I bought one of the Harbor Freight [Pittsburgh Automotive - Item#69328] Brake Bleeder and Vacuum Pump Kits for $20 and I'm very happy with it. I did a transmission fluid and filter change, and line exchange on my 08 Liberty which doesn't have a dipstick. Long story short there are several sites showing the wrong chart for checking the transmission fluid level in that vehicle. Several are showing the NAG1 chart for the 42RLE and the charts aren't labeled. The NAG1 chat will create on overfill condition in the 42RLE, which is what I had. Not really a big deal since I realized it about 10 miles later when I spoke with my son's friend about the job. I needed to extract about a little more than half a quart of fluid. So instead of using my Miti-Vac I thought I'd try one of these. I wanted it to bleed brakes and this was the perfect excuse to buy one. It was well worth the $20 investment, and a tool which will get a quite a bit of use in the next few months. I'm going to get some new clear tubing and see if it can pull warm oil from the dipstick tube with it. That would make it a good tool for someone interested in getting a UOA sample halfway through an OCI vs. buying a dedicated tool for that.
