car doesn't start becuz of auto tranny signal

[silversr]

Ok i swapped in a ka24de into a freinds 90 240sx everything is hooked up right but it doesn't start so i did a self diagnostics and code 54 came up auto tranny signal:tweak: i was like wat the fuck it has a 5 speed in it please someone help

[mjjstang]

was it converted from auto? did you swap ecu at all?

[mrmephistopheles]

probably didn't close the auto signal loop.

I swapped in the number 28 ecu,the car was originally 5 speed unless someone changed it

Im no ecu expert but maybe someone here knows about that 28, Like MrMeph was saying, theres a set of terminals you must jump over by the battery on auto cars when they are converted to manual. but if you say this was originally a manual transmission car (and still is), and assuming it has the same harness, then that should not be an issue, I donno sorry.
