Datsun FS5W71B Close Ratio 5 Speed Transmission

---

This FS5W71B 5 speed was removed three years ago from a low mileage 1983 280zx with its original engine. The transmission was full of oil and did not leak so the seals were left intact. When drained, the oil was in great condition and the magnetic drain plug had one shiny sliver of metal which appears to be casting flash (item #1 in the drain plug and dime pic) and two chips of magnet (items #2 and #3) stuck to it. These appear to be from the plug magnet itself- as seen in the picture that the edge of the plug magnet is missing a small piece. It shifts smoothly through all forward and reverse gears and has no friction spots or noises as the input shaft is spun by hand or drill in each gear. The input and output shaft gears themselves are also in mint condition. The aluminum case was cleaned with a nylon bristle brush and left in its unpainted original condition. The speedometer cable end is installed to protect the threads in transit.
This is the very hard to find 1983 Datsun close-ratio 5 speed transmission that was only installed in the last two years of the 280zx model-1982 and 1983. It fits S110, CA18ET (200SX), L20B, L16, L18, L24, L26, L28 and L28E engines as well as MGB's with the Rivergate conversion. The '82 and '83 models have the great overdrive 0.745 fifth gear which allows for a comfortable cruising RPM even with high rear end gears. 

I purchased this transmission three years ago for my '71 240z project but my build has taken a different direction and I no longer need it. Here is how to positively identify this transmission model:

1. The oval block off plate with two bolts on the drivers side which is the reverse lockout (prevents clipping reverse on 5-4 downshifts).

2. A single exhaust hanger tab on the tailshaft housing.

3. No dustcover where the tailshaft exits the housing.

4. The speedometer cable connector tab machine screw is on the bottom, not the top.

5. This transmission's shifter mount has the taller 'ears' (1983 only).

The good folks at California Datsun have made a video showing the differences here: https://youtu.be/UrdQZeh7GsU
 

The auction includes the transmission with the original shift lever and shift lever pin (taped to the shifter) and the lower transmission mount as shown in pictures. It will be shipped dry, wrapped and strapped to a small pallet.

Will also ship from Great Falls, Montana as we will be visiting there in the next few weeks.

So this is an eBay auction?  Why did you break up the url?  Just make it a click-through.

Starting bid $1100.  Buy it now $1875.  And the part is in Canada.  Good luck with that.

Will be interesting to see where the auction goes. Let free enterprise and the capitalist way do its thing.

You really think its worth that much Jim?

Maybe let Kent know.... @ConVerTT

Interesting piece ... seems a bit pricey but I guess we'll find out

I have no idea. Demand for these is quite high. I’ve seen a few asking prices around this level.

Imagine if it had the 62mm front countershaft bearing and was freshly rebuilt and painted pretty?

I missed the "C".  So $832 USD opening bid, $1418 buy it now.  Still up there, not so bad though.  No bids yet.

Still cheaper than CD.

The last time I bought one they were going for about $300

Thanks for noting the dollar exchange difference Zed Head.  As commented elsewhere the transmission was borderline impossible to find when I was trying to buy it.

My wife and I are going to visit Great Falls, MT in a few weeks so I would be happy to ship from there to save my American brothers on shipping costs.

Hey SGt!  Welcome to the forum!  I am in Calgary!  Tell us more about your ride!

Hello! Thanks for the welcome. I work in Calgary and commute from Dunmore every week.

My '71 240z #10714 is a very clean original California car imported to Canada by the fellow who sold it to me. I found it on Trader in Smithers BC. The owner drove it three hours to Prince George to meet me and had shipped his spares pallet by FedEx to give to me. I bought it on sight. Got the pallet loaded into my truck at the freight depot and brought the car to Calgary on a trailer (see pic).   He had it in the garage for 7 years waiting for his son to be old enough to restore it with him. Turns out his son didn't care for cars. Bad for Dad, good for me. Later on I drove it to the Hat and began the build. Painful drive with the stock engine and a 4 speed!

It has solid floors, battery tray and spare tire well but rust in the bottom of the dog legs.  Stripping the whole car by hand revealed one repaint and minor fender benders on the DS quarter and PS front fender where the panels had some bondo over a small repair. It had the original driveline.

 I've been working on it for 18 months but as I"m out of town during the week it goes slowly.
