Hard shifts on automatic?

So I just got a new Lund tune on my 14' GT premium automatic. I don't any mods yet just a drop in k&n filter. I drove away from the shop after the tune and I feel like it has more power but the shifts are really hard. I'm not sure if that's normal? Or if it's going to hurt the trans? If I'm really easy on it it's ok but if I punch it a little the car really jerks as it shifts. Any advice?

No it won't hurt anything. Just request a different tune with softer shifts if you prefer.

Harder shifts are actually better for the transmission.

So I notice it the most if I try a launch at almost full throttle. It chirps the tires after every gear. Is that good? Bad? Indifferent?

Ok haven't had a muscle car in a long time and my last one was a 74' maverick with 600 hp so it's a little different.

And I'm honestly not sure how a harder shift is better for the transmission?

Less slippage of the clutches makes them last longer.

Ok so I drove this thing some more with the tune and maybe I love it!!! I used the track apps and tried my 0-60 which my previous best was 4.9s. This time was completely different... 4.6s and that was my first try!!! I can't believe it made that much of a difference.

Like GMB said, less slippage of the clutches. That means that the clutches will last longer and there is less heat created which can increase your transmissions life GREATLY.
There can be increased wear on other components due to the hard shifting though, mainly motor and transmission mounts but also u-joints and tires can be added to the list.
I'd much rather replace all of those items TWICE rather than replace the expensive transmission once.

The soft shifting does not hurt the transmission unless maybe you are constantly shifting up like in heavy traffic.


I wish my auto shifted firm like that though. I can't believe Ford didn't build a firm shift into the "sport" mode. $350 for firm shifts is ridiculous. It used to be achieved with a $20 shift kit back in the day.

Nothing is healthyier than a hard shifting automatic. Like the others said slippage equals heat, and heat is your automatics nemisis. I think clutch material seperates from the packs at around 290 degrees Fahrenheit. I had my AODE beefed up years ago and it will cheep into second and third. It's neck snapping how hard it shifts, but that's what you want.

Yep. B&M shift kits (a plate, a drill bit, and a pan gasket) was what it took to firm up the transmission. Plus, the labor to install if you were not savy in the dropping of the shift valve housing of your transmission.

That's exactly what I have, the b&m shift improver, with a firbanks shift kit. He also put the red eagle police interceptor clutches in.

Just have Lund soften your shifts a little for you. Real easy.

My VMP tune shifts perfect. Then again, Justin owns and tunes his own blown auto 5.0.
