Ok, I know this has been hashed over untill its blue BUT, has anyone had any 6 spd transmission probs after using Redline MTL that DC denied warrenty coverage on because of the oil. My truck is shifting 'different' than it used to and I figgured I would change the tansmission oil. At 50K I figure it is due. I can not justify spendng the $22 per qt that DC wants when a probabally much better oil can be had for $8 qt. Queston is, If this is signs of early syncronizer wear I don't want to void the warrenty to save $70, Anyone had any issues?

I did call Redline, they said their part numbers, along with some others, cross over to the DC numbers. Does this mean its ok by DC.

Thanks.

Oh yea, I have searced the archives, nothing defenative (sp?) there.

 

I don't think anyone really knows whether a substitute fluid might harm the transmission or whether the dealer would give you any problem with the warranty (would probably depend on the dealer) but IMO the safest thing to do is to stay with something that has the right spec number on the bottle vs. some vendor's opinion that their product is 'compatible' or 'recommended'. However if Redline can say that MTL specifically meets the numbered spec in your vehicle owner's manual then you should be OK with that product.

Penzoil Synchomesh fluid is an alternative to the dealer stuff that meets all of the requirements and exactly matches the lube spec number in the manual so you can avoid any warranty concerns... and it is available at a much more reasonable price, similar to MTL, maybe even lower. Some have reported finding the Penzoil product at Autozone. Here is a spec sheet: http://www.pzlqs.com/Tech/Pdsheet/Do...omeshFluid.PDF

 

My question is "how would the dealer even know?". I've worked at a DC dealership for over 7 years and I've never seen an oil sample be sent out to be tested. The only warranty issue you could have would be service intervals. If the manual specifies that the tranny oil be changed at 30k and you can't prove that you've done that, they might refuse the claim. I don't work at the dealership anymore but that has been my experiences from that side of the fence.

i don't know if it will void the warranty but, mine does shift better since i changed to redline mtl.when you do change your trans fluid take the pto cover off, there is a magnet in the bottom of the trans, you can see how much metal,etc. is in there.if it shifts better one would think it has to be better.?

 

by all means , change to red line...it is a superior lube & it will not void your warranty

 

Duane, thats the very same question I have.....I need to do a change pretty soon too. I know a 25 year tranny guy on another site and he has said NO to the Redline....and to only use the recommended lube.

 

OK guys, here's the deal:

Redline MTL does NOT meet the mopar spec (MS-9224). If pushed by the dealer after a tranny failure, they COULD void your warranty. See my rant here:http://tdr1.com/forums/showthread.ph...light=warranty

But you need to consider the other side of the coin. At ATS transmission, I was told that almost EVERY SINGLE failure they had seen of the NV5600 had to do with two things-- inadequate lube (the OEM fill!), and not changing it often enough.

I've NEVER heard of a 5600 failure on Redline MTL. You can't say it will never happen, but it's pretty rare. So rare, that it should govern your decision to use the MTL or not. There are hundreds of MTL users between this site and TDR, and you won't hear any of them speak badly of it at all (other than price).

I bought my truck new in '02. I switched to MTL after only 15K miles. The truck shifts many times better, and I'm glad I switched. I will run it in the trans as long as I own it. The improvement in cold weather shifting has to be experienced to be believed.

Moreover, I change the lube every 30K. It's cheap compared to a new trans.

Ask yourself this: what about AFTER the warranty? (remembering the DC spends a lot of time trying to get out of warranty claims, and it's you against their army of lawyers)

What happens after your 100K on the "spec" lube? You find yourself in the situation where your trans is more worn than it should have been because you used the "spec" lube instead of something better. Only now there's no warranty to cover you when it fails. What if MTL is the difference between going 120K on a trans and going 200K on a trans? That warranty is no good to you then!

If you plan on trading at less than 100K, then maybe you don't mind the downtime if a warranty repair comes.

I, however, am married to my truck, so I'm doing what I can to keep it from EVER going down to begin with-- warranty or not.

