I'm loving my T4R TE, but am somewhat annoyed about the limitations of ATRAC & the locking rear diff. Specifically, you must be in 4L to use either of them, and to use them together you must be going < 4 mph. That's fine for rock crawling, but not much help in mud or sand. There are a number of mods posted on other boards to get around these same issues with Tacomas and FJ's. Has anyone had tried these mods on the T4R? Armed with the 2010 TE wiring diagrams, I hope to experiment in the coming weeks.
