Hey. I own a 1992 K1500 and yes I know Im out of the league o Blazers but I need some info. The tranny (700R-4 non elecrtric) seems a little sluggish. I was wondering why guys perfer you not put a shift improver kit on these trannys? If I did install one would it help with its problem of being sluggish? Also whats the best shift improver kit out there cause Im not going to go the half ass way around if I do it. Any info would help. Thanks.
