@mrvedit take this down if if violated some sponsor rules. (I'm not trying to sell them here right now!) But I have been considering getting some separator plates cut for the 60e that will do quite alot for the home builder and pro alike. I plan for it to do the following:
-Engage the overrun clutch anytime in D3. All gears. No need for the sonnax HD 2-3 Shift valve
-Block the 4th accumulator. I've found this to be a VERY good upgrade on any performance build
-Make the TCC on/off only.
-correct shift timing with proper orifice dimensions
Yes, it will just take a separator plate to do that stuff. (You'll still need to fix all of the leaks that are inherent to the valve body, but the separator plate would be an easy bolt-on upgrade for any trans build
Is that something guys would be interested in? @bbond105 @vorteciroc @98CayenneT/A @PBA etc etc there's loads of guys I could tag so don't feel left out if I didn't write ya down

Decided not worth my time/effort
I have some separator plates cut that I use for myself
But I have no desire anymore to try to match orifice sizing for the variety of builds that are out there.
The overrun feed bit is not too hard. You can feed the overruns straight from D3 without the need for the sonnax valve or anything other than a plate change.
You can actually do this on a stock plate if you can use a piece of lead to block one hole and drill another in a precise location
.
4th accum can be done with setscrew but can also still be done in the plate...block 33b...still omit piston and spring so lube reaches the control orifice
I did some testing and the TCC can be made much closer to on/off with just a sep plate change. It will do the same as setting the tune to 100% duty cycle
but I found in testing that just locking the valve out was still the better method in my opinion because even 100% duty cycle isn't as keeping the valve outboard like you do if you lock it out.
so...short answer is YES it can be done. Long answer is that NO i didn't want to deal with 100 emails a day about orifice sizing and people that put a simple separator plate on a trans that was already cooked then being expected to spend an hour diagnosing their 150k mile pile of **** that doesn't work

@bbond105
Exhibit A is in that thread. Dana must have WAY more patience than I do putting together custom tailored kits for people
I have no desire to put together **** for guys that seem impossible to please like what you see in that thread
