My car has an automatic transmission.
Hello - there are a number of possible causes for this behavior, which I will list in approximate order of hassle and expense to check out: after making sure transmission fluid is at the proper level and condition (slightly pink, rather than dark, with no burned smell), make sure the overdrive override switch (end of the gear shift lever) wasn’t bumped, preventing selection of overdrive, check transmission fuses (overdrive is electronic on this one), check the transmission temperature sensor (won’t select transmission if it’s too cold), then have the solenoid for overdrive (or it’s wiring) checked. If no problems are found while checking these off, I recommend a transmission inspection performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, and give you an accurate assessment of damage and cost estimate for repairs.
