I went ahead and checked my trans fluid while I did an oil change. I used the zip tie check bolt method. The black sludge is from sticking my finger against the side of the hole and the napkin is from the zip tie. Unknown mileage on fluid. Advice please, should I only do one drain and fill or do 3? It is hesitating sometimes from a stop and coast then gas.
