Thanks. What should I be looking/listening for to know if there is damage?

cgflyer- its the brass and bronze parts that are affectted so the synchros blocking rings and bushings, namely 2nd gear has a i guess its bronze "lining" when this is wore it allows the gear to not ride true to the shaft and will pop out of second gear when you let off the accelerator. the synchros , you will notice "noisy" shifting between 2nd and 3rd especially but also when you go up from 1st - 2nd. also the bushing in the xfer between the output shafts is bronze and is already subject to fast wear if your rig is equipped with lock out hubs up front. there are also a few thrust washers lined in bronze.
fwiw evidently the GL-5 oil is far and away the most common out there and seems most are using it. the three trans and xfers that i have rebuilt in last year ALL had brass/bronze particles in them in at least moderate quantities all thrust washers were severely scored, the thought never crossed my mind about oils and additives. the very first one that i did was my own and it has been sitting nearly a year with GL-5 in it (it has not been driven) so i may be ok with a flush and proper oil. this has been an excellant and informative thread. Sean, Sam or whoever has the ability , can we make this a "sticky"? cheers Rick

Thanks. The transmission has always had a whine but I have not had any issues with it popping out of gear. I have orders the GL-1 from Napa. I plan to change the oil, drive it for a couple days and then change it again. Hopefully that will get most of the GL-5 out of there!

I just picked up a 5 gal pail of Conoco Synthetic Tranoil 50, GL-1/MT-1. It was recommended by my Conoco oil guy that I use at work. He said the most of the "knowledgeable" shops that he supplies use it. He was aware of the GL-5 concerns. Cost was $160.50/5gal.which comes out to about $8.00/qt. I was looking at Redline MT90 @ $16.00/qt. Anyone have any experience with the Conoco product?

I think some have had issues with synthetic oil in the tranny and there may be a reference to it in this thread.

Didn't notice this post before I posted a similar one about my recent experience with gear oils for the transmission and transfer case on my 48.

Just wanted to followup to my "08 June 2011 at 11:15pm" post in this discussion. I did end up buying the 5 gallon pail of the Valvoline GL-1. Got it at Grainger's for like $90 and used it and so far so good. As per that prior post NAPA could get the Valvoline product as well, but I think they ended up being around $30 more. The Valvoline product number and some additional identifying information is in that prior post.

I didn't think it was the sythetic make so much as the GL-5 rating. Here's the info from the cut sheet...
Triton Synthetic Transoil 50 is a full-synthetic SAE 50 transmission lubricant designed for use in heavy-duty truck and bus manual transmissions operating in extreme temperatures and/or extended service intervals. It combines improved low-temperature properties with outstanding oxidation resistance and thermal stability at high temperatures to provide excellent all-climate, year-round performance. It has excellent shear stability and antiwear properties to protect synchronizers, reduce component wear and promote longer transmission life. It is particularly recommended for use in newer, higher-torque manual transmissions coupled with increased horsepower engines. It is fully approved for extended drain service in Eaton Roadranger ®transmissions. Applications Triton Synthetic Transoil 50 is recommended for use in ArvinMeritor, Dana Spicer, Eaton Fuller, International, Mack and other heavy-duty manual transmissions that require a non-EP gear oil (API GL-1/MT-1) or a MIL-L-2104D (API CD) quality engine oil. It is approved for 500,000-mile drain intervals in Eaton transmissions under the Eaton Roadranger ® PS-164 Rev 7specification. Triton Synthetic Transoil 50 meets or exceeds the requirements of: • API Service GL-1, MT-1 • ArvinMeritor O-81 • Dana Spicer transmissions • Eaton Fuller transmissions • Eaton Roadranger ® E500™ (PS-164 Rev 7)• International TMS 6816 • Mack TO-A Plus • MIL-L-2104D • ZF Freedomline transmissions Features/Benefits • Extended drain, all-season performance • Outstanding oxidation resistance and thermal stability to minimize sludge and varnish formation • Excellent low-temperature properties for easier shifting in cold weather • High shear stability • High load-carrying capacity • Protects against component wear and gear micropitting The MT-1 thing kind of baffles me but, I figure I'll give it a try anyway... |

I am in Australia; we have Penrite Oils and they sell Penrite T90, an API GL-1 oil, specifically designed for vintage gearboxes, which will not corrode ferrous and non-ferrous materials. I discovered that after I found the gearbox oil in my 1946 CJ2A was a nice yellow colour.

The sources that I have read state that MT-1 designates a lubricant with extreme pressure (EP) additives designed for non-synchronized transmissions. That is not what the T-90 is which is why it has the yellow metal synchronizer rings. Some EP additives destroy these metals. I would be cautious about using that lubricant.

Pennzoil Synchromesh Manual Transmission Fluid.
Has anyone checked out this stuff? According to their website; "It provides excellent oxidation stability, low temperature performance, excellent synchronizer performance and compatibility with yellow metals, such as bronze, brass and copper components found in manual transaxles and transmissions." an aanlysis of the oil found that "consist of a 5W30 non-detergent oil with a friction modifer and an EP (extreme pressure) additive". The use of EP additives concerns me. More details can be found here http://www.stealth316.com/2-pennzoil-synchromesh.htm |

I found that product at Advance Auto and, after looking into it, found that it was designed for certain GM and, I think Chrysler, contemporary vehicles. The viscosity is not correct for our T-90s, I think. Since NAPA carries the straight mineral oil called for and the product number is known for the US stores, why take a chance on something where the label mentions only certain vehicles?

Could someone elaborate on this process? Do I drain what's in there first, then add kerosene? How much? I pulled the transmission cover off Bugger yesterday to take a look at things. (Can't get into 2nd while rolling unless I double clutch) Level is low, but at least its not a rusty mess!  Headed to NAPA later for GL1

Call NAPA first. They had to order my GL-1 from a warehouse. It took only one day, though.
I would drain the old stuff first and then add the kerosene. |

What about this oil sold at Tractor Supply for Ford tractors??
http://www.tractorsupply.com/traveller-reg-ford-tractor-all-mineral-90-transmission-fluid-2-gal--0806600 Is this stuff the correct viscosity? Or is the GL 1 NAPA oil the only choice right now?? Great thread by the way .... !! |
