When the trucks transmission was rebuilt a Goerend triple disk torque convertor with a stall speed of 800RPM along with a billeted flex plate was installed. My line pressure at idle is 90PSI+ and the truck has an E-brake and is setup for towing a 5th wheel with a boat behind it so having that heavy duty convertor is a must.

Had the thought today of while the engine and transmission apart should I upgrade my single disc torque converter? Transmission has had pan off upgrades done and it was rebuilt a few years ago when it was rebuilt we were in a tight spot and all I could afford was a basic single disc billet. I dont beat on the truck hardly ever tow but the transmission has always felt like mud till the OD locked up. I would think a lower rpm stall would also be good but no clue how low is good. Any suggestions on brands? stall speed? Should I just run the billet single?

Thanks for the info I am still learning about my 2002 Cummins and this info and much more have helped me very much.

I hope they find what the problem is. Please let us know how it works out with this ECM repair shop so we can update the article "List of Verified and Reliable PCM/ECM Rebuilders" in the 24 Valve 2ed generation engine section.

After some thinking and talking to the wife, I’ve decided to send the ecm to someone else. I think the problem with ACS may be that their repair is based solely on the information I give them. The shop that fixed my turbos recommended a place they use out of Texas. I called them today and they test and check the entire unit. Just found out today my daughter can’t take drivers ed for a few more months so I’m gonna use the money we saved for that to get it done.

NAPA parts ive noticed that NAPA typically will upgrade there part line based on failure rates. I just reported a fuel filter that is not big enough to hold the lid. Look in 3rd Gen for my post about this.

Syco, you are going through a rough patch. It sucks when things fail in that manner. Yeah, you are going to have to make that call again and get it fixed to use your truck. I'm super curious about the test results and what happened.

This was so awesome. I ran into a older couple that shared photos of their son and all the stellar comments. Their son did the whole punk theme, mohawk hair, and in blue green color. Checked out of the store with our groceries to run into Stormy Rose, she is a young artist who started her own version of Goth makeup, very impressive artwork for even her age, super cool interaction.

Got my turbos reinstalled, unfortunately neither of the drain kits worked so there’s $200 down the drain. I did manage to get a nice fat 7/8” drain on the big one with parts I had purchased last year but wasn’t sure would work. I’ve gone through all the grounds and the harness and found nothing wrong. I guess I’ll call ACS on Monday and see if they want to try again with my ecm, otherwise it will cost a lot more to have someone else try and fix it.

The Napa in town just shut down a year ago. The orileys is pretty solid guys but their parts are just terrible this was actually the in house brand and it only lasted 2 years under warranty but that dont help when your on the side of the road lol.

Do yourself a favor DO NOT buy a Cummins water pump. Sadly, there are too many people who think Cummins is the best supplier, but actually, they are not updating part design for improvement, but finding a cheaper way to produce the product and charge you Cummins prices. I've dealt with NAPA parts for over 20 years with a low failure rate vs Cummins water pumps and thermostats.

Sad to think a 68$ water pump is what killed this mighty cummins.

Yeah that's not good. I'm going to say your right on. Getting the truck hot most likely got that head to curl some and just heat and pressure.

I am currently working on the website Terms of Use. We are revising each Module to make it more user friendly without the boring technical policy munbo-jumbo stuff.😏 It would be wise and advantageous for everyone to be well-informed; especially pay close attention to any new instructions or helpful guidance to best utilize this website. Stay Informed & Stay Tuned folks!😃

That head curl makes sense I took my broken head stud into work and had one of the material engineers look at it and what he had to say was that it was brittle fracture. His suspicion was that it was over hardened he also pointed out that it broke on the first thread on the bottom so that might have been a stress riser for it. That part of the head is the hottest section right next to the turbo is. I have my turbo and exaust header heavily insulated with rockwoll. My water pump went out last week and the truck got to 240° ( immediately turned the heater on and slowed down and it quickly droped back to 195. I think this event is when it broke. As much as I hate to say it I dont think im going to buy exotic head studs again I think the temper was bad coupled with some extraneous circumstances on my end but I still dont think it should have failed. Especially since the highest boost my truck has seen for the last 3 weeks was 12psi.

Freaking awesome! I've been watching you build that truck for YEARS! I'm dying to see it completed. So freaking close...!!!!

I'm set for 18 to 19 PSI lift pump pressure on Beast for over 400k miles no problems. The VP44 shuts off its most likely the PSG unit died on top of the VP44. Yes it is possible to have a injection pump that has ZERO codes but be brain dead and will not start. Don't let thart little module blow you away. It only controls timing (advancement or retard) then the fuel pin to pull it out to start the enginee and control the fuel amount. There is a bit of diagnostic code in there to produce error codes. There is only the timing solenoid valve to move the timing. Then the solenoid to control the fuel pin.

Basically when you get 300k miles on your Cummins engine typically they develope a condition called head curl. The ends of the head start to lift. This is why the head studs. Now about 300k miles you notice oil usage and that is caused by valve guides allow the valves to wobble which in turn wears the valve stem seals. Drive pressure gauge really doesn't need to be in the cab per se if you can design and test the first time drive pressures shouldn't really change unless other things change. (injectors, tuning, etc). I stayed down around 500 HP for a few reasons. One not willing to give up my exhaust brake yet. Smaller turbos spool faster than larger turbos. Remember the lighter the rotational mass (turbo wheel, tires, driveline, flywheel, Etc.) ther faster it will accelerate. To this day I hunt for oversize tire truck with a lift kit and whip them in a street race because of all the rotational mass. Just food for thought.

I do think I will convert 1 of my boost gages to monitor drive pressure. By doing the guides and seals are you referring to upgrading the valves and seals or just redoing them back to oem spec?

Well there is a reason a new injector pump comes with a new over pressure valve. which I believe opens at 14psi... so in MY opinion maybe turn down your lift pump a bit... I have mine set to 15 or 16 psi. Not that I think this would affect the condition you described. But I have heard that 18+ makes for a hard start some times.

Sadly I have nothing to "work" it with... it is back to daily driver status... I may hook onto the trailer and go pickup some firewood but even that isn't "working" it like I KNOW the truck likes. :) and the NOT WET status inside and down stream from the turbo is what most perplexed me... I was expecting "wet" as well.

Body now AT sandblaster.....but Tony (painter) is out of town for 2 weeks on a visit to family. Color should be close to this picture of my friends 52.

Im dying to see the paint job. Im going to be jealous seeing that pretty modified truck. Going to be a sight. 😎
