I use to do a lot of tranny work ( not you sick person you not that kind of tranny) and I used a TQ wrench on evry part during reassembly.. I have found that the best for the dollar low setting wrench is made by Snap-on.. Not cheap but well worth the money.. I have rebuilt over 200 tranny's and have yet to have one come back on a workmanship issue..
Mine is a 1/4 drive unit that reads inch pounds.. 12in pounds is equal to 1 foot pound so a little math is in order if your book does not give you a inch pound reading.
