#1995 4l60e transmission code

After flashing in the 4L80E calibration it ran as it should. I'm starting to regret trying this swap, but I know it will be worth it if I can ever get this running right.I used an 02 4L80E with my 02 PCM in my Express but did the same as you with the wiring.

#1995 4l60e transmission how to

bin files for that setup or even start researching how to tune that on my own. However, I also have an Edelbrock MPFI setup waiting to go on after the trans is sorted out, and I'm not sure how I would find. For now, this truck just has a Whipple supercharger making very low boost, the trans swap is the most complicated part of the setup where tuning is concerned right now. The reason I ask, is that this build will be continuing and requiring more custom tuning, and I'm not sure how I could get the skills or knowledge to do it correctly. How long did it take you guys to learn how to burn and custom tune, and how much time did you have to pour into it?

Thanks for the link! That's great! Unfortunately, I don't have any chip burning hardware, but if I can't get the tuner to fix this, then I'll definitely be going that route. Just frustrating when it takes a week or more in turnaround time to get a fixed tune. Obviously something with the tune is wrong. I need to take it apart and see if the chip is backwards inside the Memcal. know that the Memcal unit is not backwards in the ECM. Did the shop say whether they had tested it? The BJDR bin on this page should work for you. If it has that many errors, it might be a bad chip (or installed backwards?). I'm starting to regret trying this swap, but I know it will be worth it if I can ever get this running right. I'm fairly certain it's either the ECM or the tune, because literally every DTC for the transmission was thrown, including some like 'Solenoid B Stuck ON' and 'Solenoid B Stuck OFF'. Do you think I should try using DM35xOD, which is for the 4L60e? I used TTS Datamaster DM35x31, which is listed for the 94-95 5.7L trucks with a 4L80e. If you guys have any ideas or suggestions, I'm all ears. The two wires from E10 and E2 in the ECM from the 4L60e diagram were moved to ECM pins F2 and F3 and were removed from the transmission plug (not used), and were spliced into the new Input Speed Sensor. The Brown wire from ECM pin E11 was moved from pin 'U' on the 4L60e wiring diagram, and put to pin 'S' on the 4L80e wiring diagram. I rewired the transmission according to these diagrams, sent to me by the tuning garage.Īccording to the above diagrams, 3 wires were moved.

I checked the DTC codes with TTS Datamaster, and almost every code for the transmission was showing. I had it swapped in, changed the wiring around, and had a custom chip burned by a reputable OBD1 Tuning garage. If you need specifics on what was put into it, I can get those.

It should basically act like the newer 94+ 4L80e's now. I had that trans rebuilt, so it doesn't have the Bosch Force Motors. It's a 91-93 model, but it had the electronics updated somewhere along the way, so it has the newer plug. Four months ago, the trans lost third gear, so I decided to swap in a 4L80e. I have a 1995 Yukon with a 5.7L and a 4L60e. Be warned, I haven't really ventured into this on my own yet, but I look forward to learning. I heard this is the place to learn about computer tuning for the old TBI systems.
