What is your transmission temperature?
Hello, I have a 95 auto and I want to know what the trans temp should be
Yesterday I drove 2 hours on the interstate between 70-80 mph and my trans got up to 224 degrees and held there.
Normal for these cars?
Coolant was around 212 and oil was 230.
90 degrees out with the AC full blast.
The transmission gets appropriate fluid & filter changes

It's usually 10-15 degrees warmer than the water at cruise because of the trans cooler inside the radiator. Your temps could be okay tho a bit high for my liking. I would look to be sure the radiator and condenser is clear of debris (especially between them).

I swapped out my radiator for a Griffin Racing one that doesn't have any provision for trans cooling. So I used an external one inch thick plate cooler that I pulled off of a one ton Ford. It's about six inches tall and as wide as the radiator is. I mounted it right in front of the radiator with a bracket I fabbed. The highest temp on my data log so far has been 180 deg.

The trans cooler is in the cold side of the radiator, so while there is a correlation between coolant temperature and trans temperature, it isn't linear because heat load being shed to the radiator varies with operating conditions and ambient temps. Ie, in winter conditions the radiator cold side coolant temperature will be near ambient. In summer conditions, cold side temp will be much higher. This affects transmission temperature.

Running a B&M stacked plate cooler in front of radiator (directly, not through radiator 1st). I have an aluminum transmission pan with a temp sender in it and even after running around for an hour I barely will see 150 on the auto meter gauge....just for reference...
