thank all of you who have been helping me get my truck equiped with the e4od , it went into limp mode, because the tachometer was not working.
so i changed the tach sensor----nothing
i changed the teca relay ---nothing
i chased the wires --no breaks
i pulled the cluster cleaned the connections-----nothing
changed the fipl-----nothing
changed the vass------nothing
switched the pcm------nothing
changed the trans control mod ---------nothing
what the f%^k
so i took off the teca relay again and jumped it from the power in to the pcm out ----- BINGO!!!!!!
the question now is why do they have the relay?
can i just leave it alone?
i just wounder how many guy's got trans rebuild because of that femal connection
