could a modulator overheat or damage a transmission if its bad? what does a broken vacuum hose do to the transmission?
HI Anything is possible but not usually A bad modulator will cause it to hang up in gear and not shift until way up in the RPM's I'd replace the hose and the modulator valve and go from there and if there is more problems then maybe try changing the fluid and filter in the tranny, If the problem still persists then I'd go to a transmission shop and have them check it out good luck tim
verify the fluid point! this is finished with the engine working and in park or impartial, if the dipstick would not specify which your vendors instruction manual will. no rely if this is packed with fluid the take carry of packs are slipping and you will ought to have the tyranny rebuilt or replaced. (while checking the fluid point pay interest to the colour and scent of the fluid, dark and burnt smelling fluid additionally potential that the tyranny is slipping)
indirectly i suppose that it could. if the modulator causes the transmission not to shift and remains in a gear for a while it could cause a warmer that normal running condition. a broken vacuum line causes a delayed shift and the engine will run hotter due to a lean run situation. this heat transferred to the radiator could cause the trans to run warmer still.
