Answer: You should have your automatic transmission serviced in accordance with your vehicle owner’s manual recommendation. There are also several things to watch for that will tell you your transmission should be serviced. You should occasionally check underneath your vehicle for any signs of leaking. The leaking may not be related to your transmission, but the transmission fluid should always be checked. You should also occasionally check your transmission fluid level and replace the fluid if it is too low or is too dark (transmission fluid should be red). If you experience any other problems with your transmission such as grinding noises or trouble shifting, you should have your automatic transmission serviced immediately to prevent your transmission from completely failing which would cause your vehicle to be inoperable.
