somebody anybody PLEASE HELP!!!

[95knightridaz28]

ok i have a 95 z28 camaro not sure which transmission is in it but it has to be a 700r4 trans because it is reverse manual valve body.the error is since i didnt know it was reverse manual at first shifting up and down i set off the service engine light. and i got thes 2 codes
1. 84-third to second gear downshift feedback fault
2. 91-shift light fault

now my understanding i s these 2 codes go to a m6 car which my car never was as far as i know and a 700r4 not having the electronics anyways how would i or copuld i set off the ses light and how to fix it.
this is often refered to as c.a.g.s and the solution apears to be skip shift elimantor but that is also for a 6 speed car not a 700r4 as i have been researching . therefore any and all input would be greatly appreciated!!!!
