Do you notice anything that feels like harsh shifts when cold? With that many kms, you could have wear issues in the lockup circuit, which includes a solenoid, two valves in the VB and the clutch pak in the TC. Frankly I'd think that you'd sense it with low speed shifts. The RPM thing looks like something else. That is a CDI, did you check the fuel filter? When was that last swapped out?

Do the fuel filter first of all.
As for the tcc valves in the valve body see #'s 1 & 2

I don't think these are DIY projects in that some machining, boring is required. The solenoid should test at 2.5 ohm I believe.
Order of priority:
Fuel filter
Conductor plate
test Solenoids (these have different values FYI)
replace electrical connector while you're in there.
The valves can be bench tested with the VB out, but again, not a typical DIY.
Not a bad idea to flush the trans fluid especially if darkened in color. Should be red.
One more idea, your indy or dealer can temporarily shut the tcc off thru star. Drive and see if you see bouncing on the tach.

You managed those clips well with the channel locks. I recommend getting the proper tool off ebay. ~$25. Those clips get bent etc when working them off and on with pliers, could loosen the tension or worse cause clip failure.
If you're still bouncy on the RPMs, get the codes read before you do anything.
