60F this morning, 64mph per gps.. [ATTACH]5680[/ATTACH] (the lower right boost gauge is actually my fuel pressure gauge, and the red knobbed potentiometer is a temp test for the TPS/trans issue I'm chasing) Sent from my SPH-L710 using Tapatalk 2

It's hell gettin' old, ain't it? - - - Updated - - - So I got a chance to look into this, this evening, as well.. The harness plug has 5 wires, 6 wires; two are in the same pin. Unplugged the switch, and it has 4 pins. testing the harness, side. I found that 4 of the 5 wires function as intended, as does the switch. The one wire from the PCM that trips the OD light on/off is at constant ground, but it shouldn't be. That's why the light stays on. Also, wire positions 4 & 5 were backwards in the plug, so I swapped those pins around, but it still keeps the light on the switch.

I've got a way of doing that LOL I have not, it's dark now, so it'll have to wait. what, listening to Tom? heheh Tom spent a good hour on the horn with me discussing this stupid transmission and its nine billion gazzillion issues.. He's a great sound-board

Yeah my truck at 65 is about 4-5psi and 21-2200rpm with egts in the 650-700F range.Sent from my SPH-L710 using Tapatalk 2

So I got the 1k resistor in. Now no OD at all. And trans temp light is on.. WTF. LolSent from my SPH-L710 using Tapatalk 2

Ok so I found out why the codes with the trans relay in. No 12v on pin 86 (gen) wire. So ive temporarily patched 12v IGN to pin 86 until I can find the failure. Sent from my SPH-L710 using Tapatalk 2

In an effort to determine if any of the 'built trans' stuff was legit from previous owner, I decided to pull the trans inspection cover and look at the TC to see if it was a billet unit. Checking it out, it was painted silver with no markings. I know the OE ones are not painted (none that I've seen, anyway). I scuffed a little paint off of the drum and sure enough, it's machined billet. I was also told by prev. owner that it was a Suncoast TC and VB. I called Suncoast today, and he said 99% sure it's a triple. I explained my situation and diagnostics to him, and his end result was "Without some technical results, I'd have to say either the TC is failing, and or the transmission internals are in need of repair."Duh.So, for $450 + parts and round-trip shipping, they can check out my TC after I ship it to them. m'kay..

2778 @ 80psi dualIll see if I can scale the truck this afternoon. Sent from my SPH-L710 using Tapatalk 2

Looks good! (...and chunky!)

no worries. I hope you find it! - - - Updated - - - Sam, I just looked in the 2001 FSM, and it says, also, Front bumper, right support for JC3. The horn grounds go to JC3, as well as the ABS controller, and the RIGHT park/turn signal. http://forum.mopar1973man.com/attachment.php?attachmentid=5673&d=1370350731

Tom, I really appreciate your suggestions. There's not a lot I haven't done (within my means) in the past 10-11 months of jacking with this trans.. I didn't get a chance to test the relay pinouts today. I'll try to take my DVM to work with me tomorrow, and check some of the connections at lunchtime.

I called goerend a few weeks ago. Want me to buy a valve body or take is for trans repair. Sent from my SPH-L710 using Tapatalk 2 - - - Updated - - - So, in looking at the wiring diagrams, the trans control relay is as follows: 30: From Fuse #9 (20A) in PDC, 12V constant 85: PCM C2/B30 - Trans Relay Control 86: 12V Alternator wire (I assume it gets 12V when engine is running only) 87: To Trans 8 pin plug, pin #1 (12V feed to trans) So with the jumper between 30 & 87, no codes thrown, but trans shifts into OD immediately after the 2-3 shift. with the jumper removed and the relay in place, the PCM immediately goes into LIMP mode as soon as a gear is selected. Several different codes are thrown. It did the same thing with the old PCM, as well. - - - Updated - - - I did get a chance, this evening, to drop the transmission inspection cover. I wanted to get at least some verification of whether or not the torque converter was stock style or if it was a performance style.. The TC was painted gray. Turning the trans by hand, I found no markings anywhere on it. At least it was clean and dry I did find a portion of the TC that had paint scraped off (possibly during manufacturing or packaging process) and behind the paint is a very shiny, almost machine finished body. That tells me that it's most likely a billet TC. I'll most likely order another BW HD governor solenoid, but probably get the extreme duty one. I don't want to throw a lot of money at this trans issue, as I'm still on the fence of whether I save for a 5 speed swap, or save for a total trans rebuild.. :banghead:

Oh ok. Sent from my SPH-L710 using Tapatalk 2

did you see my post above? 8 pin connector using 7 of the slots?

Ok... premature. . It works great, but after 40mi of a 50mi roadtrip, it kicked out of OD @ 60mph. Takes a key cycle to fix it, but it will do it again shortly afterward. The trip to destination only did it once. Trip home did it 3 times and I finally hooked it back into the tps. I need to also find out why the trans relay in place will instantly go into limp mode.

Works like a champ! OD engages about 41 and kicks out about 32mph. This is scaleable too;)Sent from my SPH-L710 using Tapatalk 2

I just picked up the parts today. Sent from my SPH-L710 using Tapatalk 2 - - - Updated - - - So I had a delivery today, towing the 20ft enclosed trailer. Empty weight is about 3100. Had about 1200lb of gear in it, so roughly 44-4500lb. The property had a fairly steep grade, maybe 6%, and about 500ft of gravel/dirt lane, and very slow going, as there are some ruts and such. I came out of there in 2HI, low gear selected, trans temp gauge ~150*F. By the time I got to the top (about 1 minute), trans temp was ~200F, and the entire crawl out felt "slippy" with the trans, which would account for the temp climb. Later in the evening, I returned and picked up the unit, adding about 700lb to the trailer weight. I tried 2LO this time, low gear selected, same result. I'm gonna end up pulling the remaining hair out of my head, due to this transmission..

that distance in my truck would cost ~ $115

Seriously, YOU said this... in public?? Sent from my SPH-L710 using Tapatalk 2

So if my axles are: Fr: 4850 Rr: 7500 Tire: 3642 @ 80psi Fr: 4850 / 2=2425 / 3642 = .67 x 80 = 53.3 (55psi) Rr: 7500 / 4=1850 / 3642 = .51 x 80 = 41.2 (40-45psi) IS that right? That's using the door sticker's axle weight and BFG tire numbers.

sounds to me like something is amiss.. The HX should definitely drop EGTs and drive pressure, with a slight decrease in spool-up time.Did you buy a used HX35 or an ebay unit?

So how about math for my dually? LolSent from my SPH-L710 using Tapatalk 2
