All depends on what the little black partiles look like. Were you having trouble with the transmission before?
4 whopping cylinders on Toyota RV's. Talk about great getting good MPG. Also I have a very light foot on the pedal. I followed some MPG advice on Livingpress.com and I now get 22 MPG! Not bad for a home on wheels.
I never had any "particles" on either my (plastic end) tranny dipstick...or my all metal motor oil dipstick....altho I just had a JASPER tranny installed (4 grand, complete) when nothing happened when I put 'er in "D".

I used to have specks all over my dipstick on my E4OD, haven't paid attention to my current 06 tranny. Yes, the long tubes cause dirt to accumulate.
