IDK what to think about this 91 corvette LS swapped running a 4l60E and a 99 PCM.
I was doing some spirited driving this weekend. I got a CK eng light code P1810 and my car will surge above 73MPH. It feels like its downshifting. I cleared the code and it did not come back but it will still surge.

Do you have HP Tuners or something similar to run a log? HP Tuners can log all sorts of transmission parameters to troubleshoot what is going on.
When I looked up that code it mentioned maxing the line pressure as part of the "limp home" effect. Does it shift differently than normal?

I don't know what normal is, I just got the swap done a few weeks ago. The funny thing is it only happens at 73 or above otherwise it shift and acts just like it has been for 2 weeks. If I hold on the brake it goes out of lockup and stays there. Maybe I have a bad Lock up switch? I don't have HP tuners.
