Anyone Siphon Out the ATF from the Fill Vent?
I'm thinking about doing a partial change out of the ATF in the Cobalt. In many of my AT vehicles I've used a pump with a thin long plastic tube inserted to the bottom of the tranny through the dipstick and pumped out the transmission fluid. Then I would add precisely the amount removed. This has always worked well for me over the years.
Has anyone used this procedure in the Cobalt (I realize the Cobalt doesn't have a dipstick, just a plug for the fill vent) to change out the ATF?
Any reason why this method wont work?
