I recently had catastrophic failure due to a motor mount issue. I replaced the head gaskets on the engine, and I am having trouble getting the electrical grounds back in the right locations. I found a ground for the fuel injectors that prevented the engine from running. Now I am trying to locate the ground for the transmission. The symptom is a flashing TRAC light, and no transmission shifting. Any help would be more than appreciated.

 

this will not help you now, but maybe later as you repair things, lay them out in the order that they come off and you can more easily reassemble them. not just tear into them and then wonder how it all goes together
