What's the best fluid for my 03 Allison ??
Hi all, Can I get your opinion and ideas on what is the BEST, not least expensive, fluid I should use for a filter/fluid service. I can't seem to find a solid answer to wheather to use Dex III , Dex VI or Transynd in my 03 Allison. I have got a lot of conflicting answers to this especially from GM dealers. thanks

I stand with royal purple
i think its amazing, having use it in both manual and automatic transmissions.
runs cooler, shifts smoother, and overall- keeps the trans cleaner than whatever the manufacture calls for
so yeah, i say invest in that stuff.
my jeep, my chevy, and my friend's mustang, all love it

It gets a little more complicated than that when you are 2500 miles away from home pulling a 13K pound 5th wheel and you need a tranny overhaul at the tune of $4500. Thanks for your help so I think I will use what all the Allison dealers recomend.
Have a great day and thanks again.

daaaaaaaaaaamn thats a lotta gas and groceries they just robed you of.......
they had better have taged on a kick ass warranty for that price.
and if they did, then totally get what they tell you to get for oil... preserve the warranty

oh thank god
well either way with regular changes and attention to fluid level and quality, it should be fine no matter what.
i still say royal P though. especially for towing, because it runs cooler. heat kills auto transmissions
