So far the transmission is perfectly sound.....knock on wood. At 188,000 or so I did a partial fluid drain. Just draining the fluid and re-filling with Royal Purple. I did not drop the pan or change the filter. I was thinking it might be time to do the same. When drove to Boise I had the X pretty loaded down and with the boxes on top it felt like a wind sail. I was only getting 16.3 mpg. And we climbed alot of mountains. I crossed my mind that maybe the transmission would give out.
I think the key for the transmission last so long, is just drive the hell out of it. But thats just my opinion. I will rebuild it like SwissFrank did when it does give out.
