    Trans longevity really comes down to how it was built and how you drive.

    I can kill a fully built trans in under 2,000 miles when driven properly. Or I could have a stocker go well past 186K miles when driven for that purpose.
    I drink..so consider that when reading my posts.

    Prove me wrong.
    Irridium spark plugs last 100k mi and work just as well as copper. Copper is a waste on N/A and only lasts 15k mi. Don't use Platinum.
    Use 195* tstat unless you can thoroughly explain why not; 99.9% don't need a lower temp.
    Almost any oil filter, ever, is of higher quality than ACDelco. Spend $6+.

    which bumps up the line pressure.

    Doesn't physically change the springs in the accumulator.

    That doesn't do a lot. A shift kit will help out a lot on the longevity of your trans.

    They should have put 2.93's in it or you would have some weird shifting issues.
