Talking Hard Shifting Tranny

I just got a 2002 F-150 Harley Davidson truck, pretty much stock. I have noticed that under "normal" driving the transmission is somewhat smooth going through the gears but when I really jump on it, either from a standing stop or while I am already moving, it shifts extreme hard, especially from 2 -> 3.

Has anyone else experienced these issue? Does anyone have any suggestions? Solenoids maybe? Something else?

Thanks

It sounds like the previous owner put a modified valve body in.

What is the advantage/dis-advantages to putting a modified valve body into the transmission? I would think that one would want the shift to be smooth while they are accelerating, especially with the power that this truck has.

Sloppy shifts are for the masses. The faster the shift the less friction on the plates. Less heat, extends life of tranny. Not to mention chirping gears is fun.

Other than better performance, a modified VB will reduce wear on the tranny clutches.

Sounds like you have a Factory Tech VB (FTVB), or maybe a LFPVB, on your tranny.

Add a higher stall torque converter and you'll have a nice tranny setup for racing!

Smile Harley Tranny Problems

Hey,
I had a problem with my Harley between 2nd & 3rd and just installed the Sonnax modulator.
We also found 2 broken springs in the valve body.
Truck is running "Great" for now.
Hope this helped.
Mike
