4l80e swap now my truck runs terrible.
I finished my 4l80e swap over the weekend and now my truck runs like dog ****. I haven't done the segment swap yet because I don't have hptuners. My truck is supposed to go to the tuner for the swap and tune on Sunday.
It idles terribly and dies.
I used a speartech swap harness (4l60 to 4l80e).
Is this normal to happen before the segment swap?
The truck wasn't running "great" before the swap. But it would idle all day without hesitation. Any help is appreciated.
