I’ve done some googling, but haven’t found a definitive answer yet.
What rpm should the car be sitting at when doing 100kph on flat road. I’m at 2000prm.
I believe I have the 545rfe- so 2 overdrive gears.
Somewhere around 90kph I feel like it shifts from 4-5, then just over 100 I think the TC locks up, which allows revs to be 2000 at 100kph. Is this all correct? These are indicated figures, rather than gps.
Thanks in advance for any confirmations/advice.

First of all, welcome to the forum!
My 2006 tends to lock up at about 80km/hr.
There is sometines a change at about 90km/hr.
If you are not driving like you stole it, you can slow to 80km/hr with it staying in top.
At 100km/hr mine is doing about 1800rpm.
I hardly ever use the OD lock out. It does alter the change points.
If the MIL light comes on for a trans fault it doesnt lock up and at 100km/hr its doing around 2500rpm.
Its easy to tell if the lock up is on as without it the RPM will go up & down as you put your foot down or off.
These trans like to be over filled with fluid. You could try adding 2 ltrs and see what happens. It wont hurt.
If it hasnt had trans fluid/filters changed in the past 50,000km, it would not hurt to do it. Use silicone to reseal the pan. There are 2 filters, the usual trans type filter (make sure you get the right one) and one that looks like an engine oil filter.
How many km has it done? Has the timeing belt been changed? There is plenty of good information on lostjeeps.com Many KJ CRD owners on here are also there. These engines can have valve failure at about 250 -300,000km.
When running right they are great jeeps.
