Well I am looking to remove my gearbox and take it to sharktoberfest for Mark to fix. Any hints or help would be greatly appreciated.

You are going to need a transmission jack- its pretty heavy. There are some posts of removing the trans if you do search.

^^^Pretty much necessary.

And a 4X8 sheet of blue styrofoam on which to lie.

You will most likely need to "lift" the entire car off the ground as you will need to remove the exhaust system, loosen and remove torque tube bolts and the like. I was able to lift my car about 20" all the way around and it made a vast difference on access.....it is certainly not a simple job and whatever you can do to assist yourself in access to the various buried fittings, bolts, etc will pay dividends....other little tips like loosen the nuts on the axles while on the ground will become apparent after you put it in the air. I was able to manuver mine around pretty well with just a floor jack, but I did remove the entire rear suspension. The transmission/diff alone is 200+/- pounds as I best recall....a fairly nasty chunk to manhandle about....

Removing a trans on your back presents an interesting but not impossible challenge to a good surgeon. Of cours questions will be asked about how it got there to begin with, and why automatics seem to flourish as parasites much better than manuals.

Or you could just throw a cape over it and pretend it isn't there, Igor.

I found myself wondering if any of the 928 design engineers happen to have any married parents, and if so, were they married to each other? Fairly doubtful...of course I do wonder that frequently....just about anytime I elect to do a "simple job" on mine....

They write songs about those kind of problems. Like the guy who came from Alabama with a banjo on his knee.

I've done this. You can use regular floor jacks to lower it, but a trans jack does give you better control. Make sure you have some nice tall jack stands so the car will sit high enough for you to get it out. Also make sure you park the car nose in - so you have room to pull it out. Other than that, just start taking things apart.

Be very careful NOT to let the trans hang on the driveshaft only......you can break the input shaft on the trans , which is 5 th gear !

I was going to mention you should have a chain with a couple master links to hold the trans up.

I use heavy nylon strap (motorcycle type) tiedowns to hold the tranny up. It's much easier than chain, because you can easliy adjust the height. You can pull it up tight when installing the suspension. I found that unless you have friggin huge jack stands, the transmission attachments won't work with a standard floor jack, and the transmission jacks seem flimsy. I ended up cutting a 3/4" thick x oil pan sized piece of plywood to use as a platform for a standard large size floor jack. I handled eveything by myself. The only time I felt a little overwhelmed was when pulling and reinstalling the exhaust alone. I utilized cardboard (for sliding the exhaust around on), jack stands for positioning the exhaust while preparing to start bolts, and FEET to lift and lower the exhaust as a whole onto the jack stands... I highly recommend an assistant. I sure hope no body watched me wrestling the exhaust around like that.... You can put the wheels back on the suspension to wheel it around easier if you need to before re assembly.

After completeing a transmission swap on your back, you will discover 3 things.

1. Everything else will seem easy in comparison.
2. Arms and back get really sore (you're old)
3. You will start dreaming of buying a lift.

If you leave the outer axles attached, which I recommend, the whole crossmember / hub / axle apparatus will want to topple backwards towards the rear of the car as you lower it and the shocks/springs clear the body. Best to have a person on each hub balancing it.

Its top heavy and wants to lean back.

Car has to be high.

There is a really good expanation as to how to do this somewhere, not on this forum, but on the internet somewhere. Sorry can't remember where.

Basicly the idea was to release the rear shocker/ spring assembly allow the cross member and suspension to swing down leaving the front suspn. mount/pivot in place. use a ratchet strap or similar around the G/box to lower and control. I can't remember everything but it is possible, I've done it. Fuel tank stays in place, torque tube stays in place, exhaust comes off. Sorry can't remember more, was several years ago now.

Good Luck Roy

That's exactly right for the 5 speed.

For an auto, I like to take it out with TT attached.

I remember asking this same question a while back. Here's the link to the thread. Greg Brown offered some advice a few replies down. It's how I ended up doing the job.
