Redline D6 VS Amsoil ATF

[Env1ous]

Hi all,

Im taking a look at the options from redline and amsoil for my transmission. I have a 2013 F150 Ecoboost. This will be my second pan drop and fill and im at 84k miles.
What does everyone recommend? I do drive fairly hard and I am tuned so I am pushing more power than at stock levels. I do want to keep this truck as long as possible!

Having used both Redline and Amsoil ATF's if you want an ATF that is great under load and heat I would choose the Amsoil it's honestly the toughest ATF I have seen.
I've used it in too many applications not to see the benefits. Even after towing for extended mileage on the ATF it still comes out nice and red.

I used both and they both excellent fluids. I usually get Amsoil since it's easier to get, just a phone call away to my dealer. I have to order Redline from Amazon as we have no local dealers and sometimes I get a message can't ship to Hawaii and sometimes not.

Why would you not use Mercon LV? With a flash point of 421F and a pour point of -54F what's not to love? Isn't this what Ford recommends for your trans? Surely it's not more expensive than either Redline or Amsoil. Very robust fluid IMHO.

 

[Gebo]

Amsoil simply because it it easier to get.

If you are in a cold climate id choose Redline simply because of the Brookfield Viscosity. Redline stays nice and thin at low temps compared to amsoil.
Both tests at -40C. Redline-4500 Amsoil-7676.

Redline for sure! you can talk to a tech for information, these days Amsoil is moot about ALL of their products. i formerly used Amsoil products but no more. i got better delivered pricing from E-bay than others. shop around + use various searches as favorites are evident from the big G

Explain the "moot about all their products" they release as much data and more in some cases that other blenders/manufacturers.

OP you can'r expect everyone to know every thing about your application, you need to tell us the spec oil. I do favor redline products in most cases, however the Amsoil atf is very good as well. There have been uoa's on Amsoil's atf that showed no shear after long usage, and you can expect that from Redline as well. For gears and transmsions their products are fairly equal. But we need to know the spec oil to see the correct version. Spec oil tells us viscosity range for proper operation of that vehicle. Use the correct fluid viscosty, either would be a great choice.

The spec oil for the 6r80 transmission and most fords after 2008 is Mercon LV. Sorry about that!

Thanks everyone for the replies. I did just buy my Amsoil PC subscription again. I think I am going to go with Amsoil for the trans!
Just looking for something to keep my trans happy!

They say Mercon 4, but that doesn't sound right, what does your owners manual say? Mercon 5?

 

[burla]

ok cool, good choice.

Also, when it comes to engine oil Amsoil ss is a great choice for the eco boost, made for di turbo with great moly level which is a known lspi quencher. On the other hand, until redline makes a di friendly oil, not a good choise at all for the engine oil. Peace, Burla

Thank you!!

The longest run I had was in my Santa Fe with no serviceable filter. It would turn the OE Diamond SP-III from Hyundai dark in about 30K miles (50K KM), I flushed and refilled with the Amsoil ATF and found I could easily go 100K KM (60K miles) and it would still be like new coming out.

The hardest application I used it in is my uncles Ram 2500 and he tows regularly with it on the highway. Comes out only dark red even well after the severe duty interval in the manual instead of almost black like the OEM fluid.

I did see some stuff about the Mercon LV. It is not a lifetime fluid. I see in about 50k miles (mine was burnt when I swapped it out the first time) and with that much power/heat I would like something with a little more protection. I am not easy on my vehicles. I use them for fun and DD them. The longer they last the better. Odd question, is both Amsoil ATF red in color?

When I do the fluid swap I am going to drop the pan and do the filter and add an upgraded trans cooler as well.

 

[StevieC]

Both Amsoil Multi-Vehicle ATF fluid is red in colour.

The low viscosity formula comes in the blue-capped bottles.
The regular viscosity (thicker) for traditional transmissions comes in the red-capped bottles.

Unless you are towing really heavy loads for prolonged periods of time I wouldn't worry about the cooler, the fluid will be enough.

That makes sense! Thank you
I am adding the cooler because some of these climbs here in CO in the mountains are crazy. I may be picking up some toys in the future. I know the 6r80 has a thermostat that opens at 190 but If I can keep the temp as close to that as possible I will be happy. Some days just cruising on the highway I see 215-220

 

[StevieC]

Yeah I would want to keep the fluid temperatures under 200F as much as possible. I know that they run higher temperatures today but it has always bugged me. I guess because of all the failed Chrysler transmissions in the 1990's we rebuilt and then would install external coolers on to keep them from failing again because the cooler in the radiator was too small and would often plug up with clutch debris in the oil.

When I bought my 08 ram the first thing I did for the 545rfe was a larger external cooler lol!

Sometimes on a trip in the mountains I go from 5500" all the way up to 11000" so I rather be safe than sorry. The upgraded cooler is from the Saudi Arabia spec raptor and it is $100. And I feel like the Amsoil will help more too.
