I changed my trans fluid last weekend, using the conventional crappy plastic hand pump. I vowed to never use such a messy solution the last time I did my 4Runner. I'm looking for some good quality hand or pneumatic pumps for changing the fluid.
Please post links to different type of pumps, preferably not something that attaches to a 55 gallon drum!
I found this DIY using air pressure and a regular trans fluid bottle, seems easy enough, but still kinda high maintenance, a regular electric, pneumatic, or hand pump would be better.
