Amsoil synthetic tranny fluid
I'm due for a tranny flush and am looking to go with Amsoil for my 4R100. It feels like it has been slipping a little. I don't think there is a problem with the tranny because the same symptoms cleared up after my last flush. At least I hope. It's been about 30K miles, but I do some heavy towing probably 40% of the time. The truck just turned 70K. I know the manual says not to use dual usage fluid, but Amsoil claims that with there fluid there is not a problem. I've heard a few opinions, most of them good about using this fluid. The tranny doesn't seem to slip under full throttle, but cruising around town it feels like it slips a little and sometimes doesn't want to shift gears like normal. I'd rather spend $300-350 for the synthetic fluid and do it myself than give Ford my money anymore and have them do the flush for the same price. Any advice? And has anybody switched over to Amsoil?

i think amsoil make some syn fluid called "torque shift" which is not dual usage... as for your tranny... i hope you have a BIG cooler added to your system and a real tranny temp gauge..!
i haven't switched over yet, but i was on the amsoil site last night pricing out that syn fluid..!

Here's what I found last night. Their site lists 2.5 gallons at $160. Worth it considering the stress I put on it.

JJfiveoh, you don't want that Amsoil synthetic ATF as it is dual rated. Get the Torque-Shift as Jonnhy8 said. It is only a couple dollars more per 2.5 gallons but is meant for high torque applications: https://www.amsoil.com/storefront/atd.aspx
I just purchased it last week, but have not had a chance to put it in. I was told in another thread about this stuff and my Amsoil rep confirmed. I will be putting the Sonnax kit in with the Torque shift and the TruCool cooler in the next couple weeks and will let you know. It should only run about $200. I also purchased a little extra so I can change my transfer case out at the same time.

Strokin uses the Torq-Shift and loves it. I'm suprised he hasn't been on here yet recommending the switch. I've heard good things about it, but have yet to hear any negatives other than the cost.

I have a question for everyone. If u keep your tranny fluid cool enough all the time(aux cooler) and clean enough(external bypass filter) why should one spend twice(or more) the price for syn over dino? The only advantage of syn from what i understand is it's slightly superior thermal conductivity properties. I put in dino so far for about$7/gallon and the Amsoil Syn is $35/gal or so.
