Std 5spd transmission oil change

[nopowerforme]

Hi All, I have been considering changing the oil in the transmission any recomendations on what to put back in? Is amsoil the way to go? I have the amsoil in the rearend.
Another question how do you drain it out I haven't looked yet. #ad

Any help you guys and woman could supply would be much appreciated.

Since adding the Tst uprate kit I have not towed my trailer but will be moving from ID to MN through Yellowstone and will post my EGT's, Boost and Fuel milage when I arrive in International falls

Thanks

nopowerforme,
You will get several different opions on which brand fluid to use.
Most any GL-4. But Castrol is the strongly recommended by Dodge and NV. The Castrol is formulated for this trans. Joe D. who used another name brand switched back to the Castrol after a tour of The Standard transmission plant.

The Castrol can be bought at a(cough,choke) chevy dealer(cough,choke,choke, cough) in smaller quantities than at Dodge dealer.
Amsoil is good quality fluid and they say they will stand behind it.

To drain trans fluid unloosen bottom bolt on PTO cover on side of trans. This is where the warning labels for the "castrol fluid only" are located. You should have the PTO covers on both sides of trans.

Other post on trans fluid brands will follow.
Good Luck!

Amsoil rocks in that transmission! And yes, they do stand behind it. If your truck is a "keeper", I highly recommend it.

The Castrol is great stuff, just not competively priced.

Can not go wrong w/ a high quality SYNTHETIC GL-4 such as Redline MT90.

There is much controversy on the GL-5/MT-1's.
Do a search & you'll have enough reading material for a month!

Amsoil is a "blender" just like Redline & others that use some of the very best synthetic base lubes on the market.
"Traditional" thinking says that there still is a risk even when using GL-5/MT-1's.
Amsoil won't comment on how they are different & how they accomplish this multiple rating. They just ask that you trust them. Petroleum Technology is like the computer technology, it gets better as we speak, so who knows. A lot of people use it & seem very satisfied. Its too pricey for me anyways. At least for what they get for it at the NAPA & Carquest around here. It cost me $32 to change to the GL-4 rated MT90 & their base oil is just as good as the Amsoil so I'm happy.

Here's some reading for you! https://www.turbodieselregister.com/ubb//Forum1/HTML/003598.html

Oh by the way, here's my take on Redline.

Studying the data sheets of Syntorq, we have no doubt that it is excellent oil. Of worthy notation; Castrol uses a hydroisomerzation process to achieve what is legally classified as synthetic oil. But this lube is really the result of the latest refining technology imparted upon mineral oil. It is not a synthetic in the “traditional” sense of the word, but however does have chemical properties equivalent to synthetic oils and can be produced at a significantly lower cost. That’s a pretty good combination. However, there are many types of synthetics that perform even better than traditional PAO’s (Principal Applications Olefins Oligomers) or hydroisomerzied oils. One of these better performing base stocks is Polyol Ester. The Redline Synthetic Oil Corp uses these extremely high quality base stocks. The Chief Chemist at Redline is Roy Howell, formerly of Lubrisol. Lubrisol is the main supplier of additives to the petroleum industry. I feel comfortable in his qualifications to get the additive chemistry correct. Redline produces a couple of synthetic GL-4 lubes specifically made for manual transmissions with soft metal synchronizers. This lead me to their MT90, which has the closest rheological characteristics to Syntorq of any lube I looked at. It also has a very high V. I. of 175. I can report that after changing to MT90 in my own truck, shifting quality did not change. It shifted smoothly with Syntorq for over 100,000 miles and still shifts smoothly with the synthetic GL-4 I changed to, even under the cold conditions present here in the Rocky Mountains. The Castrol Syntorq is so good the OEM feels comfortable making a “fill for life” lube and since MT90 has a better base oil than even the Syntorq, I feel comfortable that it can take long term abuse just as well if not better. I definitely won’t have to worry about any potentially corrosive EP additives like I would if I went with a GL-5. Going by competitive automotive pricing standards, at $7. 95 per quart the MT90 is an expensive lube but not nearly as much the $25. 69 per quart that the Syntorq goes for. The only drawback of MT90 is its limited availability. Race shops will usually carry it. To find out if one is near you go to Redlineoil.com and search their online dealer listing. I’m sure there are other high quality GL-4’s available also, if you want to do the research.

Syntorq’s only fault is that it is not competitively priced. However, Syntorq is specifically tailored for the NV4500, so either use it or find a high quality synthetic GL-4 like the MT90. You can’t go wrong by staying within the OEM’s recommendation. The NV4500 doesn’t need the extra protection of a GL-5, so why take the risk? Your best retail pricing option for Syntorq is General Motors. Ask any GM dealer for P/N 12346190. It will be substantially less than any other dealer. You can also obtain a wholesale price for Syntorq plus shipping charges from Standard Transmission of Texas.

mikepvg, Thanks for the reading material... . all said and done, since I pull a 33ft 5er that weighs 12,500 lbs and am a full timer that moves around a lot, I think I'm going to GM and get the P/N 12345190 oil. I like amsoil but am not willing to take the chance that I will change it as often as I should.

i'm a young 60 and going strong but... ...

