Do you all have any experience or words of wisdom for AMSOIL vs MOPAR for transmission fluid?
Does anyone with a Gen 3 have the owners manual that can tell me what I need for transmission fluid. Or attach a link, that would be helpful. Thanks in advance.I have a 2008 and I strictly followed the guidance of products to use in my owners manual for all fluids. I was unsure when all the fluids in the car (other than motor oil) was changed last so I had all the fluids flushed for peace of mind a few weeks ago. Why not stick to what the owners manual recommends?
For the most part, this will serve you well, but there are times when there are legitimate reasons to stray from the owner's manual recommendations. The best examples I can think of are with engine and differential oils, specifically for a Gen 4.I have a 2008 and I strictly followed the guidance of products to use in my owners manual for all fluids.

The Viper rear axle lube used from 1992 – 2010 (with Dana Trac-Lok and Hydra-Lok differentials) was the corporate ‘standard’ MS-8985 synthetic 75W-140… this was the same generic 75W-140 used in many other Chrysler products. For the Viper, the MS-10111 limited slip additive was also required. Viper fill volume to the bottom of the fill plug is about 48 oz. The factory fill at Dana was pre-blended with friction modifier at 5% by volume. For Service, the 75W-140 and the friction modifier are sold separately and the dealer/customer need to do the mix. The correct friction modifier amount for the Viper axle fill based on the 5% blend is about 2.4 oz. Unfortunately the stuff comes in a 4 oz. bottle I believe, so somewhere along the line, it became popular to put in a full bottle. A little more or less does not cause problems, but the correct amount has always been 5% by volume. Because it was a generic synthetic 75W-140, the MS-8985 fluid came from a variety of fluid suppliers including Shell, Texaco, etc.
Over time and miles, the friction modifier tends to ‘burn off’ and become less effective, causing some chatter when turning or other NVH issues. Usually, a fresh fluid/friction modifier change is sufficient to get things back to normal. The NVH issue became more apparent with the introduction of the Viper GKN Visco Lok differential in 2008. For 2008 – 2010, we lived with the standard 75W-140 fluid because it met all of our durability requirements and was less expensive than other lube alternatives. But we did have more of a friction modifier ‘loss of effectiveness’ issue with the Visco Lok as we got more experience with the new differential. We learned that on some cars, the Visco Lok would tend to make a howl/growl/grind noise when turning at low speed if the friction modifier was used up. So for 2013, we went with the special Castrol SAF-XJ 75W-140 synthetic developed by Castrol and GKN for the Visco Lok. This fluid has a different friction modifier and blend % already mixed for factory fill and Service. No added friction modifier is necessary. It is also recommended that the Castrol SAF-XJ be used for Service of 2008 – 2010 Vipers with the Visco Lok. I do not know if Castrol sells this product under their brand name, but I do know that it is available in a special ‘SRT’ bottle from Mopar. "
Transmission - Castrol Syntorq LT (has been discontinued though, so this one is going to be interesting in the future)
I know Dodge had a Service Bulletin to switch to Gear oil for the people that complained about NGR. So that's why I went Tremec fluid.. I will most likely be switching back to ATF because I liked the way the Trans felt with ATF better.I actually emailed Tremec a while back when the Castrol Syntorq was getting harder and harder to find to see what they recommended. They said something like Mobil 1 synthetic ATF was what was used in the vast majority of T56s. Admittedly the Viper is a little different than most in that it tends to be a much higher torque engine than others, but just another note to add to the conversation.
What are your thoughts on the non-synthetic ATF?
I don't do near the amount of transmissions he does but I've ran across a couple with the carbon the blockers shined up pretty good and the engagement teeth with sever wear.
T r a n n yIts a 96. Vin 33.. Not sure what the question was that was blocked out with ******
Assuming door sticker?
Tag on T r a n n y says Dextron III. I believe replacement is ATF+4T r a n n y
So the sticker would state Dexron III since 96 but check.
I bought 12x 1 quart bottles and changed mine (you don't need 12 quarts). Haven't driven it yet.
Get actually regular dex3 NOT the equivalent or compatible with Dex3. And don't do synthetic oil.
Gotcha. Lots of miss information out there!!! My lift is free this weekend and I am going to dump the Tremec fluid and going back to Dex III. Always felt the Trans shifted way better with ATF in there.
Actual Castrol dex3 (used F version if i remember right) (black bottle, I am not where the bottles are so I can't take a picture or the UPC code and can't find the email order). Found them for a good price and bought 12 online from Walmart. Even though I try to not buy stuff from Walmart.Gotcha. Lots of miss information out there!!!

Are you running the Valvoline? Dex / Merc?
Sorry can not confirm if that was it but i am 90% sure it is not. We discussed this on the other site with njsteve and you has posted in the thread.Assuming
Thats when I was running ATF+4 or Tremecs.
Is that a T-56 or a 6060?2006
