4L60e- 4L80E trans swap

I changed my 4L60E transd for a 4L80E and did the wire conversions, but now when I get up to 6mph my truck Cuts out and dies. What could the problem be?

Welcome

Was the 4L80E segment file added to your existing tune?

There are several sponsers that can recalibrate your ECU for the swap.

Black bear

I'm going to make some calls to them tomorrow. Thanks. I read about the relay, but I did not understand it too well. I'd be better off leaving it to the pros.
