hi, i did a tranny swap on my 1990 f250 from the auto e4od to the auto c6. the reason i did not use the same trans is because i just simple could not afford to rebuild it let alone purchase another one and i had the c6 lying around that was couple to an '83 carbed 460. what i was told i needed since now my truck only has 1st and 2nd gear is what's called a passing gear cable? i was also told it's called a kick down cable. which is the correct name? are there any other names this part goes by? this is the last thing i need on my truck then she'll be fine after 3 months of just sittin dead. is there anything anyone maybe suggest i do about this? i've already checked allllll the local junk yards, autowreckers, etc... and no one has it. any suggestions would probably hep, thanks in advance!
