I have same problem face on my car mazada 3 2007 I was change oil and filter for gear but same problem at light coming singe after car still on 4 gear when I off car then again start then it's k for 2 minutes then again same problem

I know it has been a few years, but were you able to identify and fix the problem?

Happened to me once but it went through a s setting period not drove much. One owner car. I rest the car using the ignition key only. Went away car now drove every day now all good 👍🏻

ECM issue...

what is the solution on this pliz am facing the same problem

Check nuetral park safety switcht

Dude I have the same issue, and that happened for the first time frs. This is the first time i had issues with my car tbh

I'm also facing the same problem. Would like to know the solution to this problem. Thank you.

Yes mind stop going still shift but want go

I read codes it said shift solenoid a so i replaced the shift solenoid new filter and fluid still the same when i put it in gear it shifts harx in reverse or drive ade drives good just cant go past 3rd gear soreplaced both shift solenoids and new fluid and it's still doing the same thing I guess i I'm going to replace the tcm

Transmission control module, replace it

Transmission going to give up soon

Change tcm and check may be you will not face this issue

Did you find out was this TCM I replaced and still issue

At module

Whts the reason of the problem

I am having this problem now, and it all came back to the TCM

Same problem I am facing mazda 3

I’m having this issue now kinda sad but thank you for telling us what the issue was

I have experienced the problem and changed my tcm but the light keeps coming back on and off

Sometimes it's the throttle body, if it's to dirty I will cause the transmission to shift way weird. Replaced mine and it got way better but still a little off though.

Going the same thing with my 2007 Mazda 3 currently leaking something assuming transmission fluid

Damn this is me right now. Bringing it to the shop this weekend.

i have the same problem but with a mazda 5, if is really cold it will turn the AT light but if i let it warm a little and turn it off and the on again it will go away

Mine is doing the same problem no lights on the dash tho and my cruise control isn’t working anyone know what it could be

I’m having the same issue yall ! I’ve been driving it like that because it’s my only transportation but it’s SO dangerous ! So let’s say I turn on my car, light is off, then I drive it a bit and it kind of brakes super quick and slows down to 5 miles per hr or sometimes it dies. Sometimes I have to keep pushing the gas and it’s a constant go and brake by itself 😭 or sometimes when it doesn’t go I just have to stop turn it off and on.

i have the same problem but the AT light is next to the park symbol on my 2012 mazda 6 i replaced the tcm put transmission oil and replaced the speed sensor but still no luck anybody can help me ?

My car had the same problem

First day spaced three 100 mg pills 4- 6 hrs apart. Didn't notice anything. Second day started with 200 mg felt it immediately about 15 min in and had general feeling of well being. Visited with my sister and mom and I truly saw the benefits. I didn't stutter, I stayed on topic, instead of jumping back and forth and I didn't have to go Into details or stories to explain one point. My ADHD causes me to trip over words, I talk way to fast normally , and I forget what I'm saying mid sentence because I go off topic and im easily distracted. This supplement , these lil ol pills helped me communicate like a normal ass person for once in a long time. Only thing I wish I could have felt was the physical stimulation, because I'm looking for more drive and motivation...to get more organized and do the things I need to do instead of waiting last minute.

Check out the transmission fluid my was very low when the light came on

mine was the speed sensor. easy and cheap fix

I have the same problem, to ne honest I have zero knowledge when I bought my car (2nd hand) and I thought it's just normal that AT is displayed since it is set to automatic mode. But im driving it for more than 6 months already and not getting any problem so far.

Transmission control module is going bad

First check transmission fluid ,if it's dark change it but I'll advise changing the transmission shift solenoids if you changing the transmission fluid. NOW IF IT DRIVE FINE IT COOL BUT IF DAYS LATER THE PROBLEM come back check the fluid and if it's dark that's signs of a burnt up transmission. Mazda 3 automatic transmission do not holdup long. Normally the transmission go before the engine. Also keep in mind the transmission fluid need to be changed bout every 3months

Phenylpiracetam/caffeine and Oxiracetam/Ephedrine are my two go-to nootropic stacks for studying 📖.

I see your tire pressure sensors are on, get some aftermarket sensors, have them reprogrammed for the car and throw out the old ones after reprogramming the new ones or keep them for future if programming should be needed. That oil filter is BS compared to other cars, but have the filter changed and put some fresh oil in there and that should take care of all the lights on in your car.

The car's indicates that the AT light means Automatic Trans-axle. The transaxle works as a differential does on a rear wheel drive car, but for front wheel drive cars instead. I have the same car and I have had the same symptoms that you're experiencing. I had a really bad axle problem and had to have both axles replaced. once replaced the shifting problem along with the torque loss was also went away but slowly came back. Bad transmission fluid seems to be my issue. You also want to replace it as indicated by the manual. However; I am steering down the barrel of a new transmission or a complete rebuild. Knowing myself, a rebuild to me means replacing all internals and externals. (Hub and wheel bearings, both axles, transmission mount both upper and lower.) Anything that plays a role with the cars drivetrain. I might even throw in a new torque converter if the transmission repair guy deems it.

What is the use of numbers above the Kilometres?

Same problem I'm facing.. I drained the gear oil but AT light still comes on. What could be the problem?

You ca reset your TCM and replace your oil filter. I have also the same problem

I’m having the same problem the exact same problem and idk how to fix it

Mine is doing same after a new Gear Box was put in.Turns out on mine its a "Speed sensor issue" cheapest part of all the problems these mazda 3 have. Good way to see if Box is ok drive in manual mode if changing up and down ok its electrical not a faulty box. Get a good mechanic to see what code comes up on a scanner.

This is a common problem with the transmission on Mazda vehicles. Replace the TCM and you are good to go....

I have exactly the same issue. I used de OBD scanner and it shows shifting solenoid. But you said the AT module solve your problem right?

Do you happen to know who made the Sports Automatic Transmission for the Mazda 3 SP23 First generation (BK; 2003-2009) using Mazda L (L3 SVT) 4 Cylinder, 2.3 Litre engine? Is it a Jatco Transmission?

Same problem as the video exactly idk wtf is wrong

Kindly mention the name of hotel brother thank you

Check codes, maybe speed sensor or another one gone bad

Finally a honest review thanks I was gonna waste my money on this stuff but now am thinking twice

I have the same problem with Mazda 3 sport 2007. No signs of any issues. Just came out the next morning with the AT light on will reverse but won't go forward
