T56 Reverse Lockout with E-brake

T56 Reverse Lockout with E-brake
This is just to give everyone another option for hooking up the reverse lockout solenoid on a T56, that's using a PCM from a truck with a 4.8/5.3/6.0/6.2
The truck PCM's aren't wired for the Reverse Lockout on pin# 44 and can't be programmed to use it.
Sorry for no pics, but this one is really easy and straight forward.
WIRING ON SENSOR
A: LT. GREEN - Switched Ground with E-brake handle wire
B: PINK - Switched +12v with key on
I ran the PINK wire over to the Reverse Light Switch on the trans and spliced into the BROWN wire, which is switched 12v
I ran the LT. GREEN wire up by the shifter, drilled a small hole (use a rubber grommet), and spliced into the one wire going to the E-brake handle.
FUNCTION
With the key on and the E-brake pulled (just enough for the dash light to come on), the reverse lockout solenoid will activate and open the gate to reverse.
I've been running mine this way and it works really well. If I need to back into a parking spot, I pull the E-brake up one click to activate the dash light and shift into reverse easy peasy!

I just use a Hurst Line Lock button.... hit the button and both my line lock and the reverse lockout gets activated.. I have tried to use a switch between, but the switch I must have used, cuts the volts and it cause the line lock to not activate, so I just wire them together...

With HP Tuners 3.0 software and the segment swap functionality being implemented in the programs main interface you can segment swap over T56 transmission info from a Camaro in some applications. This will allow for normal RLO functionality.
However, this is a great alternative and nice write-up!

Most people use the brake lights
Tap into the stop light wire with the pink wire and ground the green. The rev lock solenoid is released when on the brakes. Most people already have the brake depressed when switching from forward to reverse gears, so this wont change driving style

The only other idea I had was to make a spring loaded, pull-up collar under the shift **** that would ground the circuit when pulled up. Much like a few cars have from the factory. Kinda like this:

Whats keeping you from switching PCMs? The classic 0411 box controls the function just fine and is a very similar pinout to most green/blue boxes
The shifter mounted switch is a nice idea, but you'll be flexing and bending the wires with every gear change. You worry about a dead solenoid, but wires can only be bent so many times before they break. They are metal afterall

I got reverse lockout programming working in my p59 Blue green truck pcm swap. I did have to do a segment swap with a manual trans segment to get it working. Now my pcm controls the reverse lockout and a shift light. This is the way to do it guys, there's no reason to do it any other way. Some will say that there is no manual transmission segment available for XXXOS, but there is always a way to hex edit a manual transmission segment into pretty much any OS as I am using a 2003 Suburban flex fuel OS with a custom manual transmission segment swap.
