CA18DET transmission rebuild kit ... which one to use?

Post by **blownhemi** » Fri Mar 05, 2010 10:37 pm

I've read before, that CA and KA tranmissions are the same except for the bellhousing. FSM also states, that both are FS5W71C model transmissions.

This page, though,http://www.drivetrain.com/part....htmllists FS5W71H for all the 240SX's, with '88-'93 240SX needing the DTS-BK133BWS rebuild kit.

Would this kit also work for the CA18DET transmission? Has anyone ever tried this?

They are slightly different. If the rebuilds contain new gears you will be changing your 5th gear ratio.

S13/S14 (KA24DE) 240sx M/T Gear Ratios1st- 3.3212nd- 1.9023rd- 1.3084th- 1.0005th- 0.759Reverse- 3.382

S13 (CA18DET) M/T Gear Ratios1st- 3.3212nd- 1.9023rd- 1.3084th- 1.0005th- 0.838Reverse- 3.382

Oh yeah, true, I forgot to check this.

It's just a basic rebuild kit with bearings, seals and synchros. So the 5th synchro might not match because they are of different gear ratios?

But then again, 5th gear synchros are not the ones that usually wear out anyway.

I dont see why the rebuild kit wouldnt work. I would give it a shot.

Post by **blownhemi** » Sat Mar 06, 2010 10:32 am

Yes, me neither.

I'm just contemplating whether a rebuild will solve my problem. When the tranmission is hot, my shifting becomes harder. When hot, and I want to switch into 1st while standing still, I practically have to FORCE the lever into 1st. It is not grinding, there is just a really strong resistance. Maybe it isn't a synchro issue.Any thoughts?

Post by **zmannz** » Sat Mar 06, 2010 2:42 pm

Simple just tap the gas and quickly push the clutch in while moving the shifter toward 1stwhile releasing the brake, the stick will slide right in gear. Ever driven a trans with no syncros?

Hmm, almost sounds like a gear oil problem. What are you running? It's the same syncro for 1st and 2nd (just different sides of it) are you having problems with 2nd as well? This may sound weird, but try putting it in reverse, then put it in 1st. If it goes in, then LMK what you figure out that fixes it because I have the same problem in my civic, LOL!

I don't know, which oil I have in there, haven't changed it yet (just bought the car last summer). I took two or three longer trips, and in the end, when I arrived into the residential area, and had to change gears, it was all very hard. 1st, 2nd very much, 3rd not so hard, but still not normal. Again, no grinding at all, it's just really hard to pull the stick.Compared to my similarly aged 1.5 diesel DD, at least.

I can't try the putting in reverse thing, the only trip I'll be doing is ~2 miles to a garage to pull the engine, and while it's out getting machined, I'll change the oil in the transmission. I guess I'll see after that. Next long trip will be the break-in.

But I'll probably get the rebuild kit, $170 is not bad for an almost new transmission, and my trans. bearings are definitely worn.

try changing the oil, if that doens't work put it in neutral, then into 3rd, then 4th. do this a couple of times (it aligns the forks). Try going through the gears, is it still hard?

Sounds like you have either a poor fit between the hub and sleeve or the cone clutch isn't working well. If its not the fluid, both of these require a rebuild kit regardless.

I have a euro spec '89 ca18det (according to the FSM, hence the car was imported from Germany)... so which rebuild kit will I be needing? The manual says I have the FS5W71C...

according to http://www.drivetrain.com/part...5W71C

200SX 4 cyl 1.8L 1984-86 Aluminum case, rear load - Turbo DTS-BK133 $109.29 DTS-BK133AWS $130.46

Is that the correct one?

I'm confused...so many options...

Post by **blownhemi** » Sat Mar 13, 2010 6:11 am

I actually ended up ordering the kit in the first post, but it will be at least a month, or more like two, until we're pulling it apart. I want to to try float's and sjb's suggestions first.Is yours in a desperate need of a rebuild?

Post by **ska69** » Sat Mar 13, 2010 7:39 am

yeah, I guess I'm also looking at a rebuild...my problem (before the car was put away for winter) was that the car wouldn't move at all after a stop (e.g I drive it out of the garage, leave it idleing for 15-20 minutes, and then it just won't move...putting into different gears, and turning on-off the ignition didn't help). the problem simply dissapeared the next day (after the car was pushed into the garage)... I was told by the previous owner, that the syncros are subject for replacement..

