[QUOTE="jim beam"] ok, if filter clogging is an issue, then it's good to change them. this should have been revealed in failure analysis though, not be the result of what is, with respect, a pretty much random maintenance schedule. in an ideal world, you'd have had the manufacturer work with you to figure this stuff out, not just gouge you for new transmissions.[/QUOTE] I know what you're saying, but we don't live in an ideal world <g>. Doing what I did was the logical step towards solving the problem(s), with Allison's labour rate of 5.00 an hour it doesn't take long to waste a grand when looking for the answer.
