0x00008D IKE: EGS signal line disturbed [solved]
3 Attachment(s)
I was reading some existing threads here that closely followed my symptoms as I was experiencing intermittent loss of 1-2-3 gears. This issue started after I was doing some spirited driving in manual mode and would come and go intermittently with a ignition power cycle.
Can't even drive in forwards. the Trans Fail caption is illuminated. I believe that the ZF trans clutches for 1/2/3 disengaged and the trans is locked in 4th gear When in D. And still has reverse in R. When the symptom appears, 1-2-3 has no drive torque. Not slipping per say, as there is no drive engagement. When shifting into Drive, I got neutral, and once throttle input engine speed goes passed the specified maximum engine speed without wheel movement, transmission failsafe mode is engaged which shifts immediately into 4 gear, I can see it when I select manual mode. Intermittently when cold started, I had 1,2,3 gear normal shifting without any issue. Over time intermittent became permanent loss of 1-2-3 gears. And before losing the first 3 gears intermittently I was experiencing intermittent signal loss from the gear select module where I could not select between drive and reverse after starting up. There would be no square selected around either PRND. I replaced the shift select module and this issue did not return. After replacing my fluid, filter and a new valve body, I went for a test drive, and had all the gears as normal. Once I started to boot on it I lost the 1-2-3 gears and speed failsafe mode engaged. After this event, I could not get the 1-2-3 gears back even after a cold start. The torque converter is strong and there's nothing showing an issue with brake on stall speed tests. You can see it on the video when I test reverse and drive mode. Early in the video you can see after selecting 1 the engine revs up and then transmission goes to failsafe and shifts to 4, it then went to 5 just because I selected that gear with the shifter. video https://photos.app.goo.gl/cgyfTHUPdrPhUMft5 I decided to order and install a new rebuilt valve body and perform a service. I used AMS automatic transmission signature series oil, and new replacement filter. Parts List: Valve body, rebuilt, revmax V5HP24D https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1 Filter, PA CARGO 114710 https://www.rockauto.com/en/moreinfo...=1411737&jsn=1 Transmission oil, AMS ATFPK https://www.amsoil.com/p/signature-s...ion-fluid-atf/ I was really disappointed in the quality of the RevMax valve body - there was a critical and obvious flaw on re-assembly the technicians and quality checking persons didn't notice see attached photo. Furthermore ordering the part from the revmax website did not work and I could not complete their stupid forms to make my order without getting an error, so I had to order the valve body from amazon. I didn't notice the flaw on the manual selector spool valve either until I was on the final assembly stages after I had bolted it on the transmission. The spool valve to select the gears was not installed correctly so it could not connect to the driven cable from the shifter. Things I have done that follow what others suggested here based on searching for symptoms. Issue with No box around the PNRD, failsafe. CHanged the gear select module with part https://www.ecstuning.com/b-genuine-...h/24107512755/ And this particular symptom has not returned. Removed and inspected transmission harness connector, there is no corrosion on any pins. Replaced the valve body, fluid, filter. relevant codes from ista-D 0x00003B EGS: Stall speed 0x00008D IKE: EGS signal line disturbed DME/DDE - 0xDC (220) DME: CAN timeout, electronic transmission management (EGS/AGS) DSC - 0x3A (58) DSC: No message from EGS control unit EGS - 0x4 (4) EGS: Pressure actuator EDS 4 - 0x1 (1) EGS: Pressure actuator EDS 1 - 0x12 (18) EGS: Solenoid valve 3 - 0x11 (17) EGS: Solenoid valve 2 - 0x10 (16) EGS: Solenoid valve 1 KOMBI - 0xFB (251) IKE: No CAN identification (EGS) - 0x8D (141) IKE: EGS signal line disturbed attachments; old valve body rebuilt valve body rebuilt valve body flaw i had to correct |
The error literally says there's a problem with the communication line. I would try to trace the loom top to bottom, start with the top side connector sounds like you checked there bottom side connector

i only get failsafe and these two codes after the transmission is well warmed up. doesn't seem like an electrical issue to me at this point. however im open to being wrong. |
I think you have symptom and cause backwards.
The odd behavior happens after the TCU loses track of what the transmission is doing and goes into failsafe. It is reporting that the control line is unstable (can be from noise on the line or a short somewhere etc. |

5HP24 no 1-2-3 no change after valve body replaced
The temp of the trans oil may be a coincidence. Hot electronic will fail just like you describe.
I missed if you have V8: if so look into your ebox cooling fan. Continuity unfortunately doesn't mean much on communication lines. Noise from other paralel lines etc cause problems I have read a few threads where the fix for similar headache was replacing the transmission wiring harness |

I would say that you have a broken or crack drum or a torn o-ring. The fluid pressure can be obtained when the fluid is cold and thick, but as the fluid warms up it loses its viscosity and can no longer maintain the fluid pressure due to the fluid leaking pass the crack drum or o-ring for the trans to operate correctly. A rebuild is in your future if you want to keep the X.

that last one is a good idea. Maybe you can determine a particular temp it happens. If you can cool the ebox (Ice Inna Ziploc) to keep it cooler and error doesn't happen, you can home in on the defect

I was able to open up my TCU to check for bad solder joints etc. I may have had to drill out rivets but was easy to do. I had signs of corrosion so I wanted to look inside and clean it.
