I'm noticing that after I drive a bit and warmup the transmission, a shudder begins between the shift between gears 2 and 3. Based on the TSB and the known culprit being solenoid #5, does it hurt to ignore this problem or am I damaging something?

I see a TSB on this:

Automatic transmission, shudder during upshift
Background
This Service Bulletin describes the fault tracing and corrective action for transmission shudder during upshift (most common during the 2-3 shift). If necessary refer to the methods in VADIS. To replace the line pressure solenoid (5TH solenoid) an updated method can be found in this Service Bulletin.
