so i just put my motor and tranny (th350) back together and in my Z... the car drove for about 2 or 3 days and then wouldn't go into gear anymore... i pulled the tranny out, and took the torque converter off and found two ground up pieces of steel under the input shaft, they look like some sort of key or boss that have broken off and been chewed up from the t/c spinning around the input shaft... anyone know what they are? where they came from? and do i need a new front pump? oh and the front pump was squeeking when i turned it by hand.... thanks in advance...
