Proud owner of a 07 black lux aft er a moment of insanity selling my 07 yellow lux... anyway...

Check engine light came on for a day then off... i stopped and had the codes run and got
740
785
2761

Reading the www it seems this is related to voltage with the tcc... possible due to the aftermarket alarm/remote starter that was put on the vehicle before I bought it...

Questions...

Can I fix this by disconnecting the remote start of the alarm system (python system)?

I am actually hurting the tcc or tranny with this setup?

Also, the red neutral light came on once (on the 4x4 selector button panel)... that I believe is the transfer case actuator... is that related more importantly is that a diy project?

Thanks in advance!
