Manual says change tran. fluid at 50,000 miles with heavy towing. Should I change it even if I don't do heavy towing. I drive mainly city miles
50,000 mile maintenance on 2004 Pontiac Vibe
I would definitely change it if it hasn't been replaced before. Have the fluid and the filter changed (if applicable). It's a good idea to have the fluid flushed out of the entire transmission, trans. cooler and the torque converter as well. If you plan on keeping this vehicle and want it to be reliable, this will really help. Make sure to use a good quality, approved transmission fluid for this transmission.
change it i always say is better to be safe then sorry
