baccaruda Posted July 15, 2004 Share Posted July 15, 2004 hmm. some center differentials use a switch-operated vacuum mechanism to lock or unlock. Quote Link to comment Share on other sites More sharing options...

Your question doesn't really make any sense. Are you referring to the tranny>? The switch? the vacuum switching mechanism (solenoid pack)? The solenoid packs are the same for the pushbutton 5 speed and the FT4WD 5 speed difflock. Quote Link to comment Share on other sites More sharing options...

MilesFox Posted July 15, 2004 Share Posted July 15, 2004 the pushbutton 4wd and the center diff lock use the same mechanism. i put an xt full time tranny in my turbo pushbutton 5spd, and my existing 4wd button and all the vac lines worked the diff lock mechanism the same. you can take a car with diff lock and put a pushbutton tranny in there and the diff lock switch will be your 4wd. when a full time diff is locked, it is the same thing as a pushbutton(part time) tranny engaged into 4wd Quote Link to comment Share on other sites More sharing options...
suberdave Posted July 15, 2004 Author Share Posted July 15, 2004 ok so is what i am hearing is that they are the same? i just bought a 88 gl with vacuume 4wd, but the guy through in a different trans, he said it was a AWD with center diff lock (and he gave me the switch also). if i put that in my gl, what is going to be the difference, they look the same. i know looks arnt everything, but i have never done anything with a AWD trany. will it be AWD, if so what is the point of the vacuume soloniod? and what dose the diff lock do? thanks -=suberdave=- Quote Link to comment Share on other sites More sharing options...
mcbrat Posted July 15, 2004 Share Posted July 15, 2004 for a pushbutton 4WD, when you push the button, you go from 2WD -> 4WD with no center diff, so you are locked front to back for the full time 4WD trans, when you hit the diff lock button you go from 4WD with open center diff -> 4WD locked front to back. (same as pushbutton) The difference is the center diff. the FT4WD tranny doesn't have a 2WD option) Quote Link to comment Share on other sites More sharing options...
