Throwing Codes 700, 705, 976...

Hey since it's the weekend, the local shop isn't open so I was wondering if anyone had similiar problems or possible solutions to fix these codes.

Car has CEL/SES on and since I need to go through emissions test, I can't go in with the light on.

Originally thought it was from my aftermarket headers so I was just gonna do a sim/defouler or whatever, but after doing a scan, these errors came up.

P0700 - Transmission control system
P0705 - Transmission range sensor
p0976 - shift solenoid control circuit low


and before anything else, I just want to say that I had a 6spd swap done quite awhile ago, but never thought much of the light as I originally thought it was my headers.

any suggestions/solutions would be great so I can either try to diagnose it myself, or the local shop can.

Thanks for looking at the thread.
