I am aware of three detents on the sandwich plate. Two on the driver's and one on the top right.

Can someone tell me which one is for 3rd gear?  The top right one seems to be 1st and second.

This should help you out

This is for a four speed, but it is the same layout for the five speed transmission. Fifth is on the reverse fork rod.

I replaced all mine in 2012.made the select feel so much better and clicky a bit like new, if you know what i mean.

Courtesy nissan list them now as NLA.

What are the options for replacement now that they are NLA from Nissan?  Anyone find a supplier?

Their is a trick so you can regain some of the tension on the old spring. I did it on ine and it worked well.

Cut a section off the spring and fill behind the spring with a couple of washers. Best to do this with some old springs from another transmission. If you cut too much and have to use too many washers, the spring will bind and jam the selector.

The theory: A coiled spring is simply spring rod rolled into a coil. Shorten is and it will become stiffer. A bit like holding a plastic ruler over the edge of a table. Move it out10 inches and it will be flexable and you came move it up and down easily. Move the ruler in to 5 inches and you will not be able to move it as much. It will be stiffer.

I just google the parts again to see it they can be purchased anywhere. The original part are NLA. Looks like its time to hunt for and alternative supply.

Here is a thread about them a couple of years back. Just need read past the OP uncertainty.

These detent spring are always overlooked. I don't think any workshops replace them. Such a pitty because it can make a big difference in shifter quality.

Thanks for great picture! Perfect. My issue was similar. It would pop out of third when I lifted to brake at 7400rpm.

My planned solution - put a ball bearing on top of the spring and use washers to position the bolt. Too much tension and you can't get it in gear. Too little and it pops out. A Goldilocks situation.....
