6 SPEED GEAR OIL

[WCrovo]

I am going to go to dealer and find out about changeing to synthetic gear oil. Side of trans says anything but Texaco whatever will void warrenty. I called Redline and was told MTL would be recomended replacement lubricant. If the trans oil looks anything like the OE diff oil after 1,000 miles it needs to go. Also I did not see a drain plug on trans. Whats up with that?

Walter,
That sticker is meant to scare people into buying the lube at the dealers. They will not/can not void your warranty for putting a different brand in that is an equivalent or better.
I suggest Amsoil Series 3000 5w-30.
Don't even start with the Toilet paper filter bit, that was not Amsoil!

I got this second hand, so lawyers feel free to correct me, but DC may have a loophole in that law: If they specify only one fluid, they must give you free fluid during the warranty period. Since the fluid is a "lifetime" rated fluid, that means zero free refills. Now, if you're happy with a lifetime of 100,000 miles, no problems, but if you want more like 300 to 500,000, then you may have to pay for one or two fluid changes with the specified fluid, then change to Amsoil at 100,000 miles. Or, take your chances, and change to what you believe in sooner, warranty or not.

The lube in the 6-speed is a Texaco oil. I think I read on another post that someone had tried to use a different oil in a Pontiac transaxle, that specified the same lube as ours, and had problems shifting. If I'm not mistaken its Texaco MTX 1874. I've heard its only available in 5 gallon pails or larger but that you can get that pail for less $$$ than what you could buy the amount you need from the dealer. If you want to change the oil then hook up with a couple of people you know that have the 6-speed and split the cost. Just a suggestion.

Hyde,

That was me with the Grand Am, and I ended up going back to the suggested OEM fluid, which is the same as our trucks require. I have heard others are using the Amsoil as suggested in this thread. All I know is that an engine lube did not work very good in the Pontiac, maybe it will in the Dodge???

I've always been an Amsoil believer, so after I installed my transmission temp gauge in my 6 speed I naturally replaced the OEM oil with Amsoil 75/90. I immediately noticed a slight grind when shifting from 3rd to 4th #ad
but it didn't happen every time. transmission temp never got over 140 deg. I first thought that maybe I was doing something wrong but after about two weeks of the same thing I though this couldn’t be right so I posted a thread on this forum and low and behold I'm using the wrong oil #ad
. I immediately drained the 75/90 and replaced it with OEM oil and the shift grind disappeared #ad
. There's one thing that I found very interesting after running the OEM oil for a while, there was NO difference in the transmission temp between the 75/90 and the OEM oil. #ad
What is it about the OEM oil that makes it so special? I'm currently running the Redline 75/90 in an attempt to quite the "neutral grind" due to the installation of the McLeod duel disk clutch. I'm happy to report #ad
that so far I'm NOT experiencing any problems and transmission temps are still the same as with the OEM oil.

Cliffman,
You forgot to mention you never tried PURE Amsoil 5w-30, you dumped some type of additive in with it.
You may have noticed a temp drop with straight Amsoil, can't tell if you contaminated it with another product.

If you are trying to maintain your warranty, why change? DC has made their position clear in both the owners manual and with the sticker. I have yet to see any objective data to indicate that there is a product superior to the oem fluid for the application. My truck has 26000 miles of hard towing. By appearance, the original oil is still good. But I picked up 5 gallons of Texaco MTX fluid and will be doing an oil change and inspection.

[Cliffman]

Your right MGM. I failed to mention that between the Amsoil 75-90 and the 5-30 I ran the OEM oil. My mistake. I just thought that the temps were so low anyway it wasn’t worth mentioning. I will correct my earlier post #ad

 

[Cliffman]

Len,

How do you know for sure that the OEM oil for the NV-5600 is this Texaco MTX and do you know if it's synthetic or not.

 

[WCrovo]

Len I have found synthetics hold up better. I know my diffs look crapy right away so I don't think DC uses the best stuff. My transmission performs perfectly. Want to keep it that way. Untill I find out for sure Texaco will stay.

 

[Len]

Cliffman.
The tag on the transmission references Texaco STF1874. but the more common Texaco terminology is MTX. If you work hard enough you can find it on the Texaco web site. I don't believe it is synthetic.

 

[Bob Cochran]

Everyone can correct me but I believe the owners manual says to change diff and transmission to synthetic if doing heavy towing. I have thought about changing to this synthetic when I get to towing heavier but have not talked to the DC 5 star dealer to find out what weight or brand. Is there a Mopar synthetic they will use?

Bob,
My owners manual recomnends changing the differential lube to synthetic for towing.
They do not even specify a need for periodic changes of lube in the 6 speed transmission. But they do recomend only one oil, part number 4761526 I believe. And the tag on the transmission gives the DC, GM and Texaco numbers.

Bob,

Sure Mopar will sell ya a synthetic fluid, I advise you to be sitting when they quote you a price. And I do not believe this is a case of you get what youpay for. You would be better off going with Amsoil or LE in my opinion. There has been a vast amount of information posted on these and other synthetic lubes, time to start doing some homework.

I was going to change my fluid as I now have 26000 miles and count. Well I check at my local dealer and they told me it cost $10. 50 per quart or about $50. 00 to change the fluild so I thought no thanks I will go elsewhere.

I wanted to change the fluid in my 6 speed at 10K 1)just in case there was some break in weat metals in the case and 2)it just seemed like a good idea. It was clean as could be--but now I know.

Dealer wanted $5-something per quart. Texaco dist. wanted $55. for 5 gallons. I bought the 5 gallons, seems that ought to have a long shelf life so I plan to change about every 25K

Sure, the burden is on DC to prove that your replacement oil caused the transmission failure should that happen--------BUT, Ever try litigating with any deep pocket oponent? Got an extry $10,000 or so to prove your point. They have staff's of attorneys ready to tie you up in court for the next several years, and you can bet the lawyer you ask to represent you against such an oponent is going to want many thousand (far more than the cost of a new transmission) up front before you even start, because he will know its going to be a very long difficult battle.

While the theory that they "have to prove the failure was caused by the non-prescribed product," sounds nice, the theory has little to no practical value to an ordinary person, except for items of such small value that you can process it in small claims court. Some States have provision that for smaller claims (typically under $1K or so) the claimant can avoid getting lawyers involved.
I am not knocking lawyers ( I am one), its just a fact of life in litigation.

Len~ Yep just looked a owners manual again and you are right recommend going to synthetic for dif does nto say anything abotu transmision. Sorry did not mean to miss lead.

ituffram ~ Some one told me the Dealer charged in $146 to change 6 spd oil and i don't think it was synethic. Probably woudl be a bad case of shock to hear waht the Mopar synthetic costs but then it is life-time right? Least they say so. Your right need to do homework as I plan on changing 6 spd and diff to synethetic in the future.

 

[1tuffram]

Bob,

I have no idea what the oil for the 6 speed costs at either the dealer or aftermarket ( I own a 5speed).

Years back when getting ready to change the gear lube in the axles for the first time I inquired the dealership for the cost of synthetic gear-lube. Memory is hazy, but I believe the parts counter quoted my something like $20+ per quart of "Mopar". I asked him to repeat the price because I thought I didn't hear it right.
Needless to say I went home and called an Amsoil dealer I found in the TDR magazine.
