replacing m6 tranny mount, help please

[grandkodiak]

im gunna attempt to swap out the tranny mount on my 96 lt1 m6er... was wondering, wheres the best place to jack the tranny to hold it up? the car wont be on a lift so...

also, anyone know the torque for the bolts on the mount? i already have the crossmember specs from another post.

make it easy on me, can someone just literally circle where i should jack lol... ive heard tailshaft but i dont know exactly where that refers too, i can guess, but i dont do such things when it comes to anything mechanical.



edit i found 38ftlbs as the tranmission mount bolt and 77lbs as the trannymount nut but its from an 00 ls1 car w t56... i take it its the same for the lt1/t56 combo since its the same frame anyhow?

see where the driveshaft connects to the trans, thats what they are referring to.

you could also use a block of wood and lift it under the pan.

dont read too far into that pic... its an a4 lol

you can use the block of wood method, or a trans jack pretty much anywhere along the t56 case, its a quick job so just make sure you arent resting it on any sensors or plugs...

hippy fail. mike nailed it dead on....






thats a better idea of the trans he's gonna be working with. lots of nice stable spaces to get up under.

[grandkodiak]

lol i know i know... its the only pic i could find that was close to being relevant via google

[Mike]

if you can get the jack in without the handle being in the way, the flat spot about 4 inches in front of the trans mount is a good spot

[grandkodiak]

good call cbr...

now the simpler question... where are good jack points and jack stand points from the rear? i cant get the jack under the 2 front "shoe" spots but i can get easy access from the rear of the car, i just dont remember where to jack and where to put the stands from when bigal helped me with the rear sway bar.

[Mike]

easiest thing would be to jack it up from the pumpkin

[grandkodiak]

then where do i put the stands to hold her up? i was thinkin the sway bar points but they look brass and flimsy for a 3400lbs load

[Mike]

right in front of the lower control arm mounts on the chassis



if you have subframe connectors you can put them anywhere along them

[grandkodiak]

yea so...got the trans up as far as the jack could take it, and i could barely slide under. guess im gunna bite the bullet and resign the job to a garage. why is nothing simple?

You could barely slide under the car? If that's the case, just get higher jackstands. Would be cheaper than going to a garage.

Small jack, small block of wood, right ...

........... here ^^^ on the trans.........


That looks more like my 77 than a 4th gen.


go find a nice 20% harbor freight coupon and go get some nice jackstands.

yeah thats a good call, and if you have gotten any magazines in the last few months, you probably have good coupons. they have been putting them in everything from gmhightech to maxim

if you dont have a h/f near you there is one in ewing

I'll do it for you if you honestly think bringing it to a garage is easier.

Brian...ugh
the reason he cant get under it is because he has what amount to be a minor upgrade over a sissor jack to jack the car up. Im surprised he got the car high enough to put the stands under it.
Get a better jack, jackass. We sell them. Isle 5 and right in front of the store.
