Even the dealer stated per quote, "hugh... that's funny"
and proceeded with a smile, stating we needed a new transmission...
it's the damn 3 wire splice, and the ground strap...!
it seems as though the error was an open circuit... shutting the TCM
off...
and the main system picks that as code 45... EATX Controller fault...
if the TCM does not have any power going to it, how the Beeep can the
thing control the Selenoid pack to shift...
at least this is what I am gathering...
although, as a test... I removed the EATX relay for a test run...
and it was Instantly in 2nd gear, from 0mph..
put the relay back in, and I got 1st and 2nd.. then a dump to neutral
and then 2nd gear lock...
I am going to test the whole thing out tomarrow, by removing the
ground strap... see if this old rebuild will dump to Limp Mode...
I'll let ya's know...
