I have a '99 XE V6 4x4. Last winter, the output shaft and rear planet stripped in the transmission. I rebuilt it and it has worked now for about 12,000 miles. However, lately it has been acting up pretty badly, especially in 4th gear. Some heavy vibration at highway speeds that I know is from the transmission because when I force it into third, they stop. Anyways, I'm getting prepared for when it dies. I know that I have the RE4R01A trans. Wikipedia says the RE4R01A is in a long list of cars (https://en.wikipedia.org/wiki/Jatco_4R01_transmission). I plan on looking for a low mileage wreck and pull the transmission from that. I wondered if anyone had any inputs on which cars would be the best because there seems to be a shortage of Frontiers in my area (Eastern Ky). Thanks in advance.
