Only changed the trans fluid once in 30 years on my 65
'Changed once in 30 years' (30 years of ownership i assume).. so you could have changed it 30 years ago or 15 years ago or 1 year ago..
I get the only 6k miles argument but the fluid could also deteriorate over time so if it was 30 years ago it wouldnt hurt to change it... it might cause slight temporary discomfort in the wallet but its only passing.
