I cant figure out why my 4l60 wont go into first when I shift into first, it shows me in D1 or D on the scanner but wont start out in first from dead stop , always starts rolling in Second gear. it will how ever start rolling in first if I go from park straight into 1st and it will drop into first if im rolling coming to a stop, but as soon as i stop it goes back to second even if the shifter is in first position. any help would be awesome. attached is my tune
your urban D1 upshift from 1>2 is being asked for at 0km/h and it also wont downshift from 2>1 in D1 urban until you stop.
would suggest making D1 Urban, D1, normal and performance values all identical.
look at your WOT shift points too. your asking for your 2>3 upshift and 3>2 downshift at the same time. the WOT speed values should be same as your normal, performance and D1 100%TPS column.
