Auto Trans Temp

I've run both Transynd and Dexron-III in my stuff. Running it in the PG with the 6 cylinder, the Transynd took longer to gain temp, but held the temp longer after shutting the car down. The dexron-III gained temp faster, but cooled down faster as well (No trans cooler mind due). As far as converter flash, it was maybe 100 rpm higher with the dex-III at most. E.T wise, the car preferred the dex-III by .02-.03. In a v8 car I would think there would be less difference. I've been more keen to running non-synthetic trans fluid. Whether it makes a difference or not, it depends who you ask.

I have never had a transmission temp gauge and have never ran any kind of cooler. I have never had any heat related issues with my transmissions. The glide has well over 500 passes and looked like new when I took it apart the last time. Now running a 350.
