240swapped Posted November 1, 2007 Share Posted November 1, 2007 I've seen this video too many damn times to count and just now noticed that 1st gear is in the bottom of the shift patter. what tranny is in the Spirit Garage 240Z? http://www.youtube.com/watch?v=mo0WeyGFSDA&rel=1">http://www.youtube.com/watch?v=mo0WeyGFSDA&rel=1"> Quote Link to comment Share on other sites More sharing options...
HS30-H Posted November 1, 2007 Share Posted November 1, 2007 Its an F5C71-B Nissan 'Sports Option' 5-speed transmission ( note the difference with the FS5C71-B - which was an Overdrive 5-speed with a conventional shift pattern ). The shift pattern of the F5C71-B transmissions is what is nicknamed 'Low Back' in Japan, and also 'Dog-Leg First' elsewhere. First gear is all the way left and back ( on the same plane as Reverse gear ) with the other four ratios in a conventional H pattern - which is useful in racing. Helps avoid wrong-slotting. Note that this is a 'Direct Drive' trans: Fifth gear is 1:1 rather than an Overdrive. They came in four different 1st to 4th ratio sets. I have one in my Skyline. They are nice to use on the track. Changing hands for more and more money these days.......... Quote Link to comment Share on other sites More sharing options...
240swapped Posted November 2, 2007 Author Share Posted November 2, 2007 i've got a bunch of parts i bought with 2 shells, and i think i may have one of these transmissions. is there any distinguishing factor in the body/casting of it? does it use the same driveshaft?

HS30-H Posted November 2, 2007 Share Posted November 2, 2007 Externally, the F5C71-B looks just like the FS5C71-B - so I think you will have trouble correctly identifying one without knowing what you are looking for. Shift pattern however should be easy to discern: R 2 4 1 3 5 They used the same propshafts as the other 'B' types. If you want to identify the exact ratio set installed ( Race Option #1, #2, #3 or 'Rally' Option #4 ) then the only sure way to do it is to take the case apart and start counting teeth on gears..........

Skids260 Posted November 8, 2007 Share Posted November 8, 2007 The dog-leg five speed also came in the 200sx here in the states. Thats what i have in my 510. Quote Link to comment Share on other sites More sharing options...
HS30-H Posted November 8, 2007 Share Posted November 8, 2007 The dog-leg five speed also came in the 200sx here in the states. Thats what i have in my 510. That would not have been an F5C71-B though. USA 200SX would have most likely had an FS5W60L, I'd have thought (?). Quite different. Quote Link to comment Share on other sites More sharing options...
Skids260 Posted November 8, 2007 Share Posted November 8, 2007 Im almost positive its not a "race" transmission. And i dont know any of the serial numbers, all iknow is that when i put it in 1st it down and to the left. Quote Link to comment Share on other sites More sharing options...
