Default Reverse Lock-out ??

Allright guys, I did a conversion and the only thing that we still haven't done, is the reverse lock out. I need to know what I can do to allow this feature to function normally, whether there is an electronic chip I can put in, or what? Thanks for your help.

Its something that is linked to the computor

there's a resistor or something that you wire to it and then to a button, say on a shift ****. i have the diagram and the gm part no. on the resistor or whatever it is, and i'll post it tonight when i get home

Here it is:
Reverse Lockout
The T56 uses an electically activated reverse-lockout solenoid that prevents the inadvertent selection of Reverse gear. The solenoid is located directly below the shifter. In the factory system,the computer powers the slenoidto allow selection of Reverse only when the car is traveling less than 5mph. While it is possible to "crash through" the lockout mechanism with brute force, the best way is to use a momentary push button switch located on the shift know that will power the solenoid whenever the button is depressed. Wirin the switch is easy, with power reacing the switch from the button while the other side of the solenoid is wired to ground. If you want to use the factory connector, the Chevy part number is 12101857.
Another interesting point that it brings out is that the T56 uses a synchronized reverse gear, which means it can be shifted into reverse with the car moving forward withoug grinding gears. but i would never try or recomend shifting into reverse while driving forward unless you know what your doing
this should help you

my bad, that's how you bypass it, to install it all you would need would be the gm part number listed above, but i don't know how/where to hook it up.

I wouldn't recomend a shift in to reverse while moving forward any faster than 1 or 2 mph.
That syncho is just brass and has NO clutch material.

what kind of car is this going in, if the car has a LS1 tap into the computer for the correct output.

if it does not what many of the mustang guys do with T56's is wire it to the brakes, as normally your going to have your foot on the brake,when going into reverse.

not the best way, but for a no hassle method, it works well for them.
