Hi,
Thanks for your reply. Anyway, what I did was exactly as I wrote it. I backed-up original DDE ISN and did same for that of donor DDE and then wrote original DDE ISN into donor DDE and carried out CAS-DDE reset, then turned off ignition and allowed main relay to sleep and then crank and car started right away. My surprise was why it wouldn't shift gears. I intended to sync EGS-DDE but couldn't being 8HP transmission. Since it wouldn't shift gears, i returned original DDE back to car and did only CAS-DDE reset and car would start and shift gears normally. I think something else is left to be done which I would need assistance on. Ideas and suggestions are highly appreciated, thanks
