What are the DTC codes related to Mazda 2 transmission problems?

P0766 – Failed Shift Solenoid D – This DTC can be stored when there is a problem with a shift solenoid or the valve body.
P2703 – Failed Friction Element D – This trouble code can be triggered by a failed friction element like a clutch disc.
P0720 – Failed Input Speed Sensor or Output Speed Sensor – This trouble code is caused by a bad speed sensor on the transmission.
P0730 – Incorrect Gear Ratio – This issue could be caused by a number of problems, including a fault in the transmission control module, dirty transmission fluid, or a bad transmission solenoid.
P0657 – Voltage Problem in the ‘A’ Circuit – This transmission problem is often caused by a short, or bad ground on the PCM or PCM wiring harness.
P0700 – Malfunction in the transmission control system – This DTC is often triggered when there is a problem with the TCM, a wiring harness, a solenoid, or the valve body.
P0715 – Input/Turbine Speed Sensor Malfunction – This code typically gets stored when the input sensor cannot read the engine RPM, which can prevent the transmission from appropriately shifting gears.
P0717 – Input/Turbine Speed Sensor No Signal – This trouble code is generated when the PCM does not get a signal from the input speed sensor, which will prevent the computer from being able to determine when the transmission needs to shift.
P0791 – Intermediate Shaft Speed Sensor ‘A’ Circuit – This error can occur when there is a problem with the intermediate shaft speed sensor, most likely due to a bad sensor, wiring problem, or a failed shift solenoid.
P0793 – Intermediate Shaft Speed Sensor Circuit No Signal – The computer will generate this DTC when it cannot communicate with the intermediate shaft speed sensor.

Can I drive with a transmission problem?

If your Mazda 2 can still make it up and down the road, you might say “It’s fine, I’ll just drive it until I can get it fixed”. But that is not always a good idea, depending on the symptoms. You see, there are a lot of (very expensive) moving parts inside of a transmission, and if something isn’t right, continuing to drive with a transmission problem could damage something else.

How often does a Mazda 2 transmission need to be replaced?

The overall lifespan of a Mazda 2 transmission largely depends on how well it was maintained. Factory design flaws also factor into this equation, along with how/how hard you drive. But on average, we’ve seen the Mazda 2 transmission last for between 130,000-180,000 miles. A high quality replacement transmission however, can last considerably longer if all of the factory design flaws have been addressed and the vehicle has been maintained.

How are Mazda 2 transmission issues diagnosed?

It is fairly easy to guesstimate what the root cause of your Mazda 2 transmission problems might be, but you won’t truly know unless you have the right tools and experience. A good mechanic or transmission repair center will be able to connect your truck to a computer and find out which diagnostic trouble codes (DTC’s) have been stored. Once they know what to look for, they can perform a visual inspection to verify the problem.

How is a Mazda 2 transmission replaced?

In order to replace your Mazda 2 transmission, the truck has to be lifted from the ground in order to gain access to all of the parts that will need to be unbolted. Then the transmission can be lowered to the ground (typically with a transmission jack), so the new transmission can be installed. Once it is in place, for the 6L80, the vehicle PCM will have to be reprogrammed / reflashed to accept the new transmission using the latest GM subscription.

How to Solve Mazda 2 Transmission Problems

Solution A: Buy a Used Mazda 2 Transmission

The quickest way to fix your transmission problems is to simply buy a used transmission or used transmission. These can be found at most junk yards, and they often come with a 30-90 day warranty. However, there’s no way to determine the actual condition of the internal components, so you could be spending a bunch of money to have the exact same problems. Plus, that warranty only covers the transmission if it’s defective, not the labor costs that you’ll have to pay.

Solution B: Buy a Rebuilt Mazda 2 Transmission

Another option would be a rebuilt transmission or rebuilt transmission. A local repair shop will remove your transmission, then install a bunch of new parts during the rebuild. The problem here is, the skills and experience of each transmission rebuilder will vary widely from shop to shop, so you could have problems from something that wasn’t adjusted properly. And the 1-2 year warranty might only cover you at certain transmission repair shops, in a specific geographical area.

Solution C: Buy a Remanufactured Mazda 2 Transmission

Many owners depend on their vehicle to commute and get things done. Their gasoline engines are designed to go 100’s of thousands of miles, so it makes sense to invest in a remanufactured transmission.

Mazda2 2012 only 34,900 miles, one driver gear pops out of 5th gear. Other gears seem to be fine. I am taking it in to be fixed. What could the problem be and how much might it cost me. I live in the Central Valley, CA

My Mazda 2 Genki, auto, done less then 5000ks. Whilst driving the accelerator totally losses power whilst in mid drive, leaving me with a motionless car, causing headaches for the poor people behind me, I was once in an intersection – motionless, the dealer has had my car thus far for 9 days and they say they haven’t had any other cars doing this and won’t fix it till they actually experience it with my car. Has anyone had this same problem?

Got the error codes P0771, U0155, and U0121 on my 2014 Mazda 2 with only 75,000 Miles on it.
What’s most likely causing this and how much should it cost me to fix?

2017 Mazda 2 has developed a whistle in the automatic transmission when shifting up from 2nd. and 3rd. gear but not at any other time. Mazda claim that they can not detect the problem even though they have replaced the original gear box with a similar problem that has a whistle between 1st and 2nd. The car has only traveled 7000 k/m.

Mazda 2 auto tranny are known to have whistling noise when downshifting. This is absolutely normal due to the pressure changes when the solenoid engage and disengage. However do look out when your shift suddenly goes sluggish or delayed in response of the shift. The tight transmission fluid passage in Mazda gearbox are notoriously easy to be clogged and the solenoid / tcm will misbehave when the temp around the gearbox or engine bay raises. Investing in a good transmission fluid cooler is the first step to prevent trans damages in Mazda.
