1G Transmission stuck in limp mode

[90_AWD_Thunder]

Ok, just got DSMLink and installed that get ready to tune and found my trans is in limp mode.

When I hook up a scan tool to pull the codes to see if there is a problem there I cant get any communication to the TCU but I can link up with my ECU. Checked the fuse it is good (replaced it anyway just in case) now I am led to a broken/shorted wire or bad TCU.

I pulled the TCU and there is some corrosion around one of the capacitors leading me to believe that the TCU is junk (it actually looks like the cap leaked. So, I don't know where to go from here and I will ask if anyone has a good TCU as I can't find any place that can repair them.

Any help would be appreciated.

Have you asked Thomas at ECMTuning about repairing your TCU?
I don't know if he does but he is very knowledgeable and might know someone if he can't repair it.

I would just remove the TCU and get a shift box from Road Surge. From what I have seen in the pass it will cost more to have the TCU repaired then just getting the shift box

Yes I did check with ECMTuning and no he can't repair it. And I did think about the shift box but I want to have the option of full auto and manual where the shift box would only give me manual
