I will be attempting to "fix/service" a 2004 Beetle convertible with the 2.0L gas engine and the automatic transmission (paddle manual shift option). I believe the transmission is the 09G model. I know you're supposed to use the VW european ATF in the car. But this was a $2000 purchase and has 150K miles so I'm not too worried about the transmission. The car starts and runs fine cold. Shifts well and does everything like it's supposed to. Once it fully warms up the ATF it starts shifting hard and all sorts of weird things...mainly due to common valve body issues these transmissions have once they have alot of miles on them. What I'd like to try is perhaps some ATF that exhibits the properties of the cold ATF when it's hot. The bores in the valve body get worn out and the hot ATF fluid thins out causing problems. Anybody know of any "shade tree" tricks or any type of ATF that will remain "think" as it warms up. I've read of people using MaxLife ATF in Beetles with great success. But thats on normal good running cars. I'm trying to mask a problem so I don't really care what type of ATF I use as long as it's thicker than typical once warm. The car belongs to a friend who bought it as a toy for the summer around town and doesn't want to start dropping $1000 here and there on a worn out $2000 Beetle that otherwise is a good car until the transmission warms up completely.