Can't thank you all enough for great info and places to get more.

I have gotten two calls from guys who haul heavy loads and run the Castrol. They both had between 100,000 and 150,000 miles. They both had 5spds that looked "burnt up".
Seeing what they just payed for rebuilds, they were ready for a change.

IMHO,(meaning no proof) the Castrol was engineered to make these trannys live past warranty, and that was it. Most people will get away with it, as they change often, don't haul heavy loads, or trade their trucks.
The Amsoil has been in these transmissions since 1994. No problems. If it makes you nervous, take a sample every now and then. If the Amsoil ever causes a failure, they will pick it up. Sort of like an extended warranty. Costs $14. 00 to take a sample.

Someone should call Castrol and see if they will pay for a failed transmission at 150,000 or more.

Please let me clarify. . . I did not try another lube and go back to Castrol. Castrol is all I used--with two changes of lube--for about 100,000 miles in my NV4500. Standard Trans at 1-800-std-tran offers a pretty good price (about $60 with shipping) on a gallon of Syntorq (the required amount).

I recently dyno tested 5 lubes for coastdown horsepower drag in the NV4500. [Thanks to Diesel Dynamics for dyno time, expert operation of the dyno, and donating one of the lubes I tested. ] Results will appear in TDR 33 this Fall. Three name brand 75-90 lubes, GL5 or 6, were tested and had noticeably more drag than Castrol.

One other lube, Torco RTF, had about the same drag as Castrol. It is rated 75, 80 and 85 weight, and GL-6. Torco said it does not have the "aggressive" additives that are hard on soft metals. They have tested it extensively in road racing with trannies such as the Corvette 6 speed. They believe there won't be any problems with the brass, synchro liners, or bonding resin.

I have been using this RTF for a few weeks and it seems to perform fine with respect to shifting, noise, and temperature. If you choose a lube other than Castrol, I feel you need to monitor trans vs. diff temp for a while and under different conditions to ensure the lube keeps the trans as cool as Castrol does.

My transmission has 85,000 on original oil, and with everything I have been reading plus input from others, I have decided to put in Amsoil oil. i will keep an eye on it, and take a sample but I think for the type of towing and lenghts of time towing I will do okay.

I have ordered the oil and will change it this Friday .

This is my story and I'm sticking to it #ad

What lube to use???
I have never charged anyone for my study's
"experance" into the nv transmission and how to make it live. i dont sell anything BUT with with over 700K (and the records to back it up)I challange anyone to prove me wrong. Spend what you want for lube. it is ano out of my pocket!!
But "syntec" 75w 90 may not be the recomended lube But tell me why am i so special that it has worked (and still is) for my application & miles.
My first choice is the mfg of the eng lube & rear gear lube,but there additivites of ther 85w 90 are a little to high for the transmission .
Century/fusch/&&&&--!!! is packaged for the star's (T) lable.
As i said it is not my wallet but "syntec" gear lube will cost around 7-8 $'s will work just fine.
I went with a spec only , Looked great,cost more, in a chassie grease once , and in a month ,in a fleet of 124 power units and 240 trailers there claim to fame didn't hold up.
As i drain once a year (miles around 100k)
Can i be this lucky if only X or $$$ y or $$$$ z work!

It would appear that your experience is the proverbial fly in the ointment of the GL-5/MT-1 theory.
It certainly proves one can get away w/ using a GL-5/MT-1. But is there still a risk? Many people think so, including Castrol.
A lot of these "answers" are only speculative. In the world of science & chemistry, one case (unfortunately) proves very little. i. e. A friend has chewed Copenhagan for over 60 years & hasn't had a single problem or symptom. Does that prove its safe? The people that got mouth cancer certainly don't think so. I would like to think that the guy w/ 60 years experience proves that its safe since I love my Copenhagan (especially marinated in a good Tequilla) but I know better so have curbed my habit accordingly. It just depends what side of the fence your on.

I think its great that you got that kinda of success w/ Syntec. But then you seem to know what your doing regarding checking & monitoring your equipement etc & treat it in a very professional manner. Most just put the lube in & forget about it. Some even abuse their equipement & do not realize their equipement has limts.

Syntec around here costs $10/qt @ PepBoys & in theory might be risky. The specifically made for syncronized trannies MT90 cost only 7. 95 & in theory has no risk. And I like to put it in & forget about it for 50K miles regardless how many years pass.
