Thanks for the help guys. I feel confident that I won't damage anything now. As for the benefits of synthetic ATF, that's a tough one. There is no question that Amsoil ATF outperforms conventional oils and can lower transmission temps considerably. But as with most upgrades, is it worth the cost? For me it is, for others maybe not. I always put 87 gas in my truck; some pay $0.20 more per gallon for 92 (that's approx. $200 per year more than I pay). Generally I go with what I know. I've owned my own vehicles since '87 and have been using Amsoil products since '89. I've NEVER broken down, never had to have an engine rebuilt, never had a trans fail, never overheated, never had brake problems, the list goes on. I don't put this down to luck. I follow a strict maintenance program, part of which is using quality products. I flush my brake fluid EVERY year ($10), I flush my cooling system EVERY year ($30) etc, I inspect my brake pads every month, I check tire pressure every week ... I'm boring you I know, BUT IT WORKS.
If you think about it, generic ATF costs around $3.00/qt. Assuming that you use 18 qts, that's still $54. If you go to one of those "leave off the oil cap" fast lube places, they'll charge $80 - $90 to flush and fill the transmission system. $118 (18 qts) isn't looking so bad now.
A slight detour ... the March/April issue of Truck Trend claims that the F-150's trans heats up very quickly, and this fell under the "What's Not" category (page 22). I'm not sure how they determined this, as I doubt that the test vehicles came with a trans temp gauge.
Anyway, sorry to go on. As I've mentioned before, I don't sell Amsoil, I'm not even a "preferred customer", I'm just a VERY happy end-user.
I mentioned in another post that I get caught in traffic a lot, and it's always hot over here, so I consider my application to be "severe duty".
Thanks.
