    Looking for stock 7.3 tune for 1999 auto F250/350

    I used the tune on the forum here to check against mine but not sure if it's stock. Having very early TCC shift points and firm shifts due to TCC staying on at low speed. Trans line pressure is up higher than normal by 30 to 40 psi. After rebuild customer is concerned of hard shifts. Want to make sure the Tune is not effecting trans operation.