Ok,
Spoke to a dealer today, wont say where 'cause site could be monitered. He said he would NOT use factory oil at the price they wanted and kind of laughed at the idea of a lifetime fill on any type of lube. Also said he saw NO reason not to use a probabally much better oil. We also looked in his manuals, was nothing we could find on ONLY using Mopar oil in his books. Seems like a really good dealer, was not even where I bought the truck. Stated that he could see no reason DC would be able to void warrenty based on brand of oil used. Redline MTL is a API rated GL-4 oil, so should be safe. Gonna get it changed tonight At $8 a quart and only needing 5 qts I cant see how anyone could consider it too expensive, not considering the expensive peice of equipment it is going in.

Thanks everyone.

DuaneW.

EDIT:
anyone notice that NO one stocks that much MTL (5 qts) Jeggs just looked at me funny and I said its a truck, not a race car!

 

I ordered mine from these guys: http://www.pitstopusa.com . 9 quarts of gear oil, 3 of MTL, and 2 of MT90. Their price was the lowest I found, at $6.98/quart.

 

Sorry, Redline MTL does meet MS-9224 in that it exceeds that spec in every industry standard metric.

I hashed this out with New Venture over a year ago and posted the results on this forum. A summary:

(1) For purely corporate (read business) reasons, NVG chose to test the NV5600 transmission with a certain brand of lube. They then characterized that lube according to industry standard tests in a slightly revised spec, MS-9224. They did not test the transmission with any other lube.

(2) Industry standards are, by definition, standard. MS-9224 lubes are minimally-conformed to meet the needs of the NV5600 transmission through its warranty, and contain nothing that Redline MTL does not have. The only difference is that Redline MTL exceeds the MS-9224 spec in every industry category.

(3) NVG admitted that Redline MTL was a superior lube oil for the NV5600 over the MS-9224 spec lube that they used in their tests, and that it should work fine or better. However, they stated that they could not recommend it because they had not tested it in the transmission.

(4) The Muncie, Indiana, jobber to whom NVG sends its warranty-claim transmissions for rebuild stated that Redline MTL is a superior lube oil to MS-9224 spec lubes, and highly recommended it. He says he's never seen an NV5600 transmission in his facility that ran Redline MTL.

Further, the owner's manual for some 2002 Dodge CTDs state that MS-9224 or equivalent lube oil must be used in the NV5600 transmission. Mine does; my neighbor's does not.

None of this is going to save anyone from a warranty hassle if DC decideds to make a case out of it, however. It just means that if you want to challenge them and spend the money and time making a case out of it, you may have a better chance of winning.

 

I have heard that in the 6-speed it is better to use a mix of mtl and another redline oil (mt-90) that it works better in the six speeds. Im not sure why, but there are a couple of people on here with the mix, maybe they will chime in.

 

If your still concerned after all the above, there is an easier way to look at this situation - assuming Redline's customer service will tell you their MTL is right for your tranny.
As has been discussed previously and often, legally, dealer can only void waranty if he can prove the product you used caused the problem.
If he can do that, Redline's product liability insurance should kick in and cover your bill - since they recommended that product.

Justin makes an excellent point - high quality lubes from the beginning are the best insurance against post warranty problems.

Hassle? Yes IF you have a problem. But Redline's insurance does give you recourse!

We could argue over whether or not the MTL is "spec", but it doesn't matter. I'd run the MTL whether it was spec or not.

Redline Products rock

oK,
The Redline is in, very big difference in how the truck shifts . Not only does it shift better but the transmission seems quieter (sp?). Anyone with a six speed ever notice that if you sit at a red light with clutch in, put truck in neutral and let the clutch out, the momentary drag on the motor till transmission gets up to speed, this is virtually gone with the MTL. Also, the redline felt different than the original oil, smoother & slicker, not shure how to describe it. Granted there was 50K on the existing oil, but this is a lifetime oil, right?
Anyway, glad its changed. Not alot of stuff in the bottom of transmission but some thick grey goop and a little metal on the magent.
