Castrol Syntorq Replacement

[LarryB]

Seems to me the answer is in the temp gauge. Cooler is better no matter what conditions, load, time, label, or color it is. If energy put into the input shaft is lost it can only leave two ways. Torque out the tailshaft, or heat. Heat loss can be from viscosity loss or friction/pressure loss, Both bad, tailshaft torque good. Seems straight forward, no babble needed. Run the coolest running oil.

Where can I order Syntorq from?

Facts you say,you only are trying to post facts.....

FACT-No matter what brand of gear lube you use once it is established that the lube was not responsible for the failure and the power was, your on your own... I am my own warranty station... .

FACT-Dealers will not dance around the power enhancement and warranty issues,in their mind its cut and dried,if its altered its void... I am my own warranty station

(Oh by the way Don,dispute me on this-I do have the service bulletin that was handed out from Ma mopar to its service writers and mechanics,,See it was handed to me when we got into a heated discussion on how I wanted my truck repaired after the second KDP broke and they wanted to repair it to factory specs and since I was footing the bill,which I knew in the beginning,I wanted it done my way,,It lead to it being towed out and done at a local shop and done my way)

FACT-DC can not tell you what to use in any way as far as lube goes or they would have to provide it free of charge... .

FACT-Most every member is aware of the repercussions their actions will take and you need not keep reminding them,enough of the warranty white knight stuff,its tiring. .

You know ,I'd love to be the service writer at your favorite stealer when you try to convince them your motor has only small enhancements at 450??hp and it really did not cause the failure the lube did,,I'd still love to see the look on the local Castrol reps face as he gets to read your post about their lube backing the warranty on a modified truck. . You truly amaze me..... Andy

I have to say that I have never heard of a KDP causing damage on any engine more than once. You and the engine must certainly be the first to have this happen.

lets take a breather guys!!

this topic is old, it has been over numerous times now.



And once again with the personal attacks and bickering back and forth, THIS thread is going south quickly.



please try to stick to topics and not personal attacks about how others choose to use their trucks. even if you edit them right back out



just a few reminders:



2. Conduct;



2. 3. Post or transmit any material that is mean-spirited, abusive, obscene, hateful, fraudulent, threatening, vulgar harassing, or defamatory (the use of symbols or characters to mask profanity and expletives is prohibited and undermines the spirit of these guidelines);



5. Vendor Participation;



5. 1. The TDR Discussion Forums are not an appropriate forum for emotionally charged discussion between manufacturers, distributors, dealers, shops and/or users. These forums are intended to be technical resources for members interested in learning more about the proper care and maintenance of their trucks. All Vendors will refrain from making direct, emotionally charged, posts to and/or about competitors. All Vendor posts must be civil and technically oriented. If Vendors wish to compare products with competitors, use generic references (i. e. “oiled element air filter” as opposed to Amsoil, AFE and K&N).







Thanks Gang,

Well since you put it that way ,you forgot one Todd... ... ... ... .

"5. 3. Vendor participants must have their business name incorporated into their signature block. Vendors may include their business telephone number within their Profile so that it is available to other TDR website users"... .....

Since we all know in the past this was brought up and rules were again stated above, let us not forget it either... ... .

What about the Amsoil GL-4 gear oil? That wouldn't "attack" the soft metals and it's way cheaper the the Series 2000.



Oo.

 

[JStordahl]

Yeah Extreme: I've got the GL-4 Amsoil 80-90 in the NV4500 and it just shifts slicker than sn*t. I used the GL-4 because of the synchros as mentioned in this thread.

 

[JJW_ND]

Soft metals???

I have not seen every part of a NVG4500 but I recently had a Trans shop here in ND that does the fully splined main shaft show me the difference between the new 6sp syncros and the older 5sps. Their is a big differene. There parts area had every part to build a transmission from scratch. He pulled a few 6sp and 5sp syncros to show the difference. He specically said their is no BRASS in a 4500 like a lot of older transmission used to. The syncros looked like a composite material. He said a 4500 should shift great from the get go were as the 5600 (6sp) would get better with time because of the syncro design. Maybe there is brass but I did not get the impression their was.



Based on my experiece of one truck and how it was used I found it hard to believe you could get a 5sp in a dodge hot enough to hurt anything in a STOCK TRUCK! I define hot as it relates to GL5 problems of around 220 degrees. I have never seen 200 degrees in over 200K and my motor is turned up and most of my loads have been way beyond what Dodge rated the truck for. You have to have the power to stay in 5th to generate heat. If you have the power to stay in 5th, don't blame the transmission oil!



My original 5sp was R&R to repair 5sp damage after several dropped nuts at 150K of high horsepower, overloaded abuse using GL5 fluid only to find everything was in good enough shape for continued use. That transmission shifted allot better then the new 5sp I replaced it with.



I am just not buying this soft metal GL5 stuff.

Go for the "multi level" marketing oil just so you can save that A----l dealer wear and tear on his keyboard!



Seriously, Read the TDR register, couple quarters ago, Syntorque is proven but many can't handle the truth. Go for the SYNTORQUE!

"Never argue with success". Mines got over 170K with Syntorque and Delo in the Cummins, mostly towing 4 horses around the country. Uncle Jack had nearly 1/2 million miles on his '96... all towing for an RV manufacturer.



I do not sell any oil... . where do you find the truth, a salesman... NOT.

I believe that Amsoil is a great product and am using it in my engine. After changing my trans oil (dang 5th gear) and filling with amsoil and running 10,000 miles I can hear slight bearing rattle at idle with foot off clutch that goes away when pedel is depressed. This was not present before. I am goning back to Syntorq as its way cheaper than a trans. The bearing noise seems much more noticable when running freeway speeds for a while. Who knows if the oil is the problem but will find out soon.

 

[Alaskaskiff]

Every combination of oils and rebuilders will have problems to some degree. I just lost a Standard Transmission rebuild at 12,000 miles (only ran Castrol and was on second oil fill) when it went. I lost several teeth out of fifth gear. Looks like a manufacturing defect in the gear (rust deep down in one of the breaks), but hard to tell for sure. This transmission has only towed 350 miles (GCVW of 13,700).



BTW Standard gave me a fair offer for fixing it, but it would take too long since I am on the road and moving. Enterprise is closer and faster.



At this point the NVG4500 has me jumpy since I am depending on it. Going to try Amsoil series 2000 this time. Will it make a difference? I don't know, but I feel like it is time for a change.

 

[Joseph Donnelly]

Considering your own comment, the failure does not seem oil related. A defective gear. . .



The synchro rings have fiber liners like automatic clutches. They are a dark colored brass/bronze/phosphor bronze or some such soft metal. There HAS to be soft metal somewhere--you wouldn't run hard synchro rings on hard synchro teeth on the gears. The shift sleeves are ferrous, the gears are ferrous, the rings are not.

 

[Alaskaskiff]

Joe,



I hear you. However, I am going to try another route, "just in case. "



I ran series 2000 in my first transmission (not the current failure) for a while and really liked it. The transmission had an oil control problem (predating Amsoil) which did get worse over time and eventually cost a clutch so I went with the recently failed full spline unit.

No, the oil is not the problem, it would have done the same thing with the factory fill. No doubt it was on its way out before you fixed 5th and switched.

You switched too late! Amsoil cannot replace lost metal!
