I had a question, a friend was talking to me online tonight and he has a 91 firebird like mine and its an auto and he said he has a 4L60 and said it was the same as a 700r4. I was just lost cause I thought the 4L60 was computer controlled and in the 93-97 LT1 cars. He also said the 700r4/4L60 was rated to withstand 400lbs of torque. Just want some clarification here. Anyone help me out?

The 700R4 and the 4L60 are the same tranny. The 4L60-E is probably what you are thinking of they came in the f bodies starting in 94 and were electronically controlled.
