Daryl, where are the part numbers listed for all this?

Mike,
The part #'s are listed about half way down page 1 of this thread.

Sid,
I have no idea if they were available with an automatic, and didn't think to ask.
Victor Laury seemed to come up with quite a bit of relevant info so maybe he has an idea? Would seem like a reasonable assumption for those years.....

Cheers

This information should be put into the technical section of the main site, don't you think Steve?

Yes, you are correct Sid. I will work on it real soon!

A couple of pics of the trannies:
1st two pictures to compare Spl 4 spd with diesel 5 spd.



cut/weld required to mount diesel/240SX transmission


Fitting diesel/240SX transmission

Update on the shifter:

The 240SX transmission shifter position is slightly toward the back of centre of the '66 shifter cutout in the body.
And the 240SX shifter is angled back by 30* or more also, which means it hits the back edge of the cutout.....
I cut some of the tunnel away but really didn't like that solution, I picked up a shifter from an '86 200SX which is straighter, and the same style transmission, but the pieces are slightly different and won't just bolt in.....

So..... I turned the shifter around so the angle is facing forward! Works perfect! Shifting position is good and you hardly notice the angle.

At least,.... so far,.... in the carport,......Still waiting on my exhaust before I can tune the EFI and start driving again.......

Now I have to find some sort of gearshift boot setup......Any suggestions?

Get a boot for a Dodge Dart/duster..Oval, right size. I have an OK one you can have , just send me an address.

Otherwise, Hurst had a good assortment last time I looked.

Now that it works, send one to Will, if it survives, it's the ultimate trans swap.

Thanks for the tip Dave, I'll check out the wreckers or new. Between postage and customs it's too much trouble to send across the border.

I have 3 - 400 miles on this tranny now, the last outing was December 8th, for 4 or 5 hours with lots of runs through the gears, and a highway run where we hit 95 mph (according to my non-calibrated electronic speedo). I am very happy with the way the tranny shifts , and the ratios seem very good for everyday driving with this engine (1800)/rear diff (3.9)/ tire (185/65/15) combo.

Reading the other transmission thread reminded me that I hadn't posted some of the swap info, so here is what I had/did at the clutch end of the swap.....wish I'd kept better track of parts.......



1) Throw Out Bearing: I used the U20 bearing supplied with the clutch kit. Both the diesel and 240SX bearings will fit on the mount/slider (don’t know the proper name for this part). Are there any advantages/disadvantages to using one of the newer, larger bearings??

2) Bearing Mount/Slider: I ended up with 4 different Nissan pieces - Roadster 1600, 240SX, diesel, and one unknown. Unfortunately, I didn’t keep them separate/labeled and don’t know which I used……..

3) Flex Plate: I used the 1600 plate. Using a yardstick for a straightedge and a measuring tape to measure the distance out from the transmission housing to the end of the taper of the clutch spline on the mainshaft, it was very close, but looked like it would work without binding on the crankshaft. So Far, No problems……….A U20 flex plate is significantly thicker, and may be a better solution. Someone with better measuring tools/experience would be able to give a better answer to this query……..

4) Fork / Pivot: Again I had several of these on hand from the different transmissions and when the roadster or diesel parts didn’t fit, I mixed and matched to get everything to work properly. Sorry, again, I didn’t keep track of the parts used……


So....I guess if you are going to do this swap, you may want to have some different parts on hand to make it work.........

I love pragmatic wisdom.

Daryl, Daryl, Daryl....You have been working on this project since July '05 and you don't know what parts you used? How is anyone supposed to follow in your inventive footsteps?
OK, just giving you a hard time However maybe you can look and see what parts you have left over and those are the ones you DIDN'T use..process of elimination

Linda
68 1600
4 speed

I don't know how to identify the remaining parts as to which car/truck they belong to.....And have moved my shop, so really don't even know where the leftover parts are!!! (organization is not one of my strong points)

Well.....I do have another Diesel bellhousing here, and if the guy that owns it doesn't get started on his swap, I'll have to do something with it....
I'll do my best to get him to properly document that end of the assembly.....

I pm'd my mailing address, feel free to ship any spare parts that are in the way. I'll even pay the shipping!!!

Now that I'm completely confused, I'll keep my 4 speed

I found an SD22 and 5 speed trans for $300.00 in New York, but I don't know if I'm up for the challenge. anyone wants it, PM for info

BTW, does the SD22 crank swap into anything for a stroker It's a 3 main, from what I've found, been around since the 60's???
