Hi everyone, I've searched but haven't found threads on this. I think I know the answer but just want to be 100% sure. On a 92 Corvette with the 4L60/700R4 do I need to get a tune when installing a higher stall torque converter? Thanks in advance

No reason unless it results in higher shift points and you hit the rev limiter (somethimes this happends.) Good luck

with 383Vett. Most often the only reason for a tune is due to cam change. You should be fine unless the shift points have changed drastically.

Thanks guys, its just that I had heard of the 4L60E guys having to get a tune so I was just wondering if us 700R4 guys had to. However I was confused because I thought that the 700R4 was not controlled by the ECM.

On a 700r4 the ECM only controls lockup of the torque converter.

You are correct. 4l60e guys need a tune above 3000 rpm stall.
ECM on a non-electronic trans only controls lock up.

Nice! Thank you all very much
