Total NEWBIE here so please be patient with me We are looking at either 2018 or 2019/2020 Sienna XLEs and I've seen as we research that possibly the 2017/2018 have finicky transmissions. Do the 2019/2020 transmissions differ at all? I don't mind an older car if the only difference is Apple Play. This will be my vehicle for a LONG time so trying to make a very informed decision. Thanks for any input!!!
