Remove tranny without engine?

[mmasse]

I know this question was asked many times, but all answers go in the direction of recommending to.do both together.
My question is if it "can" be done and any tricks I should consider

The reason being that I have Supercarger with custom intercooler on engine bay. It would be quite a headache to disassemble everything.
I have dropped both engine and transmission together many times but would like to know if I could remove the tranny only.
From what I remember there would be two.main issues
1) clearance of shifting rod inside tunnel.
2) how to support engine on transmission side of tranny goes out

I have a 2 post lift which should.make it easier
Thanks for any guidance

You should do them both togeth...wait...blower + intercooler?

Go on...

NO. You can not pull the transmission out with the motor in place. Unless you have made a special cut at the tunnel to allow the transmission shaft to drop down and clear the tunnel.

Thank you. Clear ....$%@$$@(&

when I take my engine out of my 930 I remove the front wheels, then lower the front of the car down as low as it will go to roll the engine out. (just to roll engine out)
remove rear bumper too.
I think I have to take the air cleaner off, maybe,

Can you post some pics of the engine bay? Would love to see your intercooler supercharger set up.

Some racers have done floor pan sheet metal modifications to make it easier to remove both the engine and transmission together with less hassle - just drop it straight down. A useful modification for a race car, where you have the power train out way more often than for a sensibly driven street car. However, you would need to do more than just provide the clearance to drop the end of the shift rod straight down. You need an extra foot or so to clear the studs which connect engine and transmission, and also to get the tip of the input shaft out of the clutch and clearing the clutch. You might achieve that with a "standard" slot in the floor pan by tilting the rear of the engine down. If you have stock rubber engine mounts, they might bend enough to do that. Otherwise, you would have to remove the two rear engine carrier bolts. Now you are sPupporting both the front and rear of the engine, as well as the transmission. Maybe a tilt table would do for the engine.

Probably money ahead to avoid all this by removing engine and transmission together. For this, between your lift and a modification of this sort you shouldn't have a clearance issue.

Having done the job hundreds of times, I could not imagine even trying to pull the trans out separately. It's not a later model car where the trans tunnel is open on the bottom. And what would you gain? In a shop setting with an early car, I could have both out in about an hour.

And, once you get it out, how are you going to get the throwout bearing and arm to line up when you go back together? I only see swear words and frustration, and lots of both.

[David Inc.]

When I did my first drop I only dropped the engine at first, but when putting it back together I realized it was going to be a nightmare so dropped the trans to put it back together on the floor first, and installed both at once.

It's just easier to do it together.

seeing a pic like that makes me cringe at what people will do to these cars. race cars are different. I have said, some people should not be allowed to own a Porsche. these cars a beautiful and are getting rare due to rust and wrecks.

You JUST reminded me that's exactly what we did on my SC race car, at Watkins Glen when the guide fork in the bottom snapped off an arm! Dan J. had me go to WalMart, buy a sawzall, and away we went! When I got home I welded up a cover plate to bolt on but never had occasion to drop the tranny after that...

I agree, but it just a car. I never care what someone else will do to their cars be it a mass produced econobox or a 911. It is just a car. How many times have you seen someone take a G body 911 and "back date it" then add fiberglass fender flairs and make it a slant nose. It is their dream. And it just makes a stock 911 more valuable.

[porsche930dude]

They are not just cars they are some peoples most prize possessions and their lives revolve around them. The 911 is one of the most iconic cars in existence. High on the list of greatest things man has ever created. They will never be made again. It is effectively shortening the life of the vehicle. Every bodge on it makes it less and less appealing for a future person to repair or restore it. Weather you discard it in a week or keep it forever there will always be a future person. All because you didnt want to spend an extra hour to unbolt a few more parts.

[yelcab1]

They make a lot of these Porsche 911. It will never become unobtainable like a Ferrari 250. I really don't care what people do to their cars ... until I consider buying it and then I pass on it. There are too many of these cars around. You never have to buy one that you don't like.

It's their car. They do what they want. God bless.

Thanks Walt. I am seriously cosidering going the cut. This is a track only car. I am FAR gone from keeping it stock. And with a 993 engine with SC and track only use I will definitely be doing several 915 rebuilds, until I finally end up doing the G50 upgrade
Thank you all

[T77911S]

its just too easy to take them both out at the same time.
the sucky part I always hated and seemed to take most of my time was dealing with CV joints.

Does it just peel back by hand ?

bah humbug. they're just cars. short of wrecking the shlt out of one, there really isn't anything you can mod on these cars that can't be undone. even at that, a celette bench will cure most issues with a tub. been there, done that.

it's just metal. a material possession at the end of the day that a small group of us obsess over.

i like that mod. i do engine drops using my 2 post lift and have to get creative to angle everything on the way out as i lift the car. that would allow me to just put a pallet underneath the motor/transaxle and lift/drop the car accordingly. engine drops would be like 30-45 minutes!...

You CAN pull and replace the transmission without pulling the motor. You can do it without damaging anything. And if you are very strong you will be able to stab the transmission when it is time to reinstall it without pulling a muscle. (And it includes new and inventive curse words.)

I've done it once.
I'd never consider it again.

It is way WAY faster and way WAY easier to pull the engine and transmission together. It requires that you loosen 2 extra bolts, some hoses, and some wiring connectors. Everything about removing the engine and trans as a unit is simple and designed to be quick. You can swap out a clutch probably 4 times faster by just pulling everything out and separating the transmission where it is a simple accessible job.

[Jeff Alton]

The ease with which the engine/gearbox comeout together would make us never attempt to pull a gearbox only on a G-body car. Yes, on a 964 and newer, all the time, all day long, pull gearbox only....