Anyways, hence my car is a complete mess, I'm looking for a complete overhaul of all parts

Post by **ska69** » Sat Mar 13, 2010 7:43 am

could you explain why you got the DTS-BK133BWS kit for the FS5W71H transmission (if it's the KA transmission ?) when the FSM says that we have the FS5W71C transmission ?

I don't know if this would be a pure synchro problem. If it was synchro only, I think it would grind terribly while you put it in gear. But as I understood, you can put it into gear, but it wont move. Clutch issue, maybe?

Mostly, beacuse the 240SX's FSM also tells, that it has the FS5W71C... box. Plus, I figured, since only the last letter doesn't match, they can't be that much different, maybe just the 5th gear ratio, or some other small thing independent of the rebuild kit. And Nissan definitely wouldn't have wanted to make loads of different transmissions either, parts supply for maintenance would be a headache that way.

could be the clutch, as it's also almost finished...

what I was trying to say in regard of the rebuild kit -

it's DTS-BK133AWS rebuild kit for the 1.8 200sx with FS5W71C transmission, and the DTS-BK133BWS is for FS5W71H for the 240SX with FS5W71H transmission. why the DTS-BK133BWS when there is a DTS-BK133AWS for a 1.8 + FS5W71C available? maybe I didn't understand something? the DTS-BK133AWS won't work or there is some other explanation to this?

I just regard the FSM to be a more accurate source of information, than a website listing, so I rather chose the same model year and same chassis (AND same trans. code as per FSM), than choosing an older model year, older generation chassis, despite correct trans. code.But it's all just speculation, and this is how I've decided. I might end up with a kit half of which I won't be able to use...

Post by **ska69** » Sat Mar 13, 2010 10:45 am

wait, your FSM says that you have FS5W71H not FS5W71C?

Post by **blownhemi** » Sat Mar 13, 2010 11:06 am

ska69 wrote:wait, your FSM says that you have FS5W71H not FS5W71C?

No, it says -C. I meant "same", as in same -C trans. for '89-'93 240SX and '89-'93 S13 200SX. I just ignored the trans. codes on the website, and I chose by make and model year.

Post by **ska69** » Sat Mar 13, 2010 11:59 am

ok, I understand you now but I think it should be the DTS-BK133AWS kit, hence the s12 had a ca18det as well, if I'm not mistaken...I guess I'll go with that option

Post by **DALAZ_68** » Sat Mar 13, 2010 7:01 pm

so my trans just went out...

and im just wondering

KA 89 - 98 tranny gear box + CA bell housing = win?

From what I've read so far, this should work. But I don't know if the S13 and S14 are the same, output/input shaft length wise. Maybe some else can tell?I'd look for a KA trans from the same chassis in any case.

should be, think about it...

89-98 KA trannies are interchangable between 89-98 KA motors...im just not 100% sure on the CA though...

Post by **sjbsuperman1425** » Sun Mar 14, 2010 7:32 am

yes

KA trans + CA bell housing = Win

you'll just have a taller 5th grear IIRC

Post by **DALAZ_68** » Sun Mar 14, 2010 9:44 am

anything you guys recommend i should replace while i can...

Post by **sjbsuperman1425** » Sun Mar 14, 2010 9:54 am

resurface flywheel, clutch, TO bearing, pilot bushing, rear main seal maybe. if you have the cash i'd try and just rebuild the tranny you are putting in.

BUT i go by this motto: "if its not broke, dont fix it".

lol...but my transmission is broke...and i need to fix it be4 april 11th...my next event...

i found a transmission that needs a rebuild...might aswell... whats a good price for a transmission rebuild with oem nissan parts ?

and i might just replace the slave cylinder as well

Post by **DALAZ_68** » Mon Mar 15, 2010 7:24 am

also wondering...could i used the front oil cover (part number 32110 http://www.courtesyparts.com/2....html ) from a KA...or do i only need to replace the oil seal behind that (Part # 32113)and gasket?

So witch one did you go for, already have it? Is it a match?

the front covers are the same so use either one you want
