Had good intentions, and easy expectations but ended up compromising due to time and lack of tools. Attempted a flush of my 2010 Mazda 3 2.0L today. Found some new things I didn't notice since last flush. One looks like outlet line running from cooler has a leak. Will replace pinch clamp with crew clamp. Has a gash on line but no obvious leak coming from it. Dried out pink and white residue was all over cooler. Guess thats what Valvoline Maxlife DEX/MERC ATF looks like when its heated and evaporated. Also, found pan had a dent in it. No leaks from pan itself. Found out my 1/4" torque wrench is junk. I set the torque at 50 in-lbs. Is that too much for a 10mm transmission pan bolt? Well, this harbor freight torque wrench wanted to keep going and snapped the head off with the majority of the threads in the tranny. Any suggestions on drill bits, drills, extractors and taps? I had 9 quarts of Valvoline Maxlife ATF for the flush and 9 quarts of Amsoil Multivehicle signature series ATF for fill. After breaking bolt, and lacking the tools I decided to scrap Amsoil fill ($$$) since I will have to drop pan again to extract bolt. Thinking of replacing pan too since it was dented. Will also replace gasket again too. Ended up adding 6 quarts of Maxlife in. I did use Amsoil's Engine and Transmission flush first. Idled for 15 minutes, then drained right after, dropping pan, replacing gasket and filter. I got a Wix gasket and filter kit, since Amsoil seems to recommend Wix filters with its products. Feels better than the cheapest generic gasket and filter kit I got off Amazon. Surprisingly no leaks from that one bolt.
