5 speed swap

[Dave WM]

Neutral/4th gear/reverse light. Its detailed in the FSM, the only one you need is the reverse light switch. I am pretty sure the neutral is for the interlock mech that keeps the car from starting unless everyone is seated and buckled up. I got tired of reading it. the 4th gear switch maybe something with the ign advance. did not see it on 1st pass of the FSM. I did not see it in my online copy but was in the hard copy book I have.

Nobody wants to look at the picture?  It's a big one.  Or just set their meter up to beep and put the transmission in reverse?

Just curious what's going on here.  Am I missing something?

[Dave WM]

I looked for it on the on line fsm, talk about it in the BE-104 but no pic, I could see it on my hard copy FSM.

[Dave WM]

found it figure BE154

in the body electrical section under discussion about the interlock. pretty sure a "buck up" is supposed to read "back up".

It's in the 1983 MT chapter.  Word.

I was thinking this one might be enough.

Yep the 83 5 speed only has the backup light switch. Not like the 4 speed with 3.

I'm only going to hook up the backup light switch during installation as that all the new trans has.

For the trans and diff oil are there any recommendations?

I heard many prefer Redline MT90, synthetic 75w90.

Also read some go as high as 140 which may be a little much.

Has anyone used Lucas synthetic 75w90 or Valvoline synthetic?

Both are at the local parts store were the Redline will need to be ordered.

pretty sure the FSM can cover the w for expected temps, I would just use that. Consensus (that guy knows a lot) says use yellow metal safe in the trans (brass anti balk rings) GL4, MT90 is often mentioned, and its what I have in mine.

[CRS]

Thanks. Manual mentions GL5 but I hear not to use. I'll go with the MT90.

Many people swear by AC Delco friction modified synchromesh transmission fluid  being superior to any other brand in the Nissan gear boxes.

There have been numerous discussions of this over the years.
