Gensaiken Posted April 15, 2008 Report Share Posted April 15, 2008 Hey, Just wondering if there is a way to identify a trans comming out of 620 if it is actually a 5speed (other than just running though the gears) and if it is actually from a 620 or not. A transmission looks like every other transmission to me.. so any ways to identify it would be appreciated. I just like to make sure I'm getting what i'm SUPPOSED to be getting. :D Quote Link to comment
MrRobatoGato Posted April 15, 2008 Report Share Posted April 15, 2008 Are you look for one or do you have one you want to identify...? Quote Link to comment

Llittle_Llama Posted April 15, 2008 Report Share Posted April 15, 2008 i want a 5 speed..... Quote Link to comment
Pacific coast Datsun Posted April 15, 2008 Report Share Posted April 15, 2008 Im sure there has to be #'s that set it apart from a 4 speed stamped into it. Or another way to tell is if it's longer than the 4 speed [short tail]. I believe all 5 speeds are long tails. So measure the 4 speed & bring a tape measure with you :D Quote Link to comment
datsunfish Posted April 15, 2008 Report Share Posted April 15, 2008 The long shaft 4 speed has a removeable acess plate on the top rear where as the 5 speed is solid.The dogleg 5 speed compared to the 4 speed has less ribs on the bell than the 4 from what I remember.There are a couple other small differences with the dog and short 4 like maybe the mount or input.Never removed the dogleg all the way.

It'll be for sale as soon as I have it checked out to make sure it isn't destroyed.

Thanks for the help... I think some one needs to put together a trans identification guide or something.. Quote Link to comment
OL YELLER Posted April 15, 2008 Report Share Posted April 15, 2008 I believe that Datsunaholic did that not too many moons ago.....the number is stamped on the top of the tranny...(I think...dang it, this oltimers disease is gettrn bad!!!) Quote Link to comment
Gensaiken Posted April 15, 2008 Author Report Share Posted April 15, 2008 Hmm, looks like it came out of a 620 but it isn't a 5speed. Unfortunately since it was sitting outside it was hard to shift and find out. After a little bit of shifting it got a bit easier and the patern is definately 4speed. So now I need to see if the guy will give me my money back since he said it was a 5speed. Quote Link to comment

datsunaholic Posted April 16, 2008 Report Share Posted April 16, 2008 That's a common F4W63 4-speed. If it came out of a 620 it came out of a '72-73. More commonly it's a stock 510 trans. No 5-speeds have that bottom cover. There are long and short versions of just about every trans, and a ton of misinformation (some of which I'm guilty of providing as I had never seen several variants). F4W63: 4-speed, sometimes called the monkey motion shift because of how the linkage is setup. Shifter is run through the shift collar with 2 tapered rubber bushings, and threaded with a nut loching it together. ID'd by having very visable external ribbing on the case and a removable bottom pan. Speedo drive pinion is on the DRIVER's side, the only L-series trans so equipped. Application: '66-69 520/521 and 410 w) J13 engine (shorttail with J-series case) '68-73 510 (shorttail with L-series case) '70-72 521 (shorttail with L-series case and a flanged output) '72.5-73 620 (shorttail with L-series case, same as a 510) '73-75 610 (LONGTAIL with L-series case) F4W63L: 4-speed, essentially a minor mod of the original 63-series trans. Major difference is the speedo pinion is moved to the passenger side, and the ribbing is not as pronounced on top. Still retains the bottom cover. Application: '74-77 710 (L-series front case, I believe it to be shorttail) '78-79 510 (L-series case, shorttail) '80-81 510 (Z-series case, shorttail) F4W71A: 4-speed, stock on the early 240Z. Don't know what years, at least '70-71. I believe it was also the late Roadster 4-speed with the R bellhousing. I've never seen one so I can't comment on what they look like, may have had the early shifter, but it was no longer in use by 1973. F4W71B: Identified by having a removable cover plate over the linkage on the extension housing (the only trans I know of that does). Pinned linkage shifter. No bottom plate. All the ones I've seen have 2 "ears" on the extension housing. Application: 240Z/260Z/280Z 1973-78 (maybe '72)- longtail L-series 620 '74-79 - longtail L-series 810 '76-80 longtail L-series 720 80 longtail L-series (at least 2WD) 720 81+ (longtail NAPS-Z, don't know when 4-speeds were phased out) Possible use on 720 diesel with SD bell pattern I don't believe there was a short-tail version of this transmission, but possibly on a 4-speed 4X4 720 82+. Short-tail versions did not have speedo pinion if they did exist. List is not all inclusive. Plenty of 5-speed info out there, so I won't repeat it. Quote Link to comment

I'm suprised it hasn't shown up on The620.com since they have a head guide. Also, you are dead on with the year. I didn't have time to read it at the time but it had some wrecking yard yellow scribbling on it. Turns out it says 73 Datsun on it. I guess I will take this as a learning experince, hopefully it doesn't cost me too much :rolleyes: Quote Link to comment
datzenmike Posted April 16, 2008 Report Share Posted April 16, 2008 Doug, the 4 speed was an option through '83 and not used with the 'new' Z24 engines starting in '84 through '86. Interestingly the next gen D-21 Hardbody did have the choice of a F4W71C type 4 speed (or a 5 speed) in '88. I've seen one in a hardbody. Quote Link to comment
datsunaholic Posted April 16, 2008 Report Share Posted April 16, 2008 Yeah, I wasn't sure. I'd seen an '81 with a 4-speed, but never later. Quote Link to comment
