Update.
Cars trans wasn't good lol. 1st was good, 2nd slipped bad, could only use 3rd if i activated passing gear (3rd worked good) otherwise went directly to OD, nothing would cancel it, OD slipped too.
Drove for a week, swapped trans for a unknown I got out of a field lol
This trans works great, 2nd is a little weak sometimes, 3rd is great, OD is Ok.
So now I'm 2900rpm at 85mph instead of 70mph

Downside, may be from this stupid cold front, I have been warming the car up. I lost 5mpg
