Hey guys I got some codes from my transmission, your right it sounds like a electrical problem. These are the codes that are active...............

PO740- TCC circuit Malfunction..
PO753- Shift solenoid A, Electrical..
PO758- Shift solenoid B, Electrical..
PO785- Shift/Timing solenoid Malfunction..

Where should I go from here?....Please Help....

 

Did you have the main harness connector disconnected? If so make sure that it fully snapped together. This is the large gray connector that is located on the passenger side of the vehicle on the transmission.

 

No, never touched the main harness....I'm 99% sure that all the solenoids are pluged in. But I had to of missed somthing because my trans is not acting right...What could this problem be.?...

 

Did you have the ignition on at any point while the connectors were disconnected? Try to clear the codes and see if they come back. If so is it all of them? Also you might want to check, if you did have the ignition on while doing the kit, that you did not pop a fuse for the transmission electronics's. Just a thought. It would be nice if that is all it is without having to drop the pan again.

 

No, I never had the Ignition on during the install of the HD-2. I do have a diablo sport hand held that I checked the codes with and made sure it was set back to stock setting's for the trans. I'm starting to think I might have a pinch wire or broken wire in the main harness...have you ever see this happen before Vince?...

 

I was just thinking the same thing. Did you install the 1-2 accumulator housing after the valve body was up? I'm thinking that a couple of wires got pinched there.

 

I insalled the accumulator housing before the valve body, but there was two wires in the harness that was in the way at the rear of the valve body and I was carefull aroud them, not sure what it was but I teated it with care.

 

sonds to me that you have created a cross leak amongst other problems if you installed the acum before the VB then the gasket probably wasnt lined up and with 1st locking the tranny down this kinda supports the theory

 

I think my best bet is to drop the pan and inspect the harness, make sure everything is connected and look for damage with the harness. If I find anything repair as needed....Thanks for all the help Vince................

 

What are you talking about Perforabuilt?...I'm lost now?...
