Small mistake with 4t65e TransGo Shift kit

I recently installed a shift kit in my 2007 Monte Carlo LS, After installing the kit I realized I left out the .530 spacer that go on top of the 2-3 accumulator piston. Everything else however was installed including the long .750 spacers. Will this damage my transmission if I left it like this or is it recommended to drop the pan again to install the .530 spacer?
 
The spacers are there to reduce accumulation & speed up the shift time, Specifically the 2-3 shift in this case.
These kits are designed around all the parts working together.

Do you have a scan tool capable of reading Shift Error Times & TAP Cells (Transmission Adaptive Pressure)?
 
Unfortunately I don’t have a scan tool good enough to detect those 😅. I did drive it and it does seems 2-3 shift is more drawn out and that I have to apply more throttle to get it to shift again, it won’t shift again until it reaches 40mph. On WOT from 25-30mph it shifts very hard into gear, hard enough to chirp the tires😬. I honestly might drop the accumulator again to put the spacer .530 on top of 2-3.
