it. I could feel it but they could not. Took the car back a week later and left it for the day. They still felt no miss..or jerk. Thought I was crazy and left it with my father in law for a weekend and he noticed it immediately. He took it and had the auto-transmission flushed. Still jerks. Mostlly around 45mph and up 4, 5, and 6th gear. Just went and got an extended warranty cause I feel I'm in for it. The dealership ended up telling me that before it gets worse they could do nothing. I'm not getting any warning lights at all. Has 51,000 miles on it. Any suggestions of what to do now? It feels like it is getting worse. I guess taking it again to the dealership and leaving it until it does the jerking for them is my next option.

I finally with my extended warranty got a new transmission after MULTIPLE trips to dealer....paying MULTIPLE deductibles to my extended warranty protection ($200/every time). The replaced timing chain....( I guess they knew this was an issue with this car), transmission flushes etc. I took it to a different dealer who couldn't find anything wrong with it either...they thought I was trying to scam Mazda. It took for the transmission to sieze up on a drive with the mechanic at dealership for them to believe me. Keep on pressing it, it sounds like the same problem I was having and eventually, it will become evident. Thank goodness you purchased the warranty. The jerking got so bad I almost got into a few accidents as it would deaccelerate (felt like a downshift) on the freeway at 70mph.... Good luck.

I am having the same issue with my 2007 CX 7 -- jerking when automatic transmission shifts from 1st to 2nd -- did you have that repaired? What ended up being wrong with it and how much did it cost?

I noticed that others have had this problem -- Jerking when automatic transmission shifts from 1st to 2nd. I have a 2007 CX 7 and it just started doing this. No lights indicating any problem and my mechanic got no readings during diagnostics. Has anyone had this problem assessed, fixed? What did it turn out to be? How much did it cost? Thanks so much for your help! I look forward to hearing from someone, anyone? Have an awesome day!
