My FJ62 has 315k miles on what I believe is the original tranmission (not entirely sure, though). A few thousand miles ago I did a very thorough flush, added a cooler and temp gauge. I'm fairly certain my lockup is not engaging, as trans temp gradually climbs when cruising on the highway at 70+mph. Otherwise the trans seems to work well.
Any suggestions on getting the T/C lockup working again that don't involve replacement?
