Test the each TVS with a direct vacuum. The EFE tvs should allow vacuum when the engine is cold and block the vacuum when the engine is warm. Vice versa for the EGR TVS. Just make sure the EGR is on a timed vac port. Your engine will run like crap if the EGR is open at idle. A bad diaphram is also a good place to look for a vac leak.

H 400 and TH 350 can use the SAME modulator. Keep in mind that adjusting the modulator is NOT the proper way to change the shift points. The modulator affects shift firmness, and the shift timing as a "side effect". Modifying the modulator raises the pressures inside the transmission and makes life tougher for the rubber seals and the pump.
