I have Suzuki XL7 2007. It was fine but at a certain point the engine light came on. My problem is that when I drive, it downshifts while stopping at a traffic light or sometimes delayed shifting response from lower gears while accelerating or sometimes even random shifting between gears. For example, it sticks in gear 4 and when I try to downshift from that gear, it goes to gear 2. It skips gear 3. Could the PCM module or MAP to cause my Suzuki to skip gears when downshifting?
Usually, delay in shifting is caused by the clutch for those specific gears. However, other problems can also lead to this issue, like a leaking hydraulic circuit or a sticking spool valve in the valve body. Also, you may want to try checking the vacuum. If it fluctuates or has incorrect pressure, there could be your problem. This other post may help:
You may need to bring the vehicle for testing to identify the cause of the problem.
