has anyone got any info to putting a btr box behind a carby motor ,we have tried but having some problems if anyone can help,we are using a tcu from earlier falcon and set up a throttle body for the kick down input but we seem to be only getting 1st gear and reverse,normal limp mode i am told is 3rd gear so trying to pinpoint where problem might lie ,any help would be appreciated cheers

do you have a valid speedo signal present at the tcm?

we replaced the sender unit in the box cause we thought that might have been why we werent getting any signal ,but yeah i think that was one problem we were looking at ,not sure why we dont though could it be cheap electric speedo?
