NismoZ Posted November 19, 2007 Share Posted November 19, 2007 Hi all, I have a quick question about a tranny i bought today at the local junk yard.Sorry if this should be known but i have searched and have found no answers to this. Anyways i found this tranny laying by a 1982 280zx 2+2 and wanted to know if this was the tranny that went to it, it has a flat plate by the shifter with a sensor by it.thanks Quote Link to comment Share on other sites More sharing options...
Careless Posted November 19, 2007 Share Posted November 19, 2007 looks a lot like my 4 speed, but can't say for sure. i've only ever seen the bottom of it, and from my shifter hole, it looks as it would from the top. but I think the clutch fork hole is on the opposite side, no? id like to know too. perhaps its a 5speed (not BW T5 though) this website shows similarities: http://www.zhome.com/ZCMnL/tech/BorgWarner.htm Quote Link to comment Share on other sites More sharing options...
NismoZ Posted November 19, 2007 Author Share Posted November 19, 2007 I hope its a 5 speed since i bought it to convert my z.Thanks for the link i saw that one when i was searching around and thought i found my answer, the only thing is it doesn't have the flat plate and sensor on the top.So im still iffy about it.

Dragonfly Posted November 19, 2007 Share Posted November 19, 2007 Looks to me like a very typical (what I call it anyway) 280ZX Type A transmission, which is a 5 speed. A lot of people prefer the Type B because of the gearing but it is still going to be a step up from the 4 speed that it replaces.

NismoZ Posted November 19, 2007 Author Share Posted November 19, 2007 Thanks for the reply Dragonfly,So i am assuming this tranny is not a 81-83 tranny? is there any part number i can look for to verify it Quote Link to comment Share on other sites More sharing options...
Dragonfly Posted November 19, 2007 Share Posted November 19, 2007 I have only seen one Type A (1979-1980) in person but have owned several Type B (1981-1983) transmissions. From looking at the pictures you have posted the tail portion of the transmission looks less like the Type B's that I have owned and more like the Type A that I had seen. I do not know off the top of my head what the numbers are or where they are located, I have been running a T5 for a number of years now and have not paid much attention to the "normal" Nissan transmissions for a long time.

NismoZ Posted November 19, 2007 Author Share Posted November 19, 2007 well i just pulled the cog out and it has a yellow 16 tooth cog in it, so i dont know. Quote Link to comment Share on other sites More sharing options...
Dragonfly Posted November 19, 2007 Share Posted November 19, 2007 well i just pulled the cog out and it has a yellow 16 tooth cog in it, so i dont know. The color of the cog indicates what the rear diff gear ratio was, there are several different colors and each color is for a different ratio. If I remember correctly the yellow is for a 3.7:1 diff which was common in the 2+2 280ZX's, so that increases your chances of it being from that car, which in turn increases your chances that it is a Type B. I may have in the back on old (very dead) Type B transmission, I will take a look tommorow afternoon and give you a better answer then if no one else jumps in here before then and gives you an absolute answer.

Hyuri Posted November 19, 2007 Share Posted November 19, 2007 A quick Google spat out this thread. Also: have some shots of a (guaranteed!) '83 5-speed tail. I'm pretty sure an '82 would look like this. Quote Link to comment Share on other sites More sharing options...
1 fast z Posted November 19, 2007 Share Posted November 19, 2007 There was NEVER a 3.7 offered in a inline six powered car. Only in the Z31,s. Quote Link to comment Share on other sites More sharing options...

1 fast z Posted November 19, 2007 Share Posted November 19, 2007 R180's, and there not z cars. Quote Link to comment Share on other sites More sharing options...
HowlerMonkey Posted November 19, 2007 Share Posted November 19, 2007 Funny but there is only mention of inline six nissans in this thread and a first generation maxima is a inlline six nissan. Did someone write "R200" in invisible text on this thread because I'm just not seeing it? Also.........many pre 1981 280zx came with 3.7 R180s. In 20 years at various nissan dealerships, I have seen many. Quote Link to comment Share on other sites More sharing options...
HS30-H Posted November 19, 2007 Share Posted November 19, 2007 Not in the US. COUGH. The US market cars are all Japanese cars. The ratio existed. Nothing was stopping it from turning up should somebody have specifically ordered it, and as far as I know US Customs didn't turn away those 'GI Bride' non-US market cars that keep we see turning up over there from time to time. Never say never. ( nasty cough you have there by the way )...... Quote Link to comment Share on other sites More sharing options...
steveosupremeo Posted November 20, 2007 Share Posted November 20, 2007 that trans looks like my 4 speed with that plate on top of it. and a yellow 16 tooth cog would specify a 3.36 ratio, not 3.7. Quote Link to comment Share on other sites More sharing options...
Dragonfly Posted November 20, 2007 Share Posted November 20, 2007 that trans looks like my 4 speed with that plate on top of it. and a yellow 16 tooth cog would specify a 3.36 ratio, not 3.7. I've been looking all over for my list of color to ratio for the gears and as of yet have not found it, but I did find a partial list that indicates you are correct. I looked at the Type B 5 speed I have in the back and the transmission shown in the above pictures is not the same, there are to many differances in the tail portion. My 260 FSM shows a picture of a 4 speed that resembles the pictures posted above but they are all sketch pictures and I can not say for sure if it is the same.

steveosupremeo Posted November 22, 2007 Share Posted November 22, 2007 this might help some, there may be some variances in colors but this is what i have found so far. yellow 16 = 3.36, black 17 = 3.54, turquoise 18 = 3.70, white 19 = 3.90, red 20 = 4.11, purple 21 = 4.38. i have also heard of 4.4? ratios, maybe there is a cog for that one but it wouldn't coincide with the proportion of teeth:ratio. anyway, someone who is more familiar to chime in would be great, thats just what i've seen SO FAR.
