Hello guys, maybe someone had this problem, and can save me some time. 98 2 door blazer, motor was blown, i bought it and put motor in it. went for test drive, wasn't shifting into second, at exactly 21 mph, if i let off the throttle, it will shift into 3rd,and overdrive just fine. went over everything i could check, and figured that second gear was just gone out. put in a new trans, take the blazer out to check it, and dangit no shift into second, same as before, over 21 mph, let off throttle, shifts right into 3rd and overdrive. GRRRRR !!! Then to add to my agony, my buddy needed a trans, i let him have my old one, and i'll be dam he puts it in his blazer and it runs perfectly! Every gear works perfect but second, it's like my blazer picks second out and just refuses to use it. HELP!! And no, it doesn't try to shift into second and rev up, like it's gone, it just refuses to use second. this is a new trans., and the one i took out works fine in my buddies blazer. Thanks.
