CA installed, can't back up!!

[btustison]

I spent the last 4 days laboring away in my tiny, cramped garage and I finally got most of it done (still need new P/S line). My car was the grimiest vehicle I have ever worked on, I spent half a day cleaning the thing, on top of that the chassis is not straight, and of course it is a 89 which means more work... anyway I fired it up and went to back out of the garage when I learned the hard way that my transmission won't go into reverse Needless to say I am pretty bummed out right now, if anyone has a spare transmission in Washington State I am looking for one.

Before you dam the transmisiion, the gears may have been knocked out of whack in shipment. It has hapened to me twice where reverse gets hungup halfway. Put the car in neatral to push it out and drive it around for a while, reverse should come back after a a little bit. Of you could split the case and move the gear back into place yourself.

Or, if worse comes to worse, swap your KA transmission onto the CA bellhousing...

Does this mean for me that I can convert my FWD to a RWD by just taking a KA transmission, sticking a CA bell housing on it and mounting it back up? I know I would need a diff, drive shaft, and all the extra's, but it sure would be origina;!

LOL, it's a lot more complicated than that. You would have to weld in a different rear subframe to mount the diff, hammer out a transmission tunnel and driveshaft tunnel, probably a fuel cell since your gas tank won't fit, cut a hole in your center console for the shifter assembly, fab up some mounts for the motor, and a BUNCH of other stuff that would make the project damn near impossible... or at least totally unfeasable,

I think its feasible, just because it would be cool and I'm not the one who would have to do all the work. DO IT.

as for the reverse, that sucks... I once installed a transmission onto my 240 that only went into third gear and had no neutral, if that makes you feel any better.

Wish my swap looked that clean

O wait, it did a year ago when I first did it LOL. Good luck on your transmission prob mate!

That'd be my vote, just swap the KA transmission box into the CA bellhousing.

Drove it around today and still no reverse. My mechanic/dyno shop told me that it is probably the reverse lockout device malfunctioning, and that it is repairable. Aren't the KA and CA gear ratios different, because the ka is torque with no top end and the CA is torque-less untill you hit boost...

The car was a lot more fun to drive though, until my old KA radiator blew up... so much for a clean engine bay.

gear ratios are the same. Only the SR has a different 5th gear....

It's the final drive ratio of the diff that is different, the CA powered cars came with a 4.36, the KA (and SR) are like 4.08

Course if you are using your stock KA diff then it really wouldn't matter..

5th gear is different too.. but then again it's the fuel economy gear so you won't/shouldn't do much racing with it

I drove my buddy's KA24E powered 240sx and he drove my CA powered silvia and we both agreed it felt like the Silvia had more bottom end. (Thanks to the 4.36 final drive, and probably due to mine having 130,000 less km than his..)

Just a follow up, it was the reverse lockout stuck in place. All I had to do was remove the sort of oval plate on the tailhousing and swap it for the one out of my KA transmission.

and just to inform; 1st-4th are the same on KA vs. CA, 5th is different, and so is the rear end.
