p0745 & p0795 again

So I'm getting these two codes on my 00' 3.0 and I go ahead and replace the solenoid pack.. I pick her back up and it's driving fine for about 10 miles and guess what? Another gearbox fault of p0745 & P0795....
Could the cause be a few broken valve springs or is my tranny on the way to being totally rebuilt?

I guess you have already seen TDC's thread in the FAQ's on the 4-3 spring replacement?
Other than that the best I can do is wish you good luck!

Once I get up to 4th, say around 45-50 mph, and have to come back down it's getting stuck in the incorrect gear and I get the gearbox fault and p0745. If I get up to 5th, say around 70-80 mph range, I get both p0745 and p0795 along with the gearbox fault message. My scanner says solenoid A and C. Shop scanner says incorrect gear gear ratio 4th (p0734) and 5th (p0735).

From what I'm seeing the extra info for p0745 is saying:
Pressure control solenoid 1drive circuit: short
circuit to ground; open circuit
Pressure control solenoid 1 failure
And it's the same thing for p0795 except it's solenoid 3 instead of 1.
The p0734/5 will be set when the aforementioned codes are present and ABS/TRACC will be inhibited...I guess this explains why my ABS and TRAC light are on...
I've replaced my solenoid pack so should I be looking for a short somewhere as my next logical step?

Could be a bad connector or chafed harness. Which might be a pain to find. (Sorry!) I don't know where it runs or even whether it would be reasonably easy to route another (DIY replacement) harness.
The full jag diags can read signals I understand and if it's loose enough I guess it would be possible to read them while wiggling wiring.
I suppose it also could be some internal (to trans) short or damage.
If you can disconnect the wiring I suppose you could end-to-end test it while wiggling as best you can. Maybe...
