Hello everyone. I have a question that I did not find an answer to using the search function. I am just getting into prom tuning and decided to use tunerpro rt. I have the 16197427 pcm with the $0D mask. From what I have seen everywhere, that pcm with that mask and the BJLH bin should have an option in the flags to select a non-electronic transmission. However, mine contains no such option. I have downloaded the $0D .xdf file and the BJLH bin but the option just isn't there. Is this due to an error in the .xdf/bin/pcm combo I have or is it something else? If this has been answered else where, I appologize in advance. Please help me out.

.XDFs are rarely complete. They are created by users of TP RT, like you and I, from source documents or possibly some experimentation. There are also frequently multiple .XDFs, for the same code, so sometimes you need to find a second or third .XDF, to find all of the features you want or need.
You may also need to dive into adding that item to the .XDF, taking information from a "Hack", also called a "source document".

I just went over to moates and downloaded the only other two .xdf files they had for the $0D and all though they contain a LOT more constants, tables, and flags, I still cannot find the option for a non-electronic transmission. Would you be able to help me that flag from a hack? I looked up the hack at moates but I did not see the option I need in it either unless I don't know exactly what I was look for.
To add this in TP use address 0004
(because the definition already starts at $4000)
Use the "bit" code for bit #6, Save and use it.
If you are unsure of how to do this there is a good description in "help" of TP or the whitepaper on the site.
I am not totally sure that the option for the TCC is what I am looking for. I was reading through a post by Ben73 about converting from the 747 ecm to the 427 pcm. I know this has been some years but I wasn't old enough to drive at the time and didn't have the knowledge or the interest to do these things. However, now I do. Ben mentions there being a flag to select a 4L60 4L60E or a manual transmission in the hack. I will post the link to the thread for easy reference. It is mentioned in post #25.
My $0D xdf has this flag and everything else you will need all ready set up. It's available at Moates, titled Advanced 0D v175.zip. Check out the "Item Comments" for "Shift Light Enable", "Manual Transmission", "Torque Converter Clutch Only" and other transmission related items for more info on switching to a non electronic trans.
I had downloaded your version but I must be missing where it says item comments. By the way, great job with the file. It contains everything I will ever want/need to change. I just went back to the moates site and opened the zip file and only found the xdf, ads and xdf revisios history file. Is there something I am overlooking?
I guess I should explain what I am wanting to do before this gets too far in. As you have probably figured out, I am wanting to use the 700r4 with my 427 pcm until this fall when I get a 4L60E. I am not wanting to have the pcm control the lockup on my 700r4. I have had it wired without the pcm for quite some time. However, what I am wanting to do is make sure the computer can tell I am in park/neutral for idle purposes and I want it to interpret my vss appropriately. The park/neutral is wired up via a relay through the neutral safety switch since the truck did not originally have efi. The vss that I have on there is the one that the 700r4 used. I believe it was a 2,000 pulse per mile one. From what I read in the link I posted above by Ben73, he said he just switched the vss ratio from 40 to 2 pulses and it works perfect. Does this sound right? If I can get it to tell when I am in park/neutral and get it to read the vss signal correctly, it shouldn't matter what transmission I am using in the bin right? Just to make it aware, I have already disabled all 4L60E tranny codes until I get one. Is this all I should have to do?
Yes!
In TunerPro, up at the top, click on the View menu. Drop down to Item Comments and click. A screen will open at the bottom in the same place as the dashboard would be displayed while dataloging. Then open the "read me" at the top of the Constants list.
Thank you so much. This will certainly make life easier! So with this option checked, will the pcm still see the park/neutral switch and the vss function? (may sound like a stupid question but I just want to be positive for when I burn the chip)
