Hi Welcome to Just Answer!
P0700 is a general trans fault this code is used by the trans controller to tell the engine cotroller to turn on the check engine light you will need to get a scan tool to read the transmission codes to see what the problem is
i just scan and i get p0700
looks like tcm problem??
what kind of scan tool do you have not all can read trans codes
i have snap on solus ulthra
they dont show codes for transmission
ok that should be able to read the codes
i only have this code p0700
if you erase it does it come right back?
and transmission has no pwer
ok it sounds like you may have a tcm issue then but you may want to try another scan tool first just to make sure nothing weird is going on
the transmission Tcm is integrate on PCM??
if i change the computer i need to reprogramming?
at the dealer??
yes it will need to be programmed and also programmed to the sentury key system if it has it
this car has anymore computer for transmission or just the pcm??
no just the pcm
