Yeah, the whole "no dipstick" aspect of the 4L30E has been it's greatest complaint for the owners of the various makes it's been installed in. Once, I came across mention of a "dipstick tube" part and had hoped to see if such a thing would bolt up to the models without a tube. Never could get more info than the vague snippet I stumbled on.

If the Aisin 5-speed install goes nicely in the rally VX we're building then I may just need to convert the IronMan too.
