Allison 2000 Info

[EastCoastCB]

I'm wanting to do a fluid and filter change on my Allison 2000. I've got the spin on filter. There's another filter that does underneath inside the pan.
I can't find any good info, at least what I'm looking for.

What fluid do I use?
Do I drop the pan and replace the filter that's in the pan?
Do our 2000's have the "deep pan" or "shallow pan"?
Any info/help appreciated!

There's a lot of service info. I can't find anything about a second filter.

Thanks. That's all the stuff I've found.
Hoping to hear from some owners with real world experience servicing these and keeping them alive.

A second search resulted in this;

It's a photo of the internal filter.

the main approved transmission fluid on an allison transmission is Transynd. I think you can still use dexron, but I am running Transynd in my 1000, and in the 545 that the DEV has.. flushing a trans completelty is a bit pricey and time consuming if you change from standard to synthetic fluid.

I use Mobil Delvac 1 in my MD3060. I am unfamiliar with the filters on your 2000, however.

If that were my bus, I'd take it in and have trans serviced the first time at Allison tech. They will make adjustments and see things you won't. After the first service, you can keep-up the regular maint.

I am taking my MD3060 in for it's first service soon. Unless I find out how much it costs....

Here is some info

Plug in your data and it will tell you everything you need to know.

Most times, the internal filter is only serviced when the unit is overhauled.

Anything certified tes295 is the current recommended fluid. I use the Shell brand.

The year is what determines fluid usage. Up until the mid 2000's dex3 was acceptable

Type your model # into here My Transmission and you'll see what pan it came with from the factory, along with other options.

Is the internal filter the one that's in the pan? They're famous for not even being seated in the hole properly and often are found just floating around in the pan. The pan gasket and filter are only $25 and available at oreilly. Just wondering if there's some reason not to change it.

So for a normal service in my driveway do I drop the pan and do the filter in the pan?
Or just drain it from the plug and change the spin on?

I'd like to service it regularly and always have fresh, clean fluid in there at all times. I've seen quite a few forum members totally neglect their 2000 even when a light comes on.
I'm just trying to get the bus 100% up to snuff, and I'd like to do it all myself.

I guess. I have a lot of respect for the jumble of parts that is the modern transmission. When they work...they are great, but when they don't...$$$

I need mine to go in and have 6th gear unlocked anyway (hopefully).


Post some pics/video of the red mess as there isn't much info on that trans here.

the only difference really is deep pan vs shallow pan.. the filter in the pan on some of the allisons is different for deep vs shallow.. ive never considered a fluid / filter change anything that a DIYer cant do.. these allisons are run of the mill rear-drive fully-clutch automatics.. standard rules apply.. clean fluid, clean filter, clean out the Pan really well so you dont stir up any junk.. chances are it has standard dexron III fluid in it and you can put the same back in.. the 'my transmission' site can give you more details about it.. i think even the fluid type fro factory ..

I only run TranSynd in mine because it was brand new and dry so there was no flushing.. and it was recommended for being less likely to break down if it got hot..

that 2000 is less likely to get hot.. esp since you have full rad / CAC.. (maybe an AC unit in front). so you likely wont have any heat issues with it..

I think our buses would all have the deep pans.
The shallow pans are mostly in pickup trucks. Supposedly the shallow one is like 3 and 3/4" and the deep is 4 1/2". Or something like that. Also the shallow one is supposed to slant down sort of like an oil pan and the deep one is constant depth with no slant on the bottom.
The filters in these pans fall out frequently enough that there's a filter lock kit to keep them in place.

They're only $27. I think I'll pop for one.

[EastCoastCB]

I think this is a 1000, right?

Should be the same, they share the same filters and stuff.

[EastCoastCB]

This one's the easy part.

The wix part # is 57701 at oreilly, fwiw.

So just to clarify- The filter in the pan pictured, that's not the "internal" filter that's only supposed to be replaced at overhaul, right?

If its filled with TranSynd now, will it be ok to drain what I can and fill with a more affordable brand that still meets the requirements?

My fluid isn't too pretty looking. Its not burnt, but it definitely needs to be replaced.
I wanna go the extra mile on this bus' maintenance. I don't like to "flush" transmissions, so I'm planning on doing a fluid change on it every thousand miles till the next oil change. Probably excessive, but I don't mind the cost. I really wanna bulletproof this thing as much as I can. With the low miles and nice condition of this bus I think I could keep it on the road a long time.

You don't have to throw money away though.

Drain and refill the trans. Drive a few miles to thoroughly mix the new with the remaining old.

Drain, change filter and refill.

Done. Anything that remains is so well diluted with new by now it will be no problem.
