Got a 2003 Tundra SR5 V6 3.4L that has recently taken us to from Montana to Alaska and back again. Many other trips besides that one but that was the biggie. We often tow a raft trailer behind and during the winter the camper typically comes out and we tow a single sled trailer and keep one sled in the bed.
Why I am here. Well, mostly to brag about the truck I love. But also for one very specific question. Three times in the last year and a half my A/T oil temp light has come on. Once pulling my sleds up a steep icy road in 4WD. The second time was going up a much steeper road in the spring with the camper and pulling a raft trailer. (that road was rough enough to break my passenger side leaf spring and put it into my tire, but thats a different story) and the third time was driving up a rough slightly steep dirt road for 8-10 miles.
So I checked my automatic transmission fluid and it seems to be a bit brown and smell just a bit burnt. All the forums I have read and people I have talked to have had very differing opinions. Should I flush and refill or should I just run it and leave it and wait for a tranny rebuild. Y'all be the judges. Hopefully at least a few of you tundra nerds have dealt with this before.
If your interested in what mods I've got or what I'm working on I'm happy to put in the details, but also I'm just worried about not killing my transmission and getting stranded some where sketchy.
