Color doesn’t always matter. You might decide to service the transmission. I would say change the filter and change the fluid and see what happens. You might add a quart of Lucas transmission additive into the mix and then drive it for 2-300 miles and see if it helps. Because I’ve done that personally on many cars. A lot of times, especially with GM product like that, that would solve it. Change it and put a quart of Lucas into the mix. If you need help with this, a certified technician, such as one from YourMechanic, can come to your home or office to inspect your car and service your transmission fluid if needed.
