* Worn synchronizers: The synchronizers in a transmission are responsible for matching the speeds of the input and output shafts before they engage, preventing grinding. If the synchronizers are worn, they may not be able to do their job properly, and the transmission can get stuck in reverse.
* Damaged shift forks: The shift forks in a transmission are responsible for moving the gears into place. If the shift forks are damaged, they may not be able to move the gears properly, and the transmission can get stuck in reverse.
* Bent shift linkage: The shift linkage in a transmission is responsible for connecting the shifter to the transmission. If the shift linkage is bent, it may not be able to move the gears properly, and the transmission can get stuck in reverse.
To prevent the transmission in a Mazda RX-7 from getting stuck in reverse, you can:
* Have the transmission fluid changed regularly: Fresh transmission fluid can help to keep the synchronizers and gears in good condition.
* Avoid shifting gears too quickly: Shifting gears too quickly can put extra strain on the synchronizers and gears, which can lead to wear and damage.
* Don't force the shifter into gear: If the shifter doesn't want to go into gear, don't force it. This can damage the shift forks and linkage.
If you are experiencing problems with your Mazda RX-7 transmission, it is important to have it inspected by a qualified mechanic as soon as possible to prevent further damage.
