Ok, heres what happened.... I bought the k5 when it had a blown 700 and came with a 6 inch lift and 35's and with a spare np241, and a built 700 with corvette servo and shift kit with higher valve body pressures. We did the swap and ended up stretching out the kickdown cable because somehow it was overlooked in the unhook everything on it phase and we let it sit on the y pipe with the cable supporting it without realizing it(was dark outside). I went out and tested it after filling it up and 2nd gear shifted so hard it sqeeled the tires at barley any throttle and sometimes when i was completly off the throttle... eventually it would cause the demise of my stock 350 by blowing a main bearing. I had it checked out by one of my dads old buddies (the master mechanic) and he said it had a bad servo. I haven't gotten on the road yet because of money and intake gasket issues as well as registration and cali smog laws. My question is how will the stretched cable affect the operation of the tranny and was the hard shifting cause by the bad servo, the cable or both?
