T-35 tranny question

["Jay" <jciampi@xxxxxxxx>]

My 66 American/232  has a T-35 tranny, I guess and it has a rather harsh 
downshift from 3-1 when coming to a stop. It is harsh enough to cause a 
clunking noise (not the driveshaft as that has all been replaced, bushings 
and all). I see in the TSM that the  tranny has a modulator valve and 
according to a friend who USED TO work on ATs, the modulator can cause this 
symptom. The TSM isn't very specific, but it looks like the modulator is 
INTERNAL (unlike my old Ford 390 of years ago). If so, I guess that's a job 
for a transmission shop.  I had to replace the Ford's modulator several 
times due to leaks in the diaphragm and blowing smoke all over the place. I 
finally got one that held up.
