well i have drivin it for a week when its cold it shifts kinda soft like normal but doesnt wanna come out of 1st. then when its warm about 10 miles it flashed and shifts kinda hard and makes a high pitched squealing noise. I am going to hook my new scan tool up what codes might pop up? i know the incorrect gear ratio code means new tranny lol but would there be a code for a clogged filter. he may have some water or something in it i may drain it and test.
