You can purchase the extraction pump from JG when you order your sample kit. I bought one for oil and one for coolant. Once you decide to start testing your oil, tranny and coolant it's a small price to pay for the extraction pump since you will use it each time.

Any of you guys who are planning on owning your coach for a few years, should think about installing a sample port on your transmission.

JG Lube will sell you the kit for under $30 and it takes about 5 minutes to install. There is a pressure port low in the driver’s side of the transmission with a threaded plug. The port installs there & then it’s a 5 minute job to pull a clean, hot fluid sample.

Steve thanks for posting this. I read about this a couple years ago but had forgotten. I also installed a Fumoto oil drain valve on the last service so I'll start pulling oil samples from there. I just looked for the sample port drain plug on the JG site but didn't see it. I think I want one myself. I'll give them a call.

Comments?

ABSOLUTELY!!!!!!!!!!!!!

I think it would be worth $10/gallon to be blessed by Allison.

Once out of warranty, being blessed by Tom is good enough for me.

Walk a newbie through?

Tom,

My Allison 1000 6 spd is pushing 51K miles. The Workhorse maintenance schedule says the fluid and filter should be replaced, but I've heard that the synthetic fluids can do 100 K with no problems.

I've attached my sample report. Can you walk me through the numbers and advise me?

First... Your results are through JG Lubricants. The "comments section" is the part you want to pay attention to. If you required immediate or near immediate service, it would tell you that. I Suggest you call Tom Johnson, at JG. He is more than willing to go over what the test results mean. He can be reached at 877-971-7799.

I'm here to help with your questions about Allison Transmission fluid specifications, TranSynd, oil and coolant analysis, etc.

Let me know how I can help.

PS: You can call me "Mr. TranSynd" if you like..
Hi Mr T. My name is Dick. Can you tell me if an ECM code 151-14 has anything to do with my Allison? Thank you.

Sorry, but that's not my area of expertise. I suggest you contact the engine manufacturer or "Google" that particular ECM fault code. If this were an Allison related problem, then you should be able to call up the Transmission Control Module (TCM) fault code using your Push Button Shift Selector.

Bob,
See the attached "markup". Your report shows you're running a TES-295 fluid as evidenced by the overall report and specifically by the viscosity and oxidation numbers (shown in the green circles). Wear metals are low and only indicate what I would refer to as "break-in" wear. Don't worry about the TAN number being flagged. It will eventually go up more but that will take a very long time (probably years). Just check it again next year and you'll probably get around the same values. Hope this helps .... but, call me if you'd like !!!

Hello Tom,

Allison 3000 ?and CAT 330 - Freightliner 3126E). On several occasions I have taken the MH out, and after driving more than 20 miles I continue to get an OL-70, indicating that my temperature is too low for a reading.

Is this normal? I changed the fluid/filter 200 miles ago (Transynd) - while I have received a single OL-OK reading, today I drove much farther and got the OL-70 reading.

Any thoughts why this is happening, or is this normal. Just not sure how to check the trans fluid level when this happens.

Thanks.
