I've got a beach cruiser with a T3 shifter. Can not get it to engage all three gears. Followed SRAM's online tune doccument and still can not get first gear (I think 1st). I shift into 3rd and adjust with plastic barrel to no avail. In 3rd and pedaling hub makes clicks while in rotation. In the next gear it is silent and then when indicator is forced into 1st ratio stays same as 2nd. Have tried tension tight and loose and still only two usable gears. What must I do the set it up to run all three speeds?
