Danny,
Can't help you much with your 3000. I know I had some problems identifying my 4000 as mine was made in the UK and the numbers aren't the same as the US made Fords.
I did get my 4000 in the shop last night. I got a 5 gal bucket of oil last night from Costco and will try to get the transmission filter tonight. Hopefully changing the filter, cleaning the pickup screen, and fresh oil will resolve some of the transmission problems I've been having.
