I need suggestions for better transmission cooling.
96 1KZ-TE with A343F AT.

It could be that the oil in your viscous fan has degraded . It seems to be the most common reason for overheating. If it has never been done it definitely needs doing . Refill with new oil at replace fan. Cheers

I meant replace the oil or get a new viscous coupling for the fan

Install trans cooler before the radiator.

Are your hoses in/out of the BM cooler on top? No chance its somehow got an airlock?

My thinking here is that as your ATF goes through the heat exchanger at the bottom of the rad, it is not cooled as you are already running hot. When crawling uphill

I think you are right, and I also so a lot of differing opinions on where to place the cooler.

My temp sensor is in the flex hose coming off the trans outlet pipe.
