I noticed a hard shift into reverse, then under load it acted like it went into neutral a couple of times. I saw the info above about the tsb and took it to the dealer. For 4 days I got the "we can't find a problem" bit. I called toyota cust serv several times and finally got a case number. Voila, they found a problem and have an ecu on order. There hasn't been an MIL light, so hopefully no tranny damage, but if there is, they will see alot of me until it's replaced. 02/92k miles. I never did get a letter either.
