Todd why not ask the person in charge of the maintenance of all those "cop mobiles" where you work for the name of the fleet supplier of oil. If not just look through the yellow pages and find the suppliers and call them. They probably have what you need in stock.
Good idea Dennis except our county has adopted a policy where they must purchase everything locally if available. So basically they buy from a local mom and pop place like everyone else. I'll see if NAPA can get it special order, supposedly they guarentee to have it the next day if they don't have it in stock. Just order a couple gallons if I can. Be a few more weeks before I'm crawling under her anyway (I hope). Physical Therapy starts this week for my knee. I am few weeks behind due to the blood clot I developed. I was already warned by the therapist that, "it won't be pleasant catching up."
NAPA tells me that the Sta-Lube (SL24239) is an 85w90. Will that work in the transmission (gearbox) without any problems, or it this too heavy a grade?
Todd well that policy is very gratifying to read. Here in Golden Colorado the policy is alot different since it's controlled by Jefferson County. Big is better and have no truc with small business appears to be the motto.
Sorry to read that your injury is taking a long time to heal. I can tell you a quaint story about my nephew the London Met and his recent confrontation with domestic violence perpertrators or wife beaters as he calls em. Not for this section of the forum but I can publish it in the general section if you and others are interested.
Take care

Todd,
Your transmission/gearbox has 30wt motor oil in it. It runs cooler and shifts easier than GL4 or GL5 and has no issues with corrosion. It is a full synthetic Amsoil. 30wt motor oil=80w gear oil.
You can use a specialty transmission oil like MTL or MT90. There is no load on the gears like a differential so it isn't critical. Keep it full of good oil and drive it like you stole it, officer.

I am interested in your post.
Why would your friend swear by Redline oil? In fact can anyone who contributes to this board give real factual information on the claimed superior performance of one brand of oil over another; After all they all should comply to an API and SAE spec GL4 compatibility etc otherwise don't use them.
I can give some credence to an operator of a large fleet (like the Swiss Military for example) who could table factual evidence of one oil brand/weight over another with failure correlation and sample parts to support the claim over a period of say 5 years.
From my experience of fixing buggered up Pinzgauer gearboxes the biggest problem is lack of oil not one designer brand over another that is commercially avialable in the high street. I have fixed five units since January and all have bar one suffered from incomplete/careless filling procedures the other was driven hard & put away wet with water in the works. One of these had Amsoil it it prior to failure, so a lack of oil probably won't help you out in this instance with a designer oil.
I suspect most of the shifting problems people experience is due to clutch problems or other factors such as linkage adjustment. The ZF gearbox is a quality unit and the only item I have seen that has prompted me to check frequently is lift on the rear of the mainshaft causing oil loss from the seal and then contingent bearing failure of the input shaft if the oil level is neglected.
I suspect the real answer to much of this hype lies in advertising. In the US there is by far an unusal acceptance of advertising as fact when in truth much of this is just image. My postings on Ashland Oils and Valvoline is an example. I equate this frankly to my past preferences to exotic swarthy looking dark skinned supine like non anglo saxon females. Why I couldn't tell you, I just liked the package. BUT. As the wrinkles on my face show experience, questions concerning packaging mostly prove that in a can of oil the contents are much the same, unlike females that may be a peach today but quickly turn into a stick of old rhubard tomorrow.
Bye Bye

Thanks for posting the link,but with respect this tells me nothing.
I see no reference to the fact that this product will work any better in a ZF 4 or 5 speed gearbox as used in the Pinzgauer 710m/12 of the 1970's vintage. The manufacturers of the gearbox (ZF) have no specific reference to using this product. In fact I don't see anywhere where they certify that brand of oils. If they do perhaps you could point them out.
If you do go delving into ZF specified/recommended lubrication there is an API spec to adher to nothing more nothing less.
The specific loadings imposed on the bearing surfaces/teeth flanks of this system transmission are so minimal that ordinary high street available oils to the API spec work just fine. There are many thousands of truck/bus and commercial operators who use these oils on a daily basis in much higher loaded applications than a recreational Pinzgauer or even those use for the occasional business operation like tourist hauling.
We regularly push big rigs around with one (Pinzgauer that is) and drive at 60 odd mls/hr and we don't see any detrimental effects in using Texaco GL4 grade oil. (but then I suppose thats small beans having only completed 46000mls since purchase) The real test is to see the levels of wear at say 150,000 mls.
So again can anyone provide quantitive data on the benefits of using these designer oils. Specific component wear, over mileages etc, even reduced fuel consumption if such controlled data can be produced.

Dennis, though not applicable in the Pinz the Mobil synthetic products for engine, transmissions, differentials all have passed the ASTM tests with flying colors. I won't post those links but they are out there. Guess that is why they cost so much...but hey, they go longer.
The only synthetic I use in the Pinz is the GL-4 rated Redline in the tranny. No one else makes a GL-4 that I have found in a synthetic. I guess the bottom line is you can put what you want in as long as you monitor it for appropriate fill level.
I hate doing oil swaps so the long life synthetics make sense for me.
