727 doesn't shift into second gear like it should

If I were you I would take it out or take it to the builder and let him do the work. You paid for the work and you should have a good working trans.


Yep, my trans sequels the tires on the 1--2 shift. sequels them loud shifting at 6,500. You take off nicely and then around 45 mph light the tires up in 2nd by banging it in to 2nd gear :D
