Need some info on an 08 TBSS 4L70E
Ok guys I need some help. I need to know which (if any) of the solenoids in the following schematic are activated when the transmission is in neutral. There is also one other solenoid in the second schematic that I have circled.
In the second schematic I need to know which (if any) of the 3 wires outlined in red, are switched to ground with the transmission in neutral. Thanks!

Cant do it like that in a TBSS. GM has an ECM OS for the manual Fbodys. There is no such thing for the TBSS. I have 2 ECMs installed now. Engine runs, all guages are working. I just need to wire in resistors to my tcm for the solenoids that it will be using when in neutral. Im just not sure which solenoids it uses in neutral.

Actually to keep the ECM from settimng a code during the self test on start up you would need a dummy there for all the solenoids. Still not so sure it wont set codes when the TCM sees the engine rpm rise and the MPH rise but the switch showing neutral . It may set a code for the switch being bad .
