What makes the 3 rd gear shift in a reverse manual 727 shift in so hard? what is the modification needed to get that positive drop in rpm? It seems my 3rd gear has gone away from what it once was. this is an 11 second race car not street driven with a 4600 converter. Will a loose and slipping converter soften the shift?

The converter plays a big part in shift firmness. The looser the converter, or the smaller the converter the less shock it can transmit to the motor to drag it down quickly.

ft pump modification [oil hole] teflon rings clutch pac at 60 thou 12 springs in the drum and a griner valve body! mine hits high gear so hard sounds like sombody hit the side of my car with a snowball !!!POW !! even after 7yrs 6000miles had it iout last nite could not keeep the glove box closed
