Never seen hard proof that frequent changes or boutique fluid ensures auto transmission life, but likely most here are confident it does. When you look at the expense and inconvenience of a transmission failure, and balance this with the relative pittance of overkill maintenance, penny pinching might be foolish.
I've had a mix of manual and auto transmission cars and have generally followed an overkill schedule on the auto trans cars and have had mostly good service. I'm running Transynd in my 2003 Silverado and doing full replacement (Hoot method) at 25K intervals. It currently has 45K miles on it. My 2000 Concorde got fluid and filter at 60K (bought it used) and several dip stick pump outs at 120K miles. It currently has 140K miles.
I suppose transmission expense paranoia drives my fluid regimen, even though I would rebuild myself if one failed. The job would be difficult to remove without a lift and a transmission jack.
Anyone else driven to overkill maintenance due to fear of auto transmission replacement or rebuild expense? What overkill steps do you take?
