Allison 5sp: Filter change

[dirtydmax]

Well it's time.First filter and fluid change since build and have a question.Should I change both spin on and internal filter's or will just the spin on be ok.I am in the middle of the change and thought id better find out before I fill and have to do it twice,Also Thanks to everyone on DD for all the advice you shared during my build,This trans is BAD A$$,no more limpin!

My builder said the spin on would be enough when I had mine built and asked that very question, said just the spin on @ 500mi

Glad ya like the new trans:thumb:
