I bought a $6 oil/fluid pump and we seriously spent like one hour trying to get that damn thing to work. It was a peice of shit. We finally gave up with that piece of shit and went with the funnel and tube and got all the oil in in like 10 minutes.
So my advice to those wanted to change their oil: don't waste money on a damn oil pump, just pour the oil in the funnel and let the oil go through the tube into the car.
Also, the old oil smelt like shit.
Overall, shifting is much, much smoother. Tranny oil change is a must! Makes it feel brand new.
