FJ62 Tranny Problem

[surower]

When I drive my truck for more than 30 minutes, the tranny (automatic) doesn't want to shift. Anyone run into this problem?

Use the advanced search feature, and search for "A440F" in this section (60s section). Lots of threads that detail what you can do to the tranny to massage it back to proper function.
