Limp mode
I have a 09 equinox AWD and it's in limp mode and I have replaced the crank sensor cam sensor both transmission speed sensors tmc emc EGR timing chain and guides shift solenoids and tac doesn't work and it's in limp mode it's saying that there's no signal from output shaft speed sensor and I checked the wires it started out as a 2nd gear shift solenoid and I need help with ideas please

Can you be a little more specific please?
why?
what is saying? Please post any trouble codes you got.
what do you mean? What started out?

yeesh. Throw the odd period in this hard to read mess would ya.
How many miles on the transmission?
How did you check them?
I would get an electrical schematic (charm.li) . Measure resistance between the sensor and TCM connector with a multimeter. Ensure sensor has good ground and reference voltage (if applicable). If necessary, scope probe the VSS square wave signal at the TCM. If good signal is measure then it's a faulty TCM.
