from what i know about the GSR auto's is the TCM is built into the ECU so if its going into gear but not the right one you select then its because of the pin outs, there different than the civics, what itd sugest is looking at the pins for the GSR auto shifter and CRV and you can re-pin them and it should work, I myself am swaping a B18B1 into my 92 civic DX both are OBD1 and i have the TCM but have had no help on how to do the wiring, i know some years they changed it and put the TCM into the ECU, mine came out of a 94 integra LS if you know anything please let me know, im in a bad time in life and dealing with chronic pain 24/7 and need to get my car back up and running and if i had the damn funds to do a manual swap i would but life hates me and i have to stick to the stupid auto >_> i hope this helps ^_^
