Thanks to all who helped with my 'no overdrive when hot' problem. My recent fluid flush seems to not have done anything; still dropping OD when trans gets warm. Went under the car and the wiring looks ok visually, but I'm suspicious since everything is covered in dirt and oil from a past leak. After jiggling the wiring around a little bit, I still have the problem but it seems to be slightly less consistent. So I'm thinking it's a wiring problem - resistance increases to a point with heat that causes the current to not make it anymore.

I'd like to remove the solenoid and do the permanent fix in the faq, but have run into a problem. I can just access the two bolts, but despite there being a lot of oil under the car, they have rusted to a point where a 12mm wrench will slip, and I can't force an 11mm on there due to lack of clearance. Has anyone had any luck with a different technique? I'm wondering if there's a tool out there to address this problem I don't know about.....
