I recently did mine (07 SEL FWD) and its a pretty involved job. The subframe has to come out in order to remove the transmission. It can be done with some jack stands, floor jacks and a engine hoist in your driveway/garage though. As far as cost, it depends on if you’re having it rebuilt, installing a new or used one. I had mine rebuilt. The rebuild cost me $800.00 and I had about another $200.00 in fluids and a new transmission mount. If you have any specific questions, let me know. OW.
