They can be adjusted ! you want a nice tight shifts but not slam shifts.i know the 400 is mechanical so nothing i can do will help the shifts? this doesnt seem right? i know shift kits provide more fluid in most cases to get more firm shifts but i hear they are not always the best this is all i was asking. thanks nick.
Nope, diesels won't generate enough vacuum to operate a vacuum modulator on a transmission.so there is no way to make it work properly? because it wont be able to shift properly. right now with my 6.2 in it it feels sluggish could that be because the 6.2 doesnt generate enough vaccumm thanks for your help.
anyone heard of a cable operated modulator for the shifting problems that turbos10 was talking about? i imagine that it would work because it states it can be used on diesels. i imagine that once the motor gets a certain load on it will allow it to shift properly? thanks for your help.
That's the ticket for diesel + TH400.sorry what i meant was not the one that comes with the p30 van but one from patc? it sells for like 120
It doesn't work that way. A vacuum pump is producing about the same vacuum all the time. The vacuum a NA gasser generates is inversely proportional to engine load. High load = WOT = low vacuum. Light load = mostly closed throttle = high vacuum.would it be possible to run a line from the vacuum pump to the brakes and the vaccumm modulator on the trans in order to gain proper shifts? thanks for everything nick.
