How do you reset the transmisson ECM?

I know disconnecting the negative battery terminal will reset the ecm learning back to defaults. But is there a fuse anywhere I can just pull so I don't have to initialize the whole vehicle again?

Im just curious as to why you want to do this?

I have a 2 mile commute to work up and down hills in the CVNP and the trans "learns" to dump the shift from 1-2 in 2 seconds and then into overdrive asap. After about 20,000 miles it needs a reset to get back to factory default shift logic. Otherwise you are driving around in 5th gear all day.

Forgot what it is on the 4r but on my T and p/u it was the EFI fuse.

Should be disconnect battery like other Toyotas. I know my Camry was like that.
