modulator is round and located on the drivers side of the transmission. modulator unscrews from the transmission if it is a 700 R4 It unbolts with 2 7/16 bolts if it is a turbo 350 Unplug the vaccum line remove the modulator replace with new modulator hook up new vaccuum line

That transmission is COMPUTER CONTROLLED and does NOT have a modulator valve. If you are having transmission problems then you need to have the transmission scanned with an OBDII engine scanner to see what is going on.
