Recently my shifts feel quicker but softer than before. Is that a sign of impending death? I have been running upped line pressure. Is it bad to run higher line pressure? What would you reccomend to keep mine lasting as long as possible? How bad is it to have too much fluid? What trans would you reccomend for my setup? (475 crank ft/lbs 4wd ecsb 4.56's 35's driven moderately w/ 10% fun time).

 

eventually they will get like that but then again trucks have a mind of their own. Mine doesnt shift exactly the same all the time. corvette servo + shift kit is supposed to make it last longer. Having too much trans fluid is like having too much oil in your motor, you can burn it up.
