    4l60 transmission question

    I just had installed a 4L 60 E in my 1995 Pontiac Firebird and the builder said the transmission had been gone through but now I get a code 83. I’m thinking this transmission is a 94 or earlier because I Ohm the wires out and I don’t see the torque converter PWM solenoid. It runs good and shifts fine but it sets the 83 code. My question is will this mess up the transmission if I keep driving it like this? Next weekend I’m going to pull the pan and find out but until then I was just wondering if it’s safe to drive?
