Do you have the torque converter to go with the 4N71 transmission? Otherwise the OD gear won't work right. Also, there are two versions. L4N71B has a regular torque converter, and the E4N71B has an electronic torque converter. I'm not sure which one came on the Maxima, but the E4N71B version should have some wiring to make it work. A little more searching suggests that if it's a Maxima transmission, it's the L4N71B.

He also lifted the new transmission (a 720 box, not a 280Z box) into place, and we worked well together to get it bolted in. We verified the clutch engages and will disengage. Next Saturday, I'll put all of the parts back in...and fill the transmission.

I didn't take any photos of pressing it in, but the Maddox kit had the right adapter for me to set it up and tap it a couple of times with a mallet to drive the collar into the TO bearing. It was nice having someone with experience come over and supervise.

As I'm a complete novice to most of the transmission topics, this was a neat learning opportunity for me. I needed to separate the TO bearing and collar for installation of the new transmission. After consulting with a couple of friends, I decided to try the Maddox Ball Joint Service Kit I bought from HF. I found it had the right size collar for the TO bearing, and then I found a 27mm socket would drive out the collar. Here's the assembly ready for pressing. It worked for the most part, but the bottom plate kept the assembly from driving the collar all of the way out. I could try using my vice to finish the job, or I could get medieval. It worked.

I wonder if a radiator repair shop could fix that crack?

Maybe they needed something else to maintain pliability. This calls for a Google search...that didn't reveal anything. Have you considered treating with petroleum jelly or glycerin after the wintergreen oil has done its job?

I'm happy I could help. I love keeping these cars on the road (or track) where they belong.

I pulled the 260Z transmission today. Here's the drain plug. That piece of metal lying on the floor was also attached. I also took a picture after I cleaned it. The oil coming out of the transmission was very pretty, all full of glitter. 😲 Soon I had everything else clear, so I was ready to drop the transmission. All I had to do was pull one bell housing and two transmission bolts. After I finally got the transmission clear of the engine and header, I lowered the transmission jack, and the transmission promptly rolled off the jack. I dragged it out to prepare to install the replacement.

Yes, it's a 280Z 5 speed. No, there isn't a new diff at this time. I'll be using the 3.364 rear end. It'll only drop about 500 RPM or so in 5th, but I'll be happy with that improvement.

Good to know. I'm doing the reverse soon. I'm dropping the old 4 speed out of the 260Z today if all goes as planned.

That's in USD. @zKars posted the CAD price.

If it's hardened, it's reasonably priced.

Your memory is correct. As for access to the body, if you think about it, the filler neck goes through the fender. At that point, the neck is above the rear floor, so it briefly runs through the cabin on it's way down to the tank. Those two holes shouldn't pull in exhaust, though.

So inquiring minds want to know make and model of the bead roller...

Different groups of engineers and translators could easily account for different names.

Are you referring to this? https://www.nengun.com/fujitsubo/legalis-r-exhaust-system

Just for reference, the part number is 28820-N3300. Part #44 here: https://www.carpartsmanual.com/datsun/Z-1969-1978/electrical/electric-unit-switch/section-1/240z-260z

They change the names but #9, Intermittent wiper relay, and #1, Interval wiper amplifier, are one and the same. I hope this clears up your confusion.

Well, on the flip-side, they aren't publishing a bunch of articles with bad information. I hear enough wrong information about the Zs at car shows to keep @HS30-H busy with his voodoo dolls all day long. Many times, I reply with, "No, that isn't true," or "That is in the realm of urban legend." On more than one occasion, I have heard that Nissan bought Datsun because Datsun went bankrupt. As for Hagerty, what comes to mind is the last line from Chinatown. "Forget it, Jake. It's Chinatown."

Could you put the two diagrams into a new reply? I'm not seeing what you're seeing.

I can guarantee going home in reverse was not an option for me. Just listen to the video. There's actually only one clunk in first. I let the car die after the clunk. At least I have the replacement box on hand (280Z 5-speed). I'll probably start on the teardown on Saturday. I'm trying to coordinate with someone I know to make a housecall on Sunday to put the 5-speed in. clunks.mp4

If you're really worried, search for closed cell foam. https://www.amazon.com/Trisiki-Insulation-Automotive-Conditioner-Protective/dp/B091GNCK1G

If it blocks wind from coming into my house, it probably will stop exhaust from sneaking past your taillights.
