1996 Honda Accord torque wrench

i m working on an automatic transmission when i tight 10 mm head (6*1.0mm) valve body bolt to 8.7 foot pound the wrench does not click i tried all the 10 mm of the valve body it did not click however the wrench clicked when i torque 12 mm head (8*1.25mm) to 13 foot pound or less. the 10 mm head bolts are long and when i tight then they squeak i put transmission oil on the treads and head same they squeak and i do not hear the click or feel it . what could be the problem?
