Where can I buy some Transynd??

Eric @ Merchant Automotive, a vendor on this site, has it. Might be some others on this site. Also, check with a Allison dealer if they have it...

Any allison dealer.

Check the Allison Web site for a list of dealers near you, or if there are truck parts/service centers that sell heavy equipment (usually Allison dealers) near you, they might carry it also.

I called a place near me called Transaxle but they only have 5 gallon containers for $212.50, outrageous!!! How much will I need with spin on filter change and with a MagHytec pan?

Spin on is like a pint, but doesnt the mag pan say how much it holds??

Haven't read the instructions yet, but I think I will need at least 3 gallons of the stuff.

Mind as well get the 5 gallon can.

IIRC, the Mag-Hytec pan has a 10.5 quart capacity, which would make a pan drain almost a gallon more than the OE pan and fluid drain. Unfortunately, the $212.5 for 5 gallons is within the going price range for TranSynd. If it is an option to you, I'm sure some of the vendors on this site can get you either TranSynd or Amsoil Torque-Drive...perhaps for a better price.

Transynd is available in gallon size just keep checking at any big truck dealer, Kenworth Peterbuilt Int. etc

I called a place near me about 9 miles called Johnson & Towers. They service all series Allison's and have gallon jugs of Transynd at $43.69. Sounds like the average cost. I called a friend that works as a parts manager for a dealer nearby and he said the dealer was using Dexron VI on all models????? The Service Manuals I own from GM reccomend TransSynd Synthetic Automatic Transmission Fluid (GM P/N 12378515) for manual Transmissions (6spd)??? For all Auto Trans Dexron- III??? So what is in the Allison from the factory? Dexron-III? Just trying to save some cabbage in these rough times. Thanks.

That price on Transynd is on the higher end of average. If you would like to save some cabbage and want to use a clone ie Amsoil Torque Drive send me a PM I will give you some pricing and options.

You will need 3 gallons to do a Mag-Hytec Pan.

I get mine at local big rig dealer.

Dane is correct, $43 is pretty high, I bought 4 gallons from a big truck service place called WW Williams, they have lotsa locations nationwide,
$30.xx a gallon, or it could have been $32 just a few weeks back.
just go to ally website and look up dealers and call around

Pls read stickies in the forum for ally clarification for fluid.

Dex VI OR Ally GRAPE JUICE, save mucho mula and use Dex VI,
Wallmart has Valvoline max Dex VI for 14$ for 5 qts or gal

BBDC - I'm not sure what question you're really asking.

There is a sticky at the top. Read it first, then post up you questions.

Also, fill in your signature so we can see what ya got at a glance.

Just looking for what the trans had in it from the factory. Also I am not sure what a sticky is? Thanks.

The stickies are the red threads that appear above the blue ones. They're called stickies because they are sorted to always stay at the top. Here's a link to it. http://www.dieselplace.com/forum/showthread.php?t=223319

In regard to your question about stock factory fluid:

Any 1000 series tranny in the light duty trucks (up to 3500HD) came from the Baltimore plant, and was sent with either DEX III (prior to the change over sometime in 2006), or DEX VI (after the changeover).

The Indy Allison plant still uses TES-295 (or possibly TES-389?); Crafty1 could confirm.

My truck is a 2002 model so DEX III should work just fine. Thanks for the input.

Why not use Transynd like Allison recommends?

I am just concerned about using a Synthetic since my trans has 130,000 miles on it and I believe it has always had Dexron in it. I bought it used so I dunno what fluid it has in it. I do not want an intermix of fluids unless its ok? Besides Transynd is really expensive, ouch. Thanks.

DEX III works fine. Certainly TES-295 and the clones are better, but for "normal" service, (what was formerly) DEX III works just fine. (BTW - TES-389 is the new Allison standard for what was DEX III).

I realize that many people want to think that they, and their truck, are the manliest beasts on the planet. And to that end, we need the "best" that ever existed, and nothing else warrants consideration. But the reality is that about 99% of us fall into "normal" use patterns.

Allison, the company, considers "severe" service to include actions such as constant stop-go cycles with little, to no, TC lock-up, causing constant flashing of the TC. Ultra low vehicle speeds which limit the cooling flow over the cooler pack. Ultra heavy loads. The vehicles that qualify for this type description are trash trucks in the inner city, buses in the inner city, airport shuttles, etc. All driven by people who likely don't respect the vehicle, because they don't own it personally, and are quite possibly not motivated by their low wages, if you know what I mean. These types of vehicles get abused every minute, of every day.

Most here, on the other hand, panic if the tranny gages goes above 200 degF, pulling 7k pounds uphill for 15 seconds. People on this board border on pampering their vehicles.

Folks, most people on this site have no "need" for TES-295 fluids. It's fine to want them, but they are not "needed" for the safe, effective operation of our trucks. And DEX III type fluids are perfetly acceptable for pre-cutoff vehicles. Your change intervals will not be as great, but neither will your costs.

Awesome thanks for the info. I am considering checking out Valvoline ATF that has met the TES-295 specs.

I thought the TES-295 fluids were for the temps below -30 or something like that? Other than that the DEX V1 was the oil of choice?

As dnewton wisely notes, it's a bell curve when it comes to truck use — most are right there in the middle, neither just a grocery getter nor a severe service vehicle; and DEX is fine. Yet, it's not hard to get up there into the severe category without being a bus or a garbage truck. Slow RV towing in steep terrain and hot weather, farm work, like haying, or hauling construction equipment or materials in the mountains on undeveloped roads. The TES 295 fluids perform better than DEX in both extreme cold as well as high heat. IMHO, because of extended drain intervals offered by the TES fluids, the cost is a wash when compared to DEX. For general use (not severe) Allison recommends changing the non-TES fluid at 50K and the TES fluid at 150K. A gallon of DEX VI sells for almost $20 compared to a TES fluid for about $35. Sooooo, it would seem that a person is way ahead in both performance and cost with the TES fluid — as long as you are going to keep your truck for more than 50K.

My 03 has 110K on it, and I swapped out the Dexron III for Mobil 1 ATF back at 60,000. So far, so good....

Mobil 1 ATF is a synthetic, but it is not the same as the Mobil Delvac ATF, which is a TES 295 fluid (like Transynd). From Allison's point of view, only the TES fluids give you the extended drain interval.
