2002 LB7, slow speed going up a slight grade, going up my drive way, when it downshifts from 2nd to 1st, it flares up before going into 1st. Will spin the tires if its wet. Other than that the trans works great. Ideas on a fix? I don't know if the trans has ever had anything done to it. 224,000 miles.

Any ideas on this? If its under load when going from 2nd to 1st it really slams into 1st hard.
