Just ran into this too. 2003 Rav4 1AZ-FE U140F AWD. My VIN wasn't on the list, so Toyota didn't send me nothing, and there are no recalls. Thanks a lot Toyota. But it's the same problem. P0750 code. Intermittent transmission shift problems. Long story... ended up replacing the ECM with a refurb. it now seems to be fine during a 40 mile test drive. Whatever the transmission was doing wasnt like anything other folks experienced. Really freaky and dangerous. Cost me $500 to figure this out and fix it.
