i just finished rebuilding my 700r4 with just about all the goodies for a 700hp handling unit, 5 pinion planet gears, trans go shift kit, harden drum corvette servos, 13 vane pump 8 clutch pack 3/4. when im driving the car it starts out in 2nd gear but i can manualy downshift it to first and when the tranny warms up it makes a weird whine from the front of the tranny when the car is at abut 900-1000 rpm. please help i dont know what to do anymore i ran out of ideas to fix the problem

 

Double check the TV cable adjustment. 13 vane pumps are a bit noisey as compared to a 10 vane.

 

will it hurt if i go back to a 10 vane pump will it be sufficent with all the mods
