Driveshaft fab'd & looks nice. One Step forward. Ran into some transmission issues.

Getting the following codes:

P0122 - Throttle Position (TP) Sensor Circuit Low Voltage (History) (Immature)
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)

HELP!!!!!!

 

Problem solved... The main lead to the trans solenoids did not get power from the engine harness connector. On to the next task... resolving overheating issues.

 

I had a bit of an overheating problem with my new 383 so I got a radiator out of a diesel with Efans.....Works like a charm

Hmmm... it's strange. I've got the smaller LS radiator. I was under the impression that these came with the 4.8/5.3 motors. If this is true, what's up with this? I've got to hard-wire my efans to get them work. One of the two motors draws much more current than the other, thus blowing 20amp fuses almost instantly. I'll look at this tomorrow. Without knowing the specs on the motor, I'll be playing trial and error. Fingers are crossed.

 

Put a clutch fan on it just to make sure that is your problem. I got one Ill bring you this evening if I think about it.

 

When you bringing it? Guess I should've kept mine until I actually finished the project. Oh well... holla when ya think about it.

 

Ill bring it today later call me

 

No need... Fixed cooling issue. Pulled vent tube off radiator, and let about a pint of coolant run out. Clamped that back on, and started the truck. Ran it for a couple minutes, and noticed the reservoir bottle was getting low. Filled up with 50/50 liquid, and ran for about 5 mins with cap off. Coolant level in bottle settled. Drove truck around, and temp never reached the 210 mark (with 1 of 2 fans working).

Got exhaust done on yesterday. What ya'll think?














Tried to upload a clip, but it kept getting corrupt. Oh well...

 

Here's the clips I promised:

Idling under carport

In-cab cruisin' decibels

Not bad at all. It's nice is cruisin' speeds, and makes itself known at WOT. Caught this guy's attention walking down Millervile. As I pass him, he stops, and looks back at the truck like "what da hell".

 

Overheating... but, only detected on driver-side head (stock sensor/sender location). I've got an Autometer temp sensor on the passenger side, and it reads normal (190* - 200*). The stock sender sends a signal back to the PCM stating that it's reaching 270*, causing the truck to go in Overtemp Protection Mode. The t-stat & sender were replaced. I'm running e-fans (dual, but only pass-side is working).

Before I put the truck on the street, I was running it without a filter (in my driveway). I'm wondering if something got in the intake, but doesn't seem like it b/c the truck runs great @ WOT & cruisin. Thing is, I can get about 4 - 5 miles, and the temperature surpasses 250*, and shortly thereafter, it'll it the limit. I haven't been driving it far b/c of that. Wouldn't think the radiator's clogged b/c coolant flows out the radiator (top, on DS) when @ op temp.

I'll try to remove the rubber tube from the DS head to see if coolant flows thru that tube (hopefully it's not clogged). Other than that, I've exhausted what I can think of, right off.

Any ideas?
