2 different CA RWD transmissions

[ragenasian]

I wish I was there to take pictures but I sold a CA transmission from my wrecked 1990 200sx (of course euro model stock with CA). The guy I sold it to has a 1990 200sx with the CA in it also. Same year, same car, same motor but my Ca transmission was different. A good friend of mine and the guy who bought the transmission said there was a noticeable difference in the bell housings and the starter location. It was also said the transmission I had had two more sensors and a vacuum line.

Has anyone ever heard of this?

I really wish I would have had pictures of this but my friend that was there confirmed it and he is a pretty damn good mechanic.

Any thoughts????

intresting.....maybe it was just a differnt transmission from say an s12 or a differnt ca rwd, possibly the s13 non turbo ca?

[ragenasian]

All CAs here are turbo, I have yet to see one non turbo. Also it seems that a few 8 ports made their way into the CAs here and I thought maybe, just maybe, that had something to do with it, but both of ours were 4 ports too.

strange. any idea if the gear ratios were different? or was it just the housing?

[ca18datsun510]

vac line?

what?

[themadscientist]

I seriously doubt it. There were old and new RB20 trannies but every CA transmission I have pulled both DE and DET were the same. My 180 is using a Silvia DE box. The starter placement must be the same or it won't bolt up to the block. It was possibly another Nissan gearbox for another engine.

CA18DE RWD had a different gear ratio than the DET RWD. I'll try to find the link that shows all the different nissan specs.

gotta love that direct fourth gear for hauling balls.

Hey TMS I pulled the transmission myself. The one with the different bell was the one that came off my CA. This is why I am so pissed I didn't have the guys take some pics . My buddy said there was definately noticeable difference in the two trannies. Plus I spoke with the guy again and he said with both of them side by side you could definately tell the starter location was off. He said the trans itself looked identical with the difference being those two extra sensors and the breather or vac line. If I remember correctly it was some type of vacuum line. When I pulled it there was a hose running off the transmission we had to pull. Since the car was scrap at that point we didn't look where hoses went we just cut them.

[themadscientist]

so you actually saw the engine it was bolted to? If so did it have a goofy looking small plenum manifold with the TB aimed across the top of the engine?

[ragenasian]

This transmission came off my blue 200sx with the stock CA18det with the normal stock intercooler piping that I smashed into a tree. Definately turbo and definately RWD. I am confused about this just as anybody else. These were both the same year cars, same motors, save EVERYTHING except the transmission. His did have A/C though which was uncommon over here in that year. Both had the pig nose front bumpers also.

[roplusbee]

Damn. I didn't know you wrecked your 200sx. Wish I would have been paying attention, cause I would have bought some parts from you. Did you get another S13?

[themadscientist]

I can only guess it was a 88.5 model that may have had a leftover S12 transmission. I am not sure about the CA but I know early RB20 transmissions in the Laurels were bastards as well.

[ragenasian]

Yeah I wrecked the blue one I had. It was about a year ago, then I bought another red 200sx with a blown CA and when I said blown I mean I pulled a rod through a hole in the oil pan. Plus there was a Fist size hole in the side of it. Got it and put another CA back together with the three motors I had sitting around but just couldn't get it running right. Sold it for 2000 bucks and the kid that bought it still hasn't squared it away. So now I have another 200sx red of course and mostly stock which cost me 2000 bucks .

Well TMS all I can say is it didn't work which is bugging me. I know my current CA transmission doesn't have any lines running to it so I guess keeping this transmission isn't going to work for me either. Oh well just thought I would throw this out there as I have never run into a different CA transmission myself.

[roplusbee]

</offtopic>Where are you at in Germany? I plan on making a trip as soon as I can get some leave appoved. I have been trying to work on my ride between deployments and exercises as well.</end offtopic>

So your more recent 200sx is in not-so-good condition huh? Sounds like mine, but I got it for 1000 bucks on the lemon lot. It ran, but not well.

[ca18datsun510]

did the "vac" line lok like this red one?



if so, thats the vent tube.

[ragenasian]

Yeah that is there and his doesn't have one. Also there was some kind of vac line on the bottom of the transmission but I am not sure if it went to the transmission or somewhere else. It was a couple of years ago and I am old so who knows what it could have been. Still the fact remains the bell housing was different. Oh well. Another mystery. Maybe TMS hit on something I will have to check the title if I can find it to the wrecked 200sx and see exactly when it was made.

roplusbee:

Right now I am in Hanau Germany but in the next couple of months I will hopefully be transferred to Baumholder Germany where I recently purchased a house. By the way the 200sx runs great.

even if it was the s12 trans, the s12 bellhousing works with s13 trans and engine.

thats not it.

if its been a few years, maybe they just mixed up your trans with another.

and for the line not being on his, they tend to be missing. i actually have one trans that has a piece of folded up cardboard stuck in the hole.

[Indecisive]

another thing is that if it was the S12 transmission, it would be a few inches shorter than the S13 transmission.

I don't remember seeing that vent tube in my S12 transmission either. Its an '87, so it should be the same as the 88.

[ragenasian]

No didn't mix it up because I only had one transmission. I don't like keeping too much junk around. The only reason I kept this transmission was because I knew I would be buying another and having an extra transmission and motor is never a bad thing.

Again I wasn't there I only know that my friend (whom I trust) said that there was noticeable difference in the bellhousing. The same guy also helped me pull the motor and transmission from the blue 200 I had. Went to bolt it up to the other CA and didn't work.

No mix up in transmissions.
