My transmission broke.
Hello, if is and automatic transmission, the fluid level should be checked first. If the fluid level is low, it should be topped up to the full mark and see if operation returns to normal. If the fluid level is good and there is still no transmission engagement, there may be some internal damage that has occurred. If this is a manual transmission, and when you depress the clutch it not engaging, you will want to check the clutch master cylinder fluid level. If the reservoir is empty, there is probably a leak present and that will have to be repaired before normal clutch engagement returns. If the reservoir is full, the clutch master cylinder or slave might have failed. If you can get it into gear and the engine revs up with any movement, you might need a clutch. I would have a certified mechanic do a thorough inspection of your vehicle’s transmission to see what needs to be repaired.
