Hey
OK I have a 97 900 se turbo auto and I wanted to find out how difficult it would be to do a manual swap. First has anyone else tried this? secondly would I have to use another 900 transmission or could i get a honda tranny or something that would probably be less expensive and just make a adapter plate? thirdly can this be done in a weekend or is this a longer project. Thanx a lot

well I like the auto a bunch, however I was kinda looking to for change and a project to have over the winter. I have always wanted a 5-speed but I don't feel like buying a new car. I love the convience of having the auto but I would enjoy the envolvment of the 5-speed.

There's a few things to consider when doing this. I'll list them:

1) You would need to use a NG900 manual gearbox.
2) Of course you'd need to use a NG900 linkage and clutch system.
3) Im not quite sure if the ECU would plug right up, but you'd need an ECU off the same year of a manual NG900.
4) Once again im not quiet sure, but you may need new axles and the corresponding parts to implement them to the new gearbox.

So basically...yes it could be done. In a weekend...probably not, unless you had VERY good help from an extrememly knowledgable mechanic. Could be interesting to see this done, but I definately wouldn't do it on your Saab if its your main source of transportation.

Also keep in mind...the NG900 gearbox isn't all that. Its somewhat known for having synchronizer problems and sometimes seizing up.

Don't do it....It's possible on the C900, but the NG is an entirely different animal. The slushbox has excellent pickup, but it sucks on the open road. It has a low final gear ratio, so your gas mileage is anywhere from 4-8 mpg lower. (Ignore the bullshiat EPA ratings.....)

I'd stay with what you have, or if you REALLY want a manual, try to sell the auto. The conversion is a headache to the nth power....

Real lotta work. Definetly not a weekend job.
It's definetly possible though. If you really wanna do it, the best way is to get a wrecked/blown up car that will have every piece that you will need for the conversion.
Good luck

Well, if you have you heart set on this, you are in luck because the project Wasaabi car is converting to a 9-3SS transmission and shifter. So, the complete setup (e.g., transmission, shifter, linkage, old style cable clutch pedal) are together. However, I have done this on other cars and it does take some time. Probably not a weekend, but doable. It is not rocket science, you just need to put together a list and ensure that all the parts are on hand before you begin. If you are looking for a project, this will keep you busy and you will get the satisfaction of doing it yourself. However, if you are considering this just because you want a 5 speed, sell or exchange the car for one you want.

The bell housing from a NG900 was put on the transmission so that we can match the two up. Once I get it, I can share more details.
