Does anyone know the code for the computer prom numbers which start w/519K? For instance, mine is 519K 8226 2044 06630. this is for a 1981 Vette w/an automatic transmission. I need the PROm numbering for a four speed, manual 1981 Corvette to order a new PROM after switching from a automatic tranny to the Four speed. Using too much gas w/wrong PROM>
As always thanks. jim
