Villeman Posted February 22, 2016 Share Posted February 22, 2016 (edited) Hello, i recently scored a 1992 200sx 5 speed (there was no 240 in Germany iirc, was still named 200sx) for my 280z 5 speed conversion [ 70.000 miles, 110$, all gears shifting]. So, the gearbox seems to be a 71C from the looks of it, but it has a "CA71B #2 Kangoroo" stamp on the bellhousing (no joke) .... isn´t this a 280z/zx bellhousing???? I hope i bought the correct one for the conversion.... Edited February 22, 2016 by Villeman Quote Link to comment Share on other sites More sharing options...
BluDestiny Posted February 22, 2016 Share Posted February 22, 2016 I think that may be a ca18 tranny. Quote Link to comment Share on other sites More sharing options...
Villeman Posted February 22, 2016 Author Share Posted February 22, 2016 (edited) hmmm, thats not good, right? I just read up on boxes and thought this would be a 71C. But it should be suited for a swap ? Edited February 22, 2016 by Villeman Quote Link to comment Share on other sites More sharing options...
NewZed Posted February 22, 2016 Share Posted February 22, 2016 Not clear if you're hoping this is the front case/bell housing or the gear set. Looks like you got a 71C gear set, that will need a 71B bell housing to work on an L6. The shifter is an easy clue, and the cross hatched bell. You can check the angle of the mounting holes also.

Villeman Posted February 22, 2016 Author Share Posted February 22, 2016 (edited) okay, thats what i wanted to hear i wanted to get a 71C 5 speed (late model) since it has more synchros etc. I was just wondering why there is a 71B bellhousing already attatched, and if I could use that one (instead of a donor one from a 4 speed) (and why they casted a cangoroo picture on there ...) Edit : looks like it´s a CA18DET gearbox which wasn´t sold to the US in this combination in a 200sx. So, is this a "good" 200sx box or some lesser suited box?

NewZed Posted February 22, 2016 Share Posted February 22, 2016 I've never seen a good explanation of what the B or C means. Most call the later transmission the 71C because that's what Nissan calls it in the 300ZX Service Manual, when the VG30 was introduced. But there are many other letters used. Even the early 71C's had the same synchros and gear widths as the 71B's, so once you swapped bells you had essentially a 71B with a different shifter and set of gear ratios.. But, the countershaft bearing size was larger fro the 300ZX 71C, so that's one definite difference. The later US market 240Sx 5 speeds with the extra synchros and wider gears were actually either a 71H or 71J (can't remember which), not 71C.. So, in your case, you might still have a smaller countershaft bearing, and an unususal set of gear ratios, and either the same number of synchros or more. I would find a Service Manual for 1992 European 200SX and see what it shows. Nissan's casting marks and numbers haven't been very useful, at least on the early Z's.

NewZed Posted February 22, 2016 Share Posted February 22, 2016 There are lots of variations out there. Length of the tail shaft case, for instance. Yours doesn't look like either of the two 240SX units shown in the popular writeups (Nigel/Motortopia and Steve/zhome), which also don't look like each other. Better triple check.

NewZed Posted February 22, 2016 Share Posted February 22, 2016 Sorry, I miswrote. Nissan still calls the transmission the 71C even in 1994, for the 240SX, US market. It's when you buy parts that you'll find the other letters. It's messy. This is from the 1994 Service Manual. Quote Link to comment Share on other sites More sharing options...
NewZed Posted February 22, 2016 Share Posted February 22, 2016 Here's an example - http://www.manualtransmissionpart.com/NISSAN-Cars-ID-Make-Model.html The parts places are all screwed up. Don't use them for any ID by number. Quote Link to comment Share on other sites More sharing options...
Villeman Posted February 22, 2016 Author Share Posted February 22, 2016 well, only one way to figure it out. Was going to open it anyways. Anybody has experience if the Bellhousing fits a L6 engine ? and thanks so far guys Quote Link to comment Share on other sites More sharing options...
NewZed Posted February 22, 2016 Share Posted February 22, 2016 I would measure length first. Overall, and each case, front and back. The smaller cars and trucks seem to come with shorter tail shaft housings. And you can see the countershaft bearing by popping off the front cover, no need to split the cases. Here's another example of ID code. "E" and "C". http://www.midwesttrans.com/webapp/catalog.jsp Good luck, have fun. Quote Link to comment Share on other sites More sharing options...
Villeman Posted February 22, 2016 Author Share Posted February 22, 2016 okay, thats what I will do next. As long as the core gives me a solid 5 speed for my Z I am good Quote Link to comment Share on other sites More sharing options...
BluDestiny Posted February 22, 2016 Share Posted February 22, 2016 That bellhousing will not fit an L series. It's made to match up to a CA. As NewZed said it's all the same tranny, KA/SR/CA all had the same 71c gearset (with some minor changed as pointed out). So if you wanted a 5 speed to do the swap, you just need to machine the L series bellhousing to make it work. Quote Link to comment Share on other sites More sharing options...

260DET Posted February 26, 2016 Share Posted February 26, 2016 One thing about Nissan is that they don't change bits from model to model unless there is a good reason for it, unlike those Germans who seem to change things just to make life more complicated The kangaroo could mean that the casings were cast in Australia.

Villeman Posted March 1, 2016 Author Share Posted March 1, 2016 Jup, it´s indeed a casting mark from Nissan Casting in Australia making things complicated? never! It´s called improving! (both the part and the chance of seeing you in a shop being miserable) Quote Link to comment Share on other sites More sharing options...
Xnke Posted March 27, 2016 Share Posted March 27, 2016 That transmission will work fine-just needs the bellhousing swapped over. The gear ratios are OK too. You'll need to drill the bellhousing for the 16mm shift rod, and cut it for the 62mm countershaft bearing, and clearance the boss on the back of the countershaft hole for the countershaft gear. It is *very* likely you will not need to modify your driveshaft either, when I've used a 200SX transmission from behind a CA20E or CA18DET engine it's always been the correct length to drop right in place. Same with early RB20E/ET transmissions. The shifter is NOT THE SAME as a later 240SX shifter, one bolt is in a different spot and one bolt is 17mm instead of 10mm. If you choose to go looking for an aftermarket shifter, keep that in mind! Quote Link to comment Share on other sites More sharing options...
Villeman Posted September 20, 2016 Author Share Posted September 20, 2016 (edited) sorry to bring this back up. Bellhousing from a 4 speed is machined and ready to go. Anyhow, the gears from the CA18DET seem to be bad. Is there any comprehensive guide to spot dealbreaker flaws? Don´t want to put millions of pictures up. thanks in advance! btw: no need to shorten the driveshaft????Really? Would be too good to be true Edited September 20, 2016 by Villeman Quote Link to comment Share on other sites More sharing options...
jacky4566 Posted September 20, 2016 Share Posted September 20, 2016 Why don't you row it through the gears and figure out the ratios? Put into first. Spin input 10 times and count output rotations. Repeat for all gears. This will help you identify what you have. Quote Link to comment Share on other sites More sharing options...
