after installing a line out converter in order to run an after market subwoofer and amplifier from the speaker wire on the factory amp, my car will not shift at all, keep in mind it is automatic but seems like it will not get out of first gear, it just goes straight to redline.. and when i put it from park to drive or any change like park to neutral reverse to drive, it bucks really hard.. i scanned my car since check engine light was on and i got P0715 imput turbine speed sensor and P0702 transmission control system electrical... we have since put all wires back to original and scratched the subs for now. but still no improvement... can anyone pleaasssee help, hope it not too expensive just paid for another semester at school...

thanks,

Jason
