Thank you for your reply

I want to thank you for your support. I’ve been driving the car for a week and no codes. With every thing set on stock settings except for shift point it will break the tires lose when she hits...

Never mind I’ve got it. Thank you.

Thank you I will try that. So do I set all TCC apply rate vs gear vs % TPS to 124.5 and so on with the rest of them?

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...
