T-56 reverse lock out solenoid with 730 ECM...
Is there anyway possible to add some code to AUJP and possibly add two pins (wires) to an empty spot on the 730 ECM's pigtails in order to get the T-56's reverse lockout solenoid to work properly?
I have two 6-speed 1991 Z-28's (one with a Hurst shifter, the other with a Pro 5.0 shifter) and BOTH are a pain in the **** to put into reverse.
I will say that the Pro 5.0 shifter goes into reverse a little better than the other, but it's still hard to do so.
Any thoughts on the above or is it even possible?
Is there a better solution?

I don't think there is any need to wire it into the ECM.

the next part is the reverse lockout.
if you look under the dash at your brake switch, you will see 3 wires. mine were yellow, somthing (red i think) and blue. connect a thick wire to either of the outer wires... i used 12gauge wire.. this wire will have power whenever the brake is on.
take one more piece of 12 gauge and put it to a solid ground. i used the same ground as somthing else used under the center console... its nothing more then a screw that goes into a piece thats spot welded to the floor... but its a good ground.
now hook the two wires up to the connector that goes to the reverselockout noid... this is the connector thats right next to the shifter on the drivers side. up at the top rear of the trans.
make sure nothing is shorted, then reconnect the battery.
with the brake off, it should be hard to put into reverse... if its not, shift thru the gears, then try again until its hard... you may have to rock the trans back and forth.
once its locked out and hard to shift to reverse, press the brake in. there should be a click, and it should go easily into reverse.
if it does not, you have the wires hooked up backwards... swap the wires where they go into the connector and try again.

Re: T-56 reverse lock out solenoid with 730 ECM...
If I wire it up like that, when I press the brake, the solenoid will engage and make it easy to go into reverse, correct?
But.... when I release the brake, will the solenoid go back to the park position making it hard to go into reverse again? Or, will it remain open and easy all the time to put into reverse?

Re: T-56 reverse lock out solenoid with 730 ECM...
Thats the way I wired mine too. Real easy to go into reverse when brake is applied, real hard any other time. Works great that way!!!

Re: T-56 reverse lock out solenoid with 730 ECM...
Well, when I originally posted this thread, I was wondering if it was possible to hook it up to the ECM, like when the VSS reads 0 (when the car is stopped), then power is applied to the reverse lockout solenoid via ECM. I wonder if this could be possible?
But, you guys are right, it's much easier to wire it up to the brake switch.

Re: T-56 reverse lock out solenoid with 730 ECM...
I would just wire the solenoid to a switch, like I did. I think the solenoid will wear out very quickly if it activates EVERY time you press the brake pedal, IMO.
How often do you really put the car in reverse? 1 or 2 times a day? I used a switch with a light in it so I can see that it is on or off.

Re: T-56 reverse lock out solenoid with 730 ECM...
it should last ok, the newer cars that use a shifter lockout activates it every time you hit the brake.
i think i have seen 2 that were bad.

Re: T-56 reverse lock out solenoid with 730 ECM...
I have mine wired to a button on my shifter ball. Works perfectly, and the wiring couldnt have been more simple.
You COULD always remove the solenoid and plug the hole. I dont really find myself shifting in a way that I could snag reverse very easy. Even with the solenoid released, you still have to push over into the reverse gate. I wouldnt hit that by accident while driving.
BUT...I still condone hooking it up to a switch...or the brake pedal. Either way... its a nice feature to have working.

Re: T-56 reverse lock out solenoid with 730 ECM...
sadly that was when I discovered a serious flaw in my wiring scheme.
Ah well the rest of the trans was worse off when I pulled it to rebuild.

Re: T-56 reverse lock out solenoid with 730 ECM...
I'll probably wire it the brake light circuit, but, I still think it would be cool to rig it upto the ECM when VSS reads 0 MPH.
Re: T-56 reverse lock out solenoid with 730 ECM...
You could wire it into both, that way you have to have the clutch and brake in at the same time to go to reverse. I doubt you'll go from 5th to 6th while braking at the same time all that often. With a good "notchy" shifter like a Pro 5.0 you shouldn't have to worry much about hitting reverse anyways.
There any details on this?

Re: T-56 reverse lock out solenoid with 730 ECM...
This has crossed my mind as well. I've even gone so far as throwing a few ideas together on paper, I just haven't gotten much past qualifiers. I've been working on commenting AXYC (since that's the version of $8D that I'm running.) It's slow going. The code shifts in a couple of different places and a lot of the labels in the ANHT hack make no sense to me. I figure I need to get my .bin commented out before I start changing things.....just wish I had more free time to get it done.
I did my T56 swap long before I started working with the programming, and I just took the solenoid apart and cut a coil off the spring inside. That cut the resistance down a lot but still left enough of a bias to keep from shifting 4-R by mistake.
JP shoot me a line if you wanna throw some ideas around.

Re: T-56 reverse lock out solenoid with 730 ECM...
(AUJP_Jp2.zip or something close to that)
Z69' and I found many things that are clarified in that document including the missing parts.

Re: T-56 reverse lock out solenoid with 730 ECM...
I've got a copy of JPAUJP that I'm using as a reference in addition to the ANHT hack. It's confusing at times trying to keep the addresses straight since there are code shifts between the 3 versions of $8D. Your hack has been a big help though, the RAM locations in particular have been proving useful. I've been verifying everything as much as possible just to make sure my AXYC is as accurate as I can make it.

Re: T-56 reverse lock out solenoid with 730 ECM...
I left the ANHT references in there to aid in following diffs between versions.
I'm interested to see what you find different in AXYC.

Re: T-56 reverse lock out solenoid with 730 ECM...
The code shift at the U5 A/D read routine is 88 addy locations between ANHT and AXYC. (F0D2 vs. F12A) I don't know where or why the shift is there yet, just that it's a fair chunk and there's more than one shift. The difference isn't that big in the middle of the code.
