Why 2000 is a trouble year for tranny?

[whycatone]

I thought 98 to 02 have same the same tranny, but based on some of the threads, it seem a lot of the 00 has tranny issue.

I believe what has been brought up on the board was a bad batch of one component that only affected the tranny for a short time period.

did we ever establish a manufactured date range for the affected transmissions? IIRC it was something like late 2000 models.

Probably the most comprehensive analysis to date:

nope, not enough data on the mfg date of the failures to claim any date range. In fact, there's failures that start in '99 and spill into '01. Not that I would wish this on anyone, but we need more failure data to establish a mfg date range. Toyota knows, but they ain't telling. Or, it's quite conceivable depending on the exact failure mechanism that the bad trannies are scattered throughout the range up until a part # change.

Mine is a 2001 and the tranny dropped at 112k. An interesting fact about the replacement planet set I bought. The manufacturer usually offers a 100k warranty on planet sets, but does not for the Land Cruiser in these year range. Maybe bad planning on Toyota's part for this model. I think the Tundra has the same issue for these years.
