Slippery Pete recently had to change the transmission fluid on his weekend convertible using synthetic ATF. His ride just hit 30,000 miles and he likes to take good care of his baby. <br>The handy FLUID QUART PUMP screwed on the bottle with no problem. The pump worked great. He didn't have to worry about using a funnel and spilling fluid every where. He just aimed the flexible clear tube into the transmission and pumped away.<br>The best part is that he could easily control the amount of fluid being pumped and not worry about over filling.
