cool ill have to try geezers method of flushing when i get the cash to do so. maybe for now ill just try the diesel fuel and drain it. ive got some left over from when you recommended the manual trans flush (worked great by the way now that im thinking about it I think the last full oil change on my truck was at 176K miles and I now have about 194k but maybe thats not all that bad since it sounds like xboxrox has done similar to me. there are definitely lots of snake oil products out there but i have been surprised at some of them working quite well. I used "Cataclean" in my Toyota Tercel to clear a P0420 code (catalytic converter inefficiency) and the code cleared itself in about 5 minutes!
