06REDSS/SC

Anyone know how to Split the Transmission from the Bellhousing. I have taken every bolt holding the two together out, and tryed prying it apart i moves approx. 1/4 inch, then when i took the pry bar out it snaps back together like there is something inside holding it together still.

I am trying to replace the Bellhousing, because it is cracked where it bolts to the front tranny mount. I already have the new bellhousing.

Did you make sure to unbolt and remove the intermediate axle shaft that runs along the back of the block?

Other than that, get a bigger prybar, or start wiggling and pulling at the same time. Just be ready to catch when it breaks loose. As long as nothing is still connected it should just fall out.

you need to pull the gears off the end of thee tranny... if you take the cap off (towards drivers side) there are I think three gears you need to pull to take the casing apart...

I pulled that cap off of there, but i didn't see any way of taking those gears off.

I don't see a bell housing in the manual, it looks like it is part of the transmission. Here is the clutch install procedure. Sorry if this isn't what you need, but I am a body man, not a mechanic and I don't know how to find some of this stuff in Service Information.

Wrong, the SS\SC does not have a getrag.

Sorry, I have a 2.4 with automatic.
Here is the MU3
None of this really looks like what 06REDSS/SC is looking for, but maybe it will help. I can't find trans disassembly in SI.

Me too, rebuilding a total that had a cracked bellhousing where it mounts up front to the engine cradle.

06REDSS/SC

so, i found out that the trans has to be completely disassembled, meaning all the gears and everything just to change the damn bellhousing.
