Seems like I am going against the grain but I would change to a 4spd trans, sure it is a bit of work but lots of trucks came with them so it is original equipt and lots of help here for sure and that way it will still be geared good for hauling a load especially the weight of a suburban plus you will get rid of the sucked out 3 spd. The extra gear is really nice. Apparently you don't like the 3spd anyway so nothing but better for you.
