Transmission Fluid in Pontiac Vibe continually dirty?

I just bought a 2003 Pontiac Vibe with under 60, 000 miles on it. The person that I bought the car from showed me documentation that the oil, air filter and transmission fluid had all been changed in August. I just took the car in to get another oil change and they said my transmission fluid was dirty. They even showed me it as it was being pumped out and comparatively it looked pretty dirty next to what was being pumped in. How can the transmission fluid get dirty in less than 3 months and very little mileage put on in that interval? Did the first guy not do his job? The air filter apparently also needs to be changed again. What could explain this?Transmission Fluid in Pontiac Vibe continually dirty?
Either the guy didn't do the job, got conned himself, or just had the fluid drained and not a full fluid exchange like you got. A fuild drain only replaces about 10% of the AT fluid. The mechanic drains the transmission pan and replaces/cleans the filter.There's still a lot of fluid in the transmission inner workings and even more in the torque convertor. SO, if you mix 10% clean fluid with 90% dirty fluid you would just end up with slightly cleaner ATF. It's always best to have a full ATF exchange. The price generally runs in the low 100s.Transmission Fluid in Pontiac Vibe continually dirty?
Because the owner didn't change it at 30,000 miles like the GM maintenance schedule told him (her) to.Transmission Fluid in Pontiac Vibe continually dirty?
a bad transmission fluid filter. tranny fluid filters are very small and can go out quite easily. buy one from advanced auto parts cheap and not so hard to replace probably not so hard on a vibe
