I could agree with you in not having to change the trans oil but there are still some things short of changing it that could be done. Remove the level plug and verify the correct level. Remove the drain plug and install a magnetic if not already done. Drain some of the fluid out and inspect for bronze dust, water, and metal chips. Feel the oil with your fingers for grit and viscocity. If it is clean put it back in or top off with a little fresh oil (A little fresh oil shouldn't affect the seals). On the manual trans the oil not only is for the transmission but also the final drive. Inspect the exterior of the trans and final drive for any evidence of leakage by the seals or gaskets, a little seems to be normal on most Deloreans, especially where the case splits.
