    94 4l80e limp mode

    Replaced all of the shift solenoids and that corrected the problem, I just sold the truck last week, I sold it to a friend so I am sure I will hear about it if they give him any problems.

    94 4l80e limp mode

    I haven't given up yet just been too busy to mess with ol red thunder, it's just a farm truck and not my daily so it's not hard to just put it on the back burner. I will be sure to keep this thread updated with my findings. I am hoping to work on it next week.

    94 4l80e limp mode

    The one thing that has me puzzled is why will it reset and work fine for 10 minutes then go right back? It’s like clock work I would think if it was a wire short it would be a little more sporadic and intermittent. Is it possible that a failed solenoid would behave like that? Maybe the vss? I...

    94 4l80e limp mode

    I was wrong yesterday I thought I lost power at the fuse when it went into limp mode, I was testing it and there wasn't any power until I reset the truck. I guess my tester didn't have a good ground while I was testing continuity. I thought it had to be the ignition switch as that was a common...

    94 4l80e limp mode

    So I hooked the battery back up all codes were cleared. Drove to town and back and when I was just about back home it went into limp mode. Checked and I didn’t have power to the fuse. With the truck running I pulled the fuse and put it right back in and it was powered again. Same issue though...

    94 4l80e limp mode

    I was busy all weekend I left it sitting with the battery unhooked for the last few days I am going to work on it again tonight. I believe those were the codes I was just going from memory on that. I do know it had the 86 code for sure though. I will get it all back hooked up tonight and report...

    94 4l80e limp mode

    I did some reading on other posts but never really found an answer. I have a 94 2500 with a newly rebuilt transmission, I put the tranny in about 8 months ago and have put about 4k miles on it so far. Everything was going just fine then they other day as I was driving down the road it went into...

    94 Chevy 2500 electrical issues

    Thanks for the replies..... we figured it out. Ended up being the ground wire on the back side of the head on the passenger side. I did take off and clean all of the grounds I could find and also added back that one body ground strap. Here’s where it started making sense for me. ABS module...

    94 Chevy 2500 electrical issues

    I plan to go back over everything this afternoon, initially looking I couldn't see any pinched wires or anything like that but I obviously done something while I had the transmission out. I really don't want to pay to have it fixed I just bought it for a farm truck and I've already spent alot on...

    94 Chevy 2500 electrical issues

    How bad can a faulty ground mess things up in a truck? Long story short everything worked fine, I pulled the tranny had it rebuilt put everything back together and now I have issues. I don't even know where to start, first thing I noticed is the brake lights quit working, blinkers worked running...

    4l80E differences???????

    Hey thanks for taking the time to reply I was hoping you’d see this. It seems you are the go to guy for this kind of information. So with that torque converter being a higher stall what does that mean? I understand that the original one was like 1600 - 1800 stall and this one is 2200 — 2400 I...

    4l80E differences???????

    Hate to be the guy to resurrect a 6 year old thread but hey it's 2020 and everything is out of order anyway so why not...... Will a 4l80e out of a 1998 work in a 1994? I have gathered from this thread that it "should" work?? I guess I am looking for a for sure answer. I know I will have to...
