Hey Bob. I actually tried that and it seemed to work but I didn't get to drive the car that much before I put it away for winter. I was just concerned about the color of the trans fluid, being reddish brown, and if it is no longer any good. I have read that the color can change over time without the actual fluid being bad. Thanks for the tip.
I think changing the fluid certainly can't hurt, and it will give you peace of mind. When I change mine, I might consider adding this: LUBEGARD Automatic Transmission Fluid Protectant
A little insight into the history of the company: International Lubricants Inc. (ILI) - Makers of LUBEGARD
Since 1984, International Lubricants, Inc. has been a leader in researching, developing, and manufacturing patented high-performing ester-based synthetic lubricants and related products for automotive, industrial, marine and agricultural applications. It started here, during the preliminary development of the company’s proprietary LXE Technology, that International Lubricants Inc. took the opportunity to manufacture products that were friendlier to the environment, benign in their affect on users, and superior at resolving many common fluid-related difficulties.

Dr. Phil Landis, former head of Mobil Oil Applied Lubrication Research Group, became an automotive industry tribology pioneer through his formulation of the LXE, Liquid Wax Ester, Technology as a direct molecular replacement for sperm whale oil.
Why sperm whale oil?
Sperm whale oil and its derivatives were used as additives in virtually all automotive lubricants. The products were so effective that vehicles’ fluids were generally never changed, and systems like the transmission lasted the life of the car. Some 30 million pounds of sperm whale oil were used every year in lubricants alone. To supply the demand, hundreds of thousands of whales were harvested bringing that species to the brink of extinction.
The sperm whale was named for the valuable spermaceti oil (wax) that this whale produces in the spermaceti organ (located in its head). It has the largest brain of any animal, weighing about 20 pounds (9 kg)! The most famous sperm whale still to this day is from the fictional novel Moby Dick and was written by Herman Melville in 1851.
In 1972, the Endangered Species Act outlawed the killing of whales and the use of materials derived from those animals. For years, in engine oils, the automotive industry relied on other animal based products such as tallow or lard. For complex systems such as transmissions, these substitutes proved to be inadequate, leading to poor overall drive train performance, premature drive train failure and failure due to heat. For instance, automatic transmission failures went from less than a million units in 1972 to over eight million units a year by 1975, due to the loss of sperm whale oil additives. According to the Automatic Transmission Rebuilders Association of Ventura, Calif., today, there are over 11 million automatic transmission failures per year (and nearly nine out of ten) are caused by the degradation of automatic transmission fluid due to heat. Heat promotes the oxidation of transmission fluid, and that compromises its performance and accelerates wear on the internal components of automatic transmissions.
