It might be an RH in which case it's mostly (or all) hydraulically controlled, the RE is electronically controlled. Did you drive the donor vehicle? If it was shifting fine no adjustments should be needed. IMO i would reseal the whole transmission just to do it.
Yes I rode in the doner vehicle. It shifted fine but the shifts we very smooth. I couldn’t tell if they were smooth or loose as I was on a gravel road for the test...overall I’m very pleased with what I see.
