my car is an automatic. i have park, neutral, reverse and low drive.
it wont shift as i accellerate. i di dthe ignition code thing and
came up with 1-2-3-7-5-5. can anyone help me? keep it simple cuz im
not very car savy. thanks.

 

I'll be the pauses between the codes work out to
1-2---3-7---5-5
Thats 12, 37, 55. 12 is "start of codes" and 55 is "end of codes"; 37
is

37 Torque converter unlock circuit open or shorted, A-413 4-speed auto

according to my code sheet. So... it's telling you that the control
for the lockup torque converter isn't working right. Are you sure
you've only got first gear, or is it possible you've only got second?
That would be consistent with it going into "limp-home" mode.

 

joe? thanks for your response. could you please help me a little
more? what steps do i need to take to fix this problem? approx. cost?

 

Either get a factory service manual (not Chilton's, not Haynes,
factory) or talk to a mechanic. From here, I'd have to start tracing
wires and do a real diagnosis -- it could be anything from a loose
connector that would take 30 seconds to reseat to (if the solenoid is
internal to the trans; I don't know) something requiring pulling the
transmission out. So cost could be anything from "virtually 0" to
"buy a new car".
