the thing that puzzles me is why can i shft it manuelly and with a slight pause between 2nd and drive the trans appears to have no slippage. if i do this it when driving the trans takes drive and o/d great , will try new trans cooler today and see what happens , fluid is dex 3 and it looks good. previous owner stated that he had just had a trans service done 1 month ago . had it on the lift yesterday and checked for broken wiring to sensors , nothing obvious there , but will inspect more today and let you know. terra thanks for your help , i'm great with cars but this computer stuff , well lets just say i'm learning lol ,,
