Transmission and ABS
system issues... Looking for some insight
Looking for some help narrowing down some issues I have been having with my 04, any insight and knowledge will be greatly appreciated.
A little while back I started having issues with my truck, the ABS
light would come on periodically and go away. I also started noticing that the truck would take 3 seconds to shift into reverse. It was that bad at first but then the truck developed a small 3-5 shift flare and the tow/haul light would come on. It got worse over time so I parked the truck because I didn't want to do any more damage then what might already have been done and I wanted to research some things so I could fix it.
During the time it was parked I kept the batteries charged and would start the truck periodically and let it run. I read about the shift flare learned about a potential issue with a direct drive solenoid and the rear speed sensor. I tried pulling codes with my SGII and my Torque app but got nothing obviously since neither of them will pull transmission or ABS
codes. I am working on getting an AE
so I can get more information than what my gauges, SGII, and Torque app can show me.
Today I finally drove the truck to see what is going on. Before I drove it I took the transmission harness plug off of the side of the trans and cleaned it with electric contac cleaner to see if that would help anything. During the drive it was doing the same thing it did before as far as the 3-5 flare, but started acting even worse when I came to stop and tried to drive forward. The truck acted like it didn't want to move much at all, the rpms would go up and the truck would not much like it should, then it held the rpms up around 3k then shift funky. Once that started the tow/haul started flashing constantly, the ABS
light was still on constantly as well. I got to a place where I could turned the truck off then restart it. When I restarted it the tow/haul light went away but the ABS
light was still on. I started to head back to the house and the truck was driving better then it all happened again. I was able to limp it to Auto Zone and they happened to have a scanner that would pull transmission and ABS
codes. They pulled three codes, C1230 - ABS
rear speed sensor, B1676 - battery voltage out of range, and C1185 - ABS
power relay output circuit failure. They had a speed sensor in stock so I picked it up and swapped it out when I got home. The ABS
light is now gone, but when I took the truck for a test drive it started acting the same and the tow/haul light started flashing again. Another thing that is odd is when I pulled up to Auto Zone I could hear a weird sound on the driver side of the truck that sounded like a loud electrical buzzing or ticking sound. After my test drive I parked the truck and left it running while I looked for the sound and it definitely sounds like it is coming from somewhere on the driver side, not exactly sure where though.
I was already preparing myself to replace the direct drive solenoid to see if that fixed my issue and have a buddy of mine that has a trans core that I can get rebuilt but the ABS
issues are throwing me for a loop. Could the ABS
issues be the cause of my trans issues or do I have a combination of both? I hate just throwing parts at things, I've learnd that lesson in the past, and I need to get the truck fixed as soon as possible.
From what I have researched the codes I have are all ABS
related but I am trying to figure out if they are also related to my transmission issues. If anyone has any thoughts or experience with any of this please chime in.
Thank you in advance!!
