Help ID this 5 speed

[EVILC]

I have this 5 speed that came out of the 71 24o I bought a few months back. I have searched here and Hybridz and I think I know what tranny it is but I would like to make sure. I believe it to be a euro 5 speed..please see pics:

Complete tranny:

Some casting:

Shifter:

I can take other pics if needed. The car was serviced at Bob Sharps dealership through the 70's...so I will ask him next month when I see him about "swaps" they might have been doing back in the day. I just know these 5 speeds don't come up to often and I wanted to make sure I have my Z knowledge down here

So it safe to say these trannys came in the 240's none US and also are referred as a dog leg tranny? Thanks for any input guys.

What makes you think it's a 5 speed? Looks like a 4 speed to me. Have you driven the car with it in?

Sure looks like an F4W71a to me. How do you know it's a 5-speed? It's not an FS5C71a or b. I suggest a search through the archives will turn up some interesting info.

Don't know what it is but it's not a 'dog leg'. The dog leg was a later 5 speed used in the US on 4 cyl cars in the late 70s/early 80s. They have reverse where we're used to having first gear. I'm talking US market trannies. If there is a non US 5 speed with that shift pattern I'm not familiar with it.

IIRC, there was a direct drive five speed available from Datsun Competition. Was that a dog leg? I always liked the dog leg pattern as once you are moving you rarely use first again so the gears that you use the most are in the typical H.

I've seen those listed in the early Dastun Comp catalogs. I remember that they were listed in three ratio options. I don't recall any mention of the shift pattern, however.

I did not drive the car at all but I have shifted it into every gear and turn the shaft to double check it being a 5 speed (done out of car). "Normal shift pattern" with reverse down to the right. So now I know exactly what a dog leg tranny means....and this is not one. So that rules out a few trannys. I just went outside again to double check where each gear is and I am still getting 5 gears, 1 reverse. I may have to check the ratios if I get the time. Thanks so far for the help.

[sblake01]

I wish I knew more. I could quote the ratios from the old Datsun Comp. catalogs if that would help but I don't see how it would.

Here is a link that I am sure many of you know of: http://www2.zhome.com:81/ZCMnL/tech/69-83TrannyShifterDrawing.jpg

So I know it is a "monkey motion" tranny.

There was a 5 speed 720 truck('79-'85)transmission that will bolt into an L-6 car, that also has "lower" gearing. However, there were two other sets of different gear ratios available, depending on the truck model:

#1 #2 #3

1 3.592 3.321 3.592

2 2.246 2.077 2.057

3 1.415 1.308 1.361

4 1.000 1.000 1.000

5 0.813 0.833 0.813

Does anyone have pics of this tranny or know first hand what they look like?

I agree, I think this is a regular type A four speed. The early 5 speed (FS5C71A) has a different tail housing with a flange that bolts to the drive shaft. Here are a couple of pictures of a NOS one that was for sale in the classifieds recently.

I tried the hand spinning of the input shaft and watching how it related to the output shaft and couldn't determine anything for sure, but could detect 5 forward gears when I was trying to figure out the ratios of my 5 speed. I notice yours still has the remmants of red paint we discussed in a previous thread about production markings on the early monkey motion 4 speeds. The Non-US version you mention would be the FS5C71A, but Chris has ruled that out. It is not a F5C71B which was available as a flange type or sleeve type, either as evidenced by the shifter type. All I can suggest is, you are getting a false feel for a 5th gear being present, but I ain't no expert.

Ron,

I was thinking the same think you mentioned---false feel of 5th. At the same time, I had two other Z guys over and they "felt" a fifth also. This is why I posted because my head was starting to hurt reading here and other sites. I am going back outside again and going to make sure I am getting a fifth gear.
