Manual valve body 727 - 3rd gear won't engage under full throttle

or ur shift linkage could need alittle tweaking.....Did u use a new gasket and seal kit when u swapped the guts, r the bands set right, what r they set at, did u transfer the front servo, and is it the controlled load servo. which is 71 up or the 70 down front servo, how many springs in it, what is the front servo lever ratio and lastly did u happen to break a sealing ring on the pump..............kim.........
