Replace ATF+4 with Amsoil ATF? Good idea??

I used Amsoil ATF in my grandmother's Town and Country van, and I didn't feel anything different.
That in mind, a UOA would probably best tell how well Amsoil ATF works versus Mopar ATF+4.

I don't know how much better the Amsoil would be other than the potential for a stronger additive package. Mopar ATF+4 is a group III base oil so its cold temp. properties are going to be very close to a group IV base oil regardless. In addition ATF+4 is becoming very easy to find at auto parts stores, and I have seen it on sale on a couple of occassions in the $3 range--not bad.
I am running Amsoil in my Jeep Liberty with no problems.
+4 is cheaper and easier to get. no shipping costs either. no need to risk the cc online.
go +4.
go +4.
I changed the MTX in my Neon to Amsoil ATF from Valvoline ATF+4 which replaced OEM. Amsoil is so far the far and away best choice. Much nicer cold weather shifting.
Friend replaced his Grand Caravans ATF+3 with Amsoil and got a 2 MPG bump in gas milage with better shifting in all weather extremes.
Great stuff.

If you are going to pay the big dollars for Amsoil, it will work wonderfully. But, if you want to spend the same dollars for a specific formulation just for the Mopar specs....buy Redline C+
I run the Redline with a Magnafine inline transmission filter. I am leaving the pan on and changing the inline filter every 30K. Will flush when the fluid starts to look oldish or when a UOA tells me to flush.

When I bought my Dodge Cummins it had the ATF+4 in the trany (G56) from factory. I noticed a big difference when I switched to Amsoil ATF. I now use Redline C+ATF, and while I find it doesn't shift as nicely as the Amsoil (it is very close), it has a much lower pour point, so I going to run it this winter and see how it performs. If I am unhappy at the end of the winter I am going back to Amsoil.
I like Redline c+ since I used in my my 2001 Dodge Dakota 45RFE transmission wich called for ATF+4.. It worked great and I have a UOA on this site for it in that application.....I know people who have used Amsoil in their 45RFE and they have not had any issues. Since I have used Redline's product and know it to be a perfect match for that application that is how I would go!!!
I wish I saw the mpg gains everyone else does from switching to synthetics, but I just don't. I switched my Dakota over to ATF+4 and Amsoil gear lube and have yet to see any mpg gains. Smoother shifting on cold mornings with the +4 but that was about it. Am I one of the few who doesn't see gains? 2 mpg would be a 10% bump for me, I would love to see it.

I've never been able to measure a fuel economy improvement from switching either.

Good idea? Yep
Is it necessary? Nope
What it comes down to is what brand do you want in your tranny, how often you want to service, and how much you want to spend?
Nothing wrong with sticking with name brand ATF+4 for regular service intervals. For
If you have brand loyalty, or want to use fluids elsewhere, then look for and use one of the univeral ATF's. Amsoil is a no brainer if you own several cars each with different OE specs, and you don't care to stock the shelf with 1/2 dozen different fluids.

I dont know if the +4 is the same as D4 but i ran that in my Tacos tranny and now i have a few qrts of Amsoil Universal ATF and so far so good.
I have the 42re in my 4.0 running 31's and towing a small 17ft'r on the weekends during the summer. Saw a ton of wheeling this season, ATF+4 held up well.
I installed one of those universal drain plug kits in the tranny pan toward the passenger side so I can do partial drains after the boat season. By the way I have been using the Wally World Super Tech brand atf+4 the whole time.
I tried the Mopar stuff once (full flush), didn't notice anything different.
Just stay on top of change intervals and your 42 will last a long time.

Redline D4 has frictional characteristics similar to Dexron III. It is not like Chrysler +4.
However, Redline C+ is like Chrysler +4.
