4l60e stock settings

[RICHARDCRANIUM]

i just swaped a 2004 gto ls1 with a 4l60e into my 1962 comet.i used an ecu that was tuned prior and i cant seem to figure out how to make it shift right.i am hoping someone can send me a stock tune .motor is stock trans is stock convertor is upgraded but nothing fancy.if i drive normal its fine but if i lay into it it seems to slip going into 4th gear.almost seems like its in neutral till i lift of gas .i dont want to smoke this new trans.or if theres anyone in the kutztown pa area that i could take it too that actually knows what they are doing.
