    New Computer, and one that's relatively affordable.

    Sike, just found NickInTimesDesign reverse engineering work.

    I'm probably going to at least ATTEMPT to try and develop a homebrew TCU. But first, I'd like to have what the common issue with the TCU's, and what makes them $#!& the bed. Is it a hardware issue? Is it a software issue? Has anybody else attempted this? I am fairly new to this forum, and I'm sure a lot of you fellas have already looked at the threads way more than I have, but again, I'd like to troubleshoot the problem so I can decide how far I want to take this. If it works out, I'd like to post the entire process and open-source it so people don't get scalped on renix TCU's. A build list, an assembly guide, and a cost amount, assuming that this would come to fruition. Any help would be appreciated. Thanks in advance.

    I have a multimeter, 3D printer and a 3 speed manual jeep, I'll see if I can figure that out. Thank you!

    Trick question, it is NOT the same thing. I just forced it in there, now when I put it into D it'll start in 1st, but won't automatically shift. So I definitely need a another TCU.

    Yeah, it's teal. It does the same thing though, no? Would I be able to swap the connectors? Same voltage, same company.

    Also, I looked/cleaned/ all the connectors, no change. I got this new TCU relatively cheap, not really crying about it.

    So I have a TCU from a 90's jeep that I just got off market place. However, MY tcu said 86, although my jeep is a 87 (might have been marketed as such, and assembled in 86) and the TCU I purchased today, says 91. I've tried the connector for it, same pins, but there's different grooves. Will this work if I swap connectors? They look the same, they run the same voltage, I just don't want to install it and then @#$% something else up.

    I will give her a go, thank you man!

    Yeah I'm actively looking on here for a solid TCU troubleshooting guide. I appreciate the both of you for y'alls help! I'll look at both in the morning! While I was under there, I noticed one of the connections was cracked, not sure if it's holding continuity or not, but it doesn't look right so I'll end up replacing it anyway. Thanks again!

    Appreciate your suggestion! Can you point me in the direction of like a troubleshooting guide? I've looked at my TCU inside and out, and so far I don't see any burnt out capacitors/terminals upon visual inspection. Are there any good wiring diagrams? I've tried to look them up before but all I see are Ebay ads for people selling their's.
  12. SequioaMancheBoogers
    Okay, looked under there, found the selector switch, how do I go about troubleshooting this?
  13. SequioaMancheBoogers
    Checked that one as well!

    Thank you pizzaman09, do you mind elaborating which side? I apologize if it seems like I need my hand held, truth of the matter is, I do.
  15. SequioaMancheBoogers
    That was the first thing I checked!

    Hello, first post, before I discuss the issues, I've tried my best to look at most of the forum for a solution. I have an 87' Comanche, 2WD automatic, 4.0 inline 6. I was at the gas station, pulled in just fine, got my dranky drank, and when I went to pull out, reverse worked fine, put it into D, and I had no power whatsoever. I pulled my TCU out, and I still had the same issue, I have to manually shift it from 2-1 to D. And when put it in D, it starts off in 3rd, doesn't up or down shift. Reading online, I've seen a couple of things as far replacing the TCU, replacing that TPS, stuff like that. I have a new TCU lined up hopefully, however I just replaced the TPS after diagnosing the last one. When the TPS was relaxed, it was reading 4.8 volts. Switched out the new one, and the open throttle position shows me 4.8V. I guess my first question would be, How do I diagnose the TCU with a multimeter? How do I know if my new TPS was installed correctly? And is my transmission just shot? I've been after this for months, my mechanical knowledge extends to replacing an alternator on my dad's comanche, and an actuator, so I'm learning from scratch here. I'd appreciate any feedback, tips, etc.. Thank you in advance.
