" From: "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. how's the vac line? when i got my '67 marlin/232, it wouldn't shift into high at all because the line [actually tranny fitting] was broken, wedging it into 'full throttle kickdown' mode. it would shift 1-2 manually via d1/d2. ________________________________________________________________________ Andrew Hay the genius nature internet rambler is to see what all have seen adh@xxxxxxxxxxxxxxxxx and think what none thought
