Newby--'99, 6sp transmission fluid problem????

[Archive]

I was preparing to change the fluid in my '99 6 speed transmission and noticed a label on the side of the transmission stating Texaco 1874 must be used or warranty will be null and void. Anyone else seen this or have knowledge of same? Let me know,I'm new at the diesel game.

There are probably a number of different oil brands that would work. Myself,I would stick with the manufacturers recommended oil.

------------------
2001 HO 6spd,Quad cab,LWB,4x4,Flame Red,all options except for leather,Westin Brushguard/Push bar,Painless wiring,Radio Shack CB( so what it works},my own designed CB mount,Smittybuilt nerf bars,NW Custom rocker covers(more to come)

Aha! A Newbie!
That is an illegal scare tactic. Federal law forbids them to do that. In the owners manual, it will say "meet specifacations blah blah, we recommend blah blah"

We have went over this with the 5 speeeds.
Try Amsoil Series 3000 5W-30 engine oil. It blows away the 1874. Amsoil backs it up with a warranty.
Call their tech department if you wish.
I am sure there is other oil out there that would work, but I am not familiar with them.

Sorry newby, It's not illegal for them to do that. If you check your owners manual it states that the fluid is "lifetime". That means that you are suppose to not ever have to change it. I don't agree with that, but that is what DC states. If it was a fluid that was suppose to be changed, then they by federal law could not state that you had to use a fluid you can only purchase through Chrysler or they would have to give it to you for free. Since you are not suppose to change it, if you decide to, then it is up to you to replace it with the same fluid that is in it already. That is if you want to keep your warranty!!!!

Yes, and when your transmission blows from their lifetime fill they will say,
"I GUESS THAT WAS YOUR LIFETIME!!!!"

The burden of proof is on them, they can not Just say," Oh, you did such and such, you are void. "
It is just a sly trick to make money off the Nervous Nellies!

While I am LESS THAN IMPRESSED BY THE LACK OF TESTING/CERTIFYING of other manufacturers...
(ie Texaco makes it and carries the certification... and THEY (whomever they are) are not testing other oils)

To the extent of my knowledge, Amsoil is one of the MANY excluded by this lack of testing... and NOT carrying the certifcation... just like all the other oil firms getting hosed on this deal.

Day's end, your transmission and your call.

<fontcolor=blue>BE CAREFUL about using "BETTER" oils... They can effect the way the syncros work as well as other possible draw backs... Some SUPER oils and additives actually sacrifice the surface area with their so called improved sheer strength. .

Changing the fluid is a good Idea and there is a Manual trans filter add on. . But I would stay with a Oil or Lube that matches the recommended fluid. .

Kwikurt,
Do you have any proof or facts to back that statement up?

This topic has been hashed over in the past, and I related an experience I had with my Pontiac Grand Am. Specifies the same oil. At the first change the dealer told me to use a 5-30 engine oil. 20 miles later I drained that out and put in the expensive stuff. Two points. The dealer was wrong (does that surprise anyone?) and at least on the GM application there is definitely something in the recommended oil that is required by the syncros. I could hardly shift the thing with the 5-30. Put whatever you want in, but I see no reason not to use the Texaco product. IMHO, Texaco makes fine products and I have never had a problem using their stuff. The Grand Am has used Texaco Havoline 10-30 motor oil exclusively for 207,000 miles, uses about a quart every 1000 miles, but no knocks and still runs strong. Not bad life out of a iron block aluminum head gasser!

Hiya Jimmie, I have a 99 6 speed and I just changed the transmission oil this past weekend. I bought the expensive Mopar oil from the dealer. The reason for this is that I have the extended warranty and I want to cover my a$$ if the transmission blows up then DC can't say I used the wrong oil. The truck has 57,000 miles on it and now it seems to shift a little easier. I also changed the rear oil, I used a GL-5 gear oil with 1 bottle of friction modifier. I bought the modifier at the dealer and it was a Ferd product. So far my Dodge has not gone into rejection mode over it.

Texaco is the one making this stuff.

I was able to get 1874, texaco's 5 gallon bucket of MTX (stf) for less than my dealership wanted for FIVE QUARTS!

The Eaton/Fuller PTO Filter kit suggests changing the filter element every 25K for on road service, so I figure I'm covered on the oil equation for a long time.

MGM This information is from several different sources... The Oil for the manual transmission is important because of the way Your syncros work. Much like the Auto trans fluid back in the Type "F" trans fluid days. autotrans fluid was very similar other than a friction modifier built into the fluid for the correct slippage to occur with the clutches . So what I am Suggesting is if your transmission has a #4 Fluid requirement It is not always a smart Idea to believe that a #5 Fluid is better.

As for additives. . Some of the additives that are for sell in the market place actually give up some of the metal wear surface to produce their "SUPER" LOAD carrying claims...

After seeing your signature I want you to know I plan on Using Amsoil Products ( especially the Bypass filter setup) on my dodge. But will be sure that the specs and performance qualitys are the correct one for my Trans as well as my Limited slip diff. .

As to Proof or facts... If you need more information... Stay with studies from sources that do not sell any of the products in question... I have Been in Aviation Fuel and Quality control for 17 years with peoples lifes in my hands I take it very seriously. .

One such good information article on this subject you can find in a past issue of TDR magazine... I think it dealt with FUEL PROPERTIES as well as lubricants... . issue 24 or later ( I'm no sure which one as give mine to other Cummins owners)I hope this information is helpful...

Feel free to E mail me and I can come up with more printed independent studies and tests as well as field tests from trucking, Railroad and Aviation Fleets.

Thanks Kurt,

I'll be e-mailing you for more info. Always on the look out for facts.

It just seems since I bought this dang Cummins I've been battling "hear say"

You know, Ford owns Cummins, everything will void your warranty, Al Gore does not want your guns, etc.

I've had Amsoil series 3000 5w30 eng. oil in my 00 6spd for 50,000 mi. now. Its smooth shifting and no problems, and I tow 20,000# to 27,000# GCVW all the time. My dealer installed the Amsoil, at my request, when they replaced my original transmission at 29,000 mi. Brg. in reverse gear went out.

MGM... here are some for you to spread #ad

You can't get a PowerChoke in a DoDge BUT You can Get a Cummins in a Ford!
(Ford 550, 650,750 HD trucks!)


DC now owns 100% of Detroit Deisel (Allision)
AutoTrend magazine

According to the US goverment

The Powerchokes expected emissions Lifetime is around 130,000 or 170,000 miles. .

The ISB 5. 9 Cummins expected emissions Lifetime has just been increased from 300,000 to 400,000 miles. . #ad
#ad
#ad


And anytime the Phford Psd owners talk about how long their engines last just pick up the local paper and compare used Dodge/Cummins to Ford/Navistar trucks. . and point out the ratio of REBUILT ENGINES in the trucks... You will be lucky to see a truck that has had to have a Cummins rebuilt!

Oil Man,
I know you tire of rehashing old issues, but, your latest thoughts would be welcome here. Last time we spoke, you mentioned LE, or Mobil Delvac 1 or Amsoil if looking for a synthetic option. But for the transmission, you felt the Texaco product had some very specific additives that made it the "best" choice for the transmission. Do you have any new information that makes you feel more comfortable with some of the other alternatives, either Amsoil or LE, or is Texaco still your #1 for this specific application?
