Hey all,
I have a 03 Civic Hybrid with most likely battery and inverter not working. I just found a 2005 for parts. Can i swap all the electronics for the hybrid system/battery from behind the seat into the 2003 and it work?

Also for future proof, does the 2005 Civic Hybrid tranny work to replace the 2003 civic hybrid's tranny if it ever goes bad? Or is it not compatible bc its a newer tranny in an older model?

I've tried looking everywhere online for these answers and havent been able to find any. Any help is appreciated. Plan to transplant good parts in the place of broken parts.
