* Low transmission fluid level: Check the transmission fluid level and top it off if necessary.
* Dirty transmission fluid: Have the transmission fluid flushed and replaced if it is dirty.
* Faulty shift solenoids: The shift solenoids are responsible for controlling the shifting of gears. If a shift solenoid is faulty, it can prevent the transmission from shifting properly.
* Faulty transmission control module (TCM): The TCM is the computer that controls the transmission. If the TCM is faulty, it can cause the transmission to shift incorrectly.
* Mechanical problems with the transmission: If there is a mechanical problem with the transmission, such as a worn gear, it can prevent the transmission from shifting properly.
Here are some additional things to check if your Acura Integra's transmission is not shifting properly:
* Check the shift linkage: The shift linkage is the mechanical connection between the gearshift lever and the transmission. If the shift linkage is loose or damaged, it can prevent the transmission from shifting properly.
* Check the transmission mount: The transmission mount is the rubber mount that holds the transmission in place. If the transmission mount is broken, it can cause the transmission to move around excessively, which can prevent it from shifting properly.
If you are not able to identify the source of the problem yourself, you should take your car to a qualified mechanic for diagnosis and repair.
