I just talked to mike L. his recomendation is 50K max on the internal filter. so for me since i'm only at 25K since he did the trans I can just change the fluid ( i'm going to amsoil torq drive )then when I get to 50K on the trans drop the pan and do the internal filter and fluid.

I change my trans oil & filter every 30K. The dealer said I should change the internal screen at each change. I don't think it'll hurt anything, but it is an extra expense. If I ever switch to a deep pan and syn, I'll probably just change the spin on and replace lost fluid.

I have 265,000 miles on my truck and have done nothing but change the external filter and had the trans flushed by the dealer 4 or 5 times. I just find it hard to swallow that the internal filter should not be changed at some point.
That said, with all the towing and hard miles my truck has got on it I am going to change the internal filter and fluid this week.
I said that about 3 weeks ago and haven't done it yet.
I was looking at the Allison links provided herein and the fluid is said to have to be Dextron III for the 1000 series trans. My son said the 05 and later trucks have Dextron VI listed as the fluid in the owners manual.
Is the Allison data just not updated or is it OK to use Dextron VI?

That is what I would have thought but wanted to be sure. Thanks.

I found that Valvoline makes the Dextron III fluid but it is Dextron-Mercon. It is compatible with all the Dextron requirements and the Ford requirements. It is half the price of the Dextron VI fluid.
