Be aware that a trans tune will put more stress on the driveline components. Everything from the crankshaft to the wheel bearings.

When Chevy tuned the car they not only looked at performance, but longevity vs. cost. How many hours of super-computer time did Chevy spend to determine the trade-off between more expensive parts and average life expectancy? So much that they bought and maintain their own super-computer. And enough that they met a certain price-point, that, although more expensive than a Malibu, much less expensive than a Ferrari.

Sure, everyone who sells tunes will tell you it will last longer, because there is less slippage, but that is false. A slam into second can destroy parts other than the bands and clutches.

To me, it's just a cost. To you...

Which is what led me to buy manuals. Every time I leave the line, every shift I make, I control the slippage and the throttle. Here, now, real time, real circumstances.
You make the choice, not some computer imagining.

I have a lifetime of experience destroying tools.
And, yes, your car is a tool.

Sometimes it is worth it, other times, not so much.
Daily driver, leave it alone. Part-time fun machine, go for it.
