feelings on automatic fluid filter change....

My 88 n/a auto is registered/inspected and just about ready for DD status. Car has a rebuilt auto with less than 12K miles on it -but- it was rebuilt about 10 years ago and sat for nearly 8 maybe more. Car shifts pretty good but has a slight flutter in the 1-2 shift. Otherwise fluid is brand new looking, smelling and everything else is fine.

My opinions of 'murican cars with high mileage autos is to never, ever change the fluid. Something in that dark sludgy metallic mix holds it all together and I have seen many a domestic auto go south immediately after a fluid & filter change. I have heard (on here maybe?) the clutches dry out when they sit for years and it can shorten the auto lifespan.

So should I? Will it be the nail in the coffin or do they respond well to this? I've got a kit and a box of Redline ready to go. I was also going to add a tranny cooler too, heat is the enemy.




and yes, I will be doing a manual swap eventually. Just have to hook up with Gardner and pick up some 71C's when I have a day off (like never). And finding a manual 2+2 driveshaft is like finding a fucking unicorn horn .......for whatever bizarre reasons I have yet to understand
