I did my GTS after I got it using the factory recommended fluid from Chrysler. You know, 20 bucks a qt times 4 stuff.

I'd be interested to hear what others are using too. The Tremec T56 rebuild manual says ATF. The OEM Chrysler manual says no ATF. I went with Chrysler on that...

Amsoil Severe Gear oil the last 60,000 miles or so. Differential as well. Change every 30K miles and analysis done. All is well.

I just used the castrol syntorque. There should be a stamp on the side of the tranny, I think it says anything else will void the warranty.

A tip on refilling the tranny, you can use a 3/8 piece of clear tygon tubing, about 5 feet long, run it down the drivers side of the engine into the fill hole and have someone slowly pour the fluid into the tubing from the top. It's a whole lot easier than trying to pump fluid up to the fill hole against gravity underneath the car.

Unless you have a lift and have done this a bunch before, then whatever method works best.

Look at your transmission case, it should have a sticker which states " use castrol syntorque or the chrysler fluid". If you put atf in there you will destroy your synchro rings. Tremec DOES NOT SAY use atf for your application. You can purchase Castrol Syntorque at some automotive parts stores.

I used a MityVac pump. Didn't spill a drop. Didn't need a lift.

Since I don't really know anything about the internal construction of the transmission as used on my Viper, or the lubricating properties of ATF, I just went with the fluid recommended by the factory engineers.

Here is some interesting reading:

Just found a website that has 1 gallon of the Castrol Syntorq for $51.
castrol Syntorq is the re-labled brand for GM & Dodge. My local dealer wanted almost $25/qt.

Viper T-56's used to come with ATF as the factory fill. At some point, Syntorque (under the Mopar brand name) was specified as factory fill and TSB'd for retrofit at address the complaint of neutral gear rattle (weenies) along with some level of added durability. Anyway, if you go to the Tremac web site is does specify Castrol Syntorque for "Viper" T-56's and ATF for all other. As someone stated, why take a chance on ATF? To save $60?

One can do a search to verify this as I researched it a few years ago.... As I remember, all orginal ATF equipped Vipers can upgrade to Syntorque/Mopar except 92 & 93's. Their syncros can not tolerate Syntorque. Side note: In the early days (92 ~ 96ish) the T-56 was made by Borg Warner.

Hopefully, Tom FOGoR can amplify and clarify

If Castrol Syntorq is the same as Dodge factory fill then why is it taking a chance to save $60? Did I read your post wrong?

I use AMS oil, and they warranty the use of it (I got it in writing, incl high performance applications specifically including Viper Days events). There is a specific oil they recommend, which is formulated for high temp applications. The Viper application is higher temp than other oils because of the close proximity of the exhaust. AMS website specifies Viper application. High temp manual trans fluid. About half the price of Chrysler product.

Redsled,

I was referring to the post by 01ACR/Viper. He seemed to indicate that the Syntorque/Mopar equivalent was a rip off versus the Tremac recommended ATF (recommended for non-Viper T-56's), though I might have missread him.

I've found Syntorque and the Mopar equivalent similarly priced.

NV4500.COM

For the NV4500. Is that a transmission type or brand? The advertisement sure doesn't say fluid for the T56 or Viper.

Until someone shows conclusive evidence that says their product is the right product, 80 bucks from Dodge is chump change. I didn't buy a Viper to save my money. I bought it to spend my money.

Update... The NV4500 is a tractor transmission? 2 PTO points??
Yeah... That'll work for me.

I'm not sure if there are any significant internal differences between the T56 in the Z06 vs the T56 in the Viper (other than the Z06 had a transaxle setup), but a ton of Z06 guys use (as I did) Royal Purple Synchromax. Royal Purple makes some good stuff, and I use their oil, too.

Here's where it gets a bit tricky, as the RP website recommends the following for Vipers:
Viper 1993 (DEXRON III) Synchromax

Viper 1994 & newer (GL-4: 75W85, PN04874459) Max-Gear 75W90

However, the correct product to use if the factory fill was Castrol Syntorq is Synchromax, according to several who have contacted RP. Apparently their reference chart on their website is incorrect.
:dunno:

I just don't get the desire here to save a few bucks on a $50K car.

I paid 4x $20 for the factory fluid.

There seems to be deals where you can save $30 on that 4qt fill.

If you drive 5K a year and change your fluid every 15K that's 10 dollars a year. Whoa.

The only research I did when I got the car and started looking for fluid is where the heck to get them. Not how to start substituting a different version.

If a Dodge or Borg Warner engineer would take over this thread I'll go away. Until the next save a dime thread comes along...

Money saved is money earned; however, some do like the feeling of getting bent over by the dealer. I will not support our local dealer who overcharges on every product and automobile. dave6666, the engine, tranny & diff fluids on our race cars gets flushed after every race weekend so the money does add up so when we can get the same, identical product that Dodge recommends at almost 1/2 the cost it just makes economical sense. I agree that saving $10 bucks a year isn't that much, but to each his own on that one.
On some of the transmissions that I've purchased from Dodge over the years some have had tags on them that say exactly to fill with Castrol Syntorq LT.
I've yet to see a Dodge, Borg Warner or Tremec engineer on thse boards to give the Viper owner the exact fluids to use, because on all their web sites they show different oils to use in the T-56.

I just looked at my on-line manuals (Mitchell) and think it's funny that it shows a 98 GTS to use ATF3, a 2001 GTS uses Castrol Syntec LT and an 04 SRT uses 75-85 synthetic fluid. Think maybe we make too big of a deal on fluids?? How many transmissions are blown from the wrong fluids?? Any idea? I don't think the fluid would prevent the nervous miss-shift.:dunno: :2tu:

I'm not so sure it's an issue of blowing the trans in the traditional sense, but rather maintaining the shifting integrity of the syncronizers. The wrong fluid could waste the fiberous ones. In the old Super T-10 and M-22 Rock Crusher days, they were brass and a lot more robust.

Well the fluid I have been using I bought for easier/smoother shifting, not money saving. I did notice it made a difference. So I'm happy with it and will continue using it. RoyalPurple Syncromax, and it cost more than $5 quart. Hopefully Tom will see this thread and give us his insight on this.

Yeah, I don't know what the comment about saving $$ is when everyone knows the dealer will bend you over and that none of the auto manufacturers produce their own lubes, anyway - they are just relabeled products.

As Madduc indicated, most switch to RP because of it's benefits regarding shifting feel. I'll be doing likewise...
