  • I have a jdm r31 skyline rd28, plate says it has l4n71b trans, no real problems with it jus doin a service, everything looks same apart from the low band dosen't seem to be adjustable instead of the rod and lock nut protruding it has quite a fat solid looking machined steel piece with circlips holding maybe the rod, could this maybe be a type of auto adjustment?

  • I have a question. I have a 93 miata that has this transmission. Where can I get the solenoids for this transmission? Everywhere I look they don't have them.

  • Just like to thank you for posting this video this overdive thing has been doing my head in for so long at least now I have some where to start at resolving my OD working or not working intermittently.

  • great video mate, ive been trying to figure out why my overdrive doesn't work. I thought it was the instrument panel. I got it working sometimes by playing with the terminals on the bottom plug but now that doesn't work. I'm thinking its the vacuum modulator. I took the hose off the modulator but no kickback and it winds out the gears now but makes a funny noise when idling. I believe it may be a vacuum problem because I would hear it clicking in second and wouldn't change to third unless I accelerated hard. But i'll check the wiring also.
