Common Mazda MPV Transmission Problems Everyone Encounters
Whenever you sense that something is wrong with your car, try to diagnose the problem immediately. And it should be corrected right away. If you are facing Mazda transmission problems, then you must identify the faulty transmission symptoms first. So now you can get them checked by a mechanic or fix them on your own.
Problem 1: The Reverse Gear Won’t Engage
The transverse automatic transmission system often cannot engage the reverse gear. It’s a common issue in Mazda Mpv models which use 5F31J 5-speed. This is a common occurrence that is initiated by changing transmission fluid. Forward gear changes remain the same, and it does not affect any other operation.
Causes and solutions
- This can occur due to the removal of the band anchor stud mistakenly during changing the transmission fluid. This is because of the similar appearance of the fill plug and the anchor stud. The reverse band assembly is freed. As a result, it stops the reverse gear from being engaged.
- Pay attention closely while the transmission fluid is being changed. The fill plug and the anchor stud should not be mistaken as similar. Be careful so that the band anchor stud remains right where it is. For example, you have to be careful while plugging a brake line while replacing caliper.
Problem 2: Transmission Slips or Shifts Hard
This is a common issue in Mazda vehicles with transverse 4-speed automatic transmission. It starts with gears slipping to erratic gear shifts. The car gets heated up during hot weather leads to this situation.
You’ll see that the overdrive indicator starts giving signals by flashing. The check engine light gets triggered and illuminates. It rarely happens or gets solved by default when in cold weather.
Causes and solutions
- There is a neutral safety switch in the car. When it fails, the transmission starts slipping. The information regarding the location of the gear selector is known through this switch. Now TCU gets the wrong information about the gear selector. As a result, the shift pattern gets disrupted.
To get rid of this problem, the switch should be replaced.
- The connector on the neutral safety switch gets loosened sometimes which is also a major reason. It can also occur due to damaged wiring. Proper observation and check should be done to find out the potential issues.
Problem 3: Failure of the 4th And 5th Gear Or Rough Transmissions
Mazda MPV models with 5-speed automatic transmission have difficulty activating 4th and 5th gear. Often this also leads to other gears being erratically changed and delayed.
At first, this issue mostly shows up when the temperature is below 5. The problem persists and pops up consistently. The check engine light gets triggered for which the following codes are preserved on DTC memory
Causes and solutions
- Breakage of the spring that controls the pre-stroke valve in the fourth gear. The 4th gear cannot be activated as a result of this. P0734 and P0735 codes will be available in DTC memory. Upgraded replacement kits are the best and most reliable solution to this common issue. It will help in engaging the 4th gear better.
- The valve body is excessively worn or the solenoid is stuck. This leads to the loss of transmission fluid pressure. Unintended and harsh changes in gear are observed because of this. Nonetheless, the check engine light is not triggered in this problem.

Problem 4: Failure to Engage Overdrive Gear
Overdrive gear engagement seems to be a typical issue with Mazda that uses 4-speed automatic transmission. It’s curated and positioned longitudinally. When overdrive gear fails to engage, it automatically results in a shift to neutral.
At first, the problem will show up only when the temperature gets cold. But with time it will become more prominent. The rest of the gears on the car keeps working perfectly. The dashboard also does not show any warning light.
Reasons and Recommendations
- The servo pin has worn out or excessive clearance within the bore. Transmission fluid pressure can be at loss due to these reasons. And it just gets worse with time
The best solution to this problem would be to replace the sealing ring and the pin. Upgraded pins are easily available in the market as this is a widespread problem.
- Another reason can be the clip that holds the servo being broken. Failure to engage in overdrive will get permanent and can happen instantly if this problem arises. Look out inside the valve body to find out if there are any metal parts in it. This is the most convenient way to figure out this issue.
These are the 2004 Mazda MPV transmission problems that are very common among users.
