When there is a problem with a vehicle’s transmission, it show hundreds of symptoms. However, there are three warning indicators that you should constantly be aware of. Burning odours, transmission fluid leaking, and an illuminated check engine light are examples of these. If you discover a puddle of red fluid beneath your vehicle, it is likely that your transmission is leaking. If your check engine light flashes, it could be due to a transmission issue. In addition, if you notice a burning smell while driving, it could be due to unclean transmission fluid.
