So I decided to change the differential AND transmission oil in my car. It took me about 2 hours (yes, TWO HOURS !!) to complete the job, from warming up the car to sitting here typing this.
"How in the hell did it take you THAT long ?" you may ask.
Well,
(1) I usually wait a minimum 30 minutes to drain ALL the oil out, and
(2) The cheap-ass "shampoo-style" pump that I bought for $9 is THE worst "tool" I ever used. Every time I pumped down on it, about 1/4 of the oil (an exaggeration of course, but it SEEMED like it) that was coming out of the bottle leaked out instead of it going to its intended location. My garage floor was a complete mess after all was said and done. So about 45 minutes of the total time was used to clean up my mess.
That said, could you guys recommend me a decent fluid transfer pump for this application, preferable one that doesn't leak and cuts this job's time in half ??
