Replacing clutch - anything else to do at same time?

[Pragueprado Junior Member Find all posts View Profile Close Pragueprado]

My 2003 1KD has almost 250.000km - the clutch is starting to slip in the higher gears if you give it too much torque at the wrong moment. While it could go another 20k or more km on the current clutch with careful handling, I'm going to go ahead and have it changed (with the original Aisin).

I wanted to ask everyone if there's anything else they'd do, service-related or preventative, while replacing the clutch. Rear main seal, for example?

Thanks for any input.

Yep, Thrust Bearing, Main seal and any core plugs that may be hiding in there, to name a few.

The kit came with the thrust bearing. Can I be a novice and ask what the core plugs are? Any part number you can refer me to?
Thanks,
