Mike7447 Posted October 8, 2024 Report Share Posted October 8, 2024 I dropped the VB today in order to do the required mods to it for better shifting. That required I remove the vacuum modulator and one of the two solenoids that interferes with the VB removal. I assumed that the hose that was coming out of the vacuum modulator was removable, so I tugged and pulled on it to the point that the hose started to tear. Idk if the hose is actually part of the stinkin thing, but it’s a mess now. Where do we get replacement parts for the trans? I called two of the city transmission parts suppliers and got told that the part was unobtaninium. This can’t be right???? Link to comment Share on other sites More sharing options...

Even the manual boxes have a bearing that is not available anymore. I have never massed with an auto, so I'm no help there. Did you check the parts manual over at starquestgarage? Might show if that vac line is separate. Link to comment Share on other sites More sharing options...
BuGG Posted October 9, 2024 Report Share Posted October 9, 2024 The hose is not part of the vac modulator. It has a port for the hose to connect. Link to comment Share on other sites More sharing options...

All I can think of is that some previous owner glued the l shaped hose into the damn thing. I couldn’t dig the remaining hose bits out of the modulator.

Might show if that vac line is separate. When you google vacuum modulator for LN471b trans, they come up. As a replacement part for a Mazda. It’s a vacuum modulator that looks exactly like the one I have only w/o the L shaped vacuum hose seized up inside it. It’ll be here Friday. I’ll do the VB mods as per Scott’s instructions, and put that part back together. I want to get the engine and that heavy pig of a transmission bolted together and reinstalled in the car. I tell ya, I have messed w/quite a few auto trans before, w/a GM 4L80 being the heaviest, but this Mitsubishi trans is way heavier than that. Given that a GM 4l60 has a 3.06 first gear, versus the 2.42 first gear in the mitsu, all while probably being 100 lbs lighter has me seriously considering trying to adapt one to the engine at some point in the future. 1 Link to comment Share on other sites More sharing options...
BuGG Posted October 10, 2024 Report Share Posted October 10, 2024 (edited) Now this is not from personal experience but I heard that any vac modulator you try should say for turbo engines. This trans was put in N/A cars as well so they made two versions of vac advances. If yours does not work try this one. http://www.transmissionpartsusa.com/Nissan_L3N71B_L4N71B_Turbo_modulator_1971_on_p/820-000082885.htm Edited October 10, 2024 by BuGG Link to comment Share on other sites More sharing options...
