Changed transmission fluid. So easy using the Hayden 397 fitting. Jet.com pricing for Supertech Dex VI is cheaper than walmart.

What method did you use. I'm not familiar with the fitting you mentioned. I have 105k miles and need to service my tranny

This is the last time I will see these. When they come back, they will be hydrodipped in black walnut
