Just wondering if it would cause any peoblems to use the transaxle as a lift point for the jack?

i do it all the time- dont leave it on there too long but theres a big brace it bolts to at the top so its strong enough.

I wouldn't do it

why? ever had one apart and looked at what its made of. Ever jacked one up by there? Any actual date as to why not?

I split a trans doing it once. Cracked it good.

It HANGS by two skinny bolts that go thru the rubber mount. Your just asking for trouble.

you have to be careful where you put the jack- should be a wide jack and should be right under the fat part of the case- it pins the rubber mount between the case and the upper brace-have never had a problem and my mounts still look fine- i only do this when i need just the rear wheels up to place stands though, i dont leave it on there long. Ideally you would only want to use jack points though.

It is tempting, but after looking at what connects it to the car I don't think it's a good idea.

Having just had mine down and seeing what holds it there I would NEVER want all that weight on those smallish bolts!

I've done it to place jackstands before.

I do it all the time to place jackstands. I use the point where the TA attaches to the torque tube and a wider cradle on the jack. I've done this for over 3 years with no problems yet.

But I would be afraid of bending those two bolt -- they are already hard enough to get at if you ever have to remove the tranny. I'd choose a different point before using the tranny.

when jacking the trans up, it does not place any pressure on those bolts- it pins the cage for the mount between the case and the brace on the frame.

It looks like the easiest place to lift the car quickly, so I tried it. It seemed to work fine. The tranaxle does move up a little before the car starts to lift, but I don't think it's a big deal.

Yep, Im pretty sure the rubber mount collapses enough, so that you have solid contact between the case/alum mounting block and the mount body.

Regardless, I recall those two bolts are M8 (8mm), so they have a cross sectional area of 0.078 sq. in. each. If the back half of the car weighs 1500 pounds, that is approx 9600 psi shear stress on each of those bolts (if they are loose). Proof strength for a SAE Grade 5 (very similar to DIN 8.8) is approx 70,000 psi. For a static loading, they will not bend or break.

The only concern with this jacking method, would be possibly damaging a very old/brittle rubber mount.

But with that said, I have jacked the rear of 944s using a 2x4 as a jack pad under the trans for years.
