Hey guys. Here are some pictures for you members that may need to replace their IS250 RWD transmission. My friend and I completed this in our garage. We spent time on it after we got off of work. I think it took a total of 20 hrs combined. We got a transmission off car-part-com for $850 shipped. Shifts so smoothly!
Keep in mind: we are both in the health care field; not mechanics. So if we can do it, you can too!
The car was jacked up and supported with 4 jack stands. The front jack stands were positioned higher than the rear stands. 2 wheels were put under the front wheels for safety as well. The front was up about 21 inches and the rear about 15 inches:

The starter has two 12mm bolts holding the nuts in. Remove those, remove the 2 14mm bolts that hold the starter in, and the starter will be free:

Before you remove the passenger-side header, you must remove the intake, oil dipstick, wiring harness to the front two coil packs, and vacuum hoses by the shock tower.

Undo the bolts that connect the flywheel to the torque-converter. There are six 14mm 11-grade bolts. They are held on really tight. Make sure you hold the crankshaft in place when you remove these or the entire flywheel/torque converter assembly will move.

When the new transmission lines up this pin will help with the process. You can adjust the torque converter to line up with the flywheel by sticking a hand into the starter hole, reaching back there and moving it.
Reinstall in reverse. Good luck! Thanks for looking.
P.S: These pictures should also help a member that may wanna just install headers or an exhaust.
