FJ62 Transmision Oil Idiot Light questions and advice

[Wile E Coyote]

Sorry to hijack but any advice if my tranny light comes on when I start my rig and never goes off? the same with my e-brake light.

Bad alt (or VR, but same result= new alt)

The transmision seems to change gears much more smoothly now, from park, to reverse, to drive the is not any heavy jerking and it seems to run well. I'm going to drive it on the high for 120 miles or so, then have the fluid changed again to be sure and a transmision cooler installed.

Thank you all for your help. I've been looking around on the threads and see that several coolers are recomended. Does anyone have experience with them and if so, is one better than the other?

Thank you again!
