I'm nearly finished with the swap, but it seems the transmission doesn't get into first. I have a PTC 3000 stall TC in a stock 4L60E, and my truck's a dog from the start. Look at my sig to see details on truck. Here are the codes I'm getting:


P0706 - Trans Range Switch Performance (Old) (History) (Immature)
P0740 - TCC Enable Solenoid Circuit Electrical (SES) (Old) (History) (Current) (Immature)
P0753 - 1-2 Shift Solenoid Circuit Electrical (Old) (Current) (Immature)
P0758 - 2-3 Shift Solenoid Circuit Electrical (SES) (Old) (History) (Current) (Immature)
P0785 - 3-2 Shift Solenoid Circuit Electrical (SES) (Old) (History) (Current) (Immature)
P1860 - TCC PWM Solenoid Circuit Electrical (SES) (Old) (History) (Current) (Immature)

I've got access to HP Tuners, and tried to drive it for the first time. With no exhaust, I expected a lot of power loss & lots of noise, but it felt as if the truck wouldn't go past 10mph. Any help would be greatly appreciated. Thx!

Did you forget to plug the trans harness in? It sounds like it due to the fact that all the codes you listed are all inturnal electronic sensors and switches. As far as the performance, your truck was starting out in third gear.

If you have the case connector plugged in, you need to verify if you have power down at the trans from the computer.

 

Got a reply from another forum suggesting circuit 239 or 839 might not be powered to the trans. Since this is all custom wiring, I did miss one. I'll have to try tomorrow, after work. I don't have the data cable to scan (have to borrow from a friend).

Oh yea... yes the main connector on the trans is plugged in.

 

Sorry man I had to ask!! I did also edit my last post asking about power to the trans. Sounds like your headed in the right direction. Good luck, Vince.

 

see Ron, I told you it was somewhere in the harness. You set every code the transmission has to offer. And now you know that it wasn't in second gear like you said it felt like, that was third (IBbigblackbeastgonnabescary)

Now get a powersteering hose that'll hold

 

Tell ya what Ron, for $50 Ill let you come dump it at the shop then you can just walk away from your headache. This is a buddy deal, I usually charge $150 to take someone elses headache.

 

Hey, dangit! I believed ya. That's the logical thing. I poked around on forums to get more specific. Luckily someone else seen this exact thing before, and now I have a more specific direction.

As for you... you'll probably get a headache trying to figure out how black beat white (and I ain't referring to my skin, nor rock paper scissors). Maybe that's why you hadn't told me how much, and when you'd be able to help me with the e-fans, huh??? You'll have the first chance to line 'em up when it's all said and done. I'll make the official call-out when it's time.

 

Problem solved. Circuit 1020 had no power. Trans shifts great now.
