High tranny temp- imagine that
I have a Perma-Cool tran filter relocation kit with a gauge and bypassed the radiator/tranny cooler with a external 8"x12" cooler mounted in front of the radiator. I am getting a reading of about 200 on hard driving isnt that too high? Mounted on the drivers side by the lines. I dont think it is stable but I was looking for input.
I didnt install the cooler, but I did install the perma-cool to replace a magnetic filter POS...

Your set up sounds similar to mine and the only way I see 200* is when accelerating up a windy hill on a hot day.
While cruising on the highway with my TC locked, I run about 60*-70* above the air temperature.

A local SVXr , not YET on The Network, was showing 208°f, untill he pulled and flushed his trans cooler lines, and THEN showed about 176°f on a similar heat/humidity day.

I was having a similar problem on michael blues car when I dropped it off to him. He has a brand new radiator I just installed plus a aftermarket trans. cooler and perma cool filter with gauge and it ran at 200-205 the whole trip there and climbed to nearly 230 when he was test driving it hard. The tranny, Most of the lines, internal filter, radiator, and external filter are all new and the only thing left old is the external cooler which was already there but was hooked up wrong, Which I corrected. Why is it running so hot?

Frequent stops really raise the ATF temp.

I have the following set up for over a year now. While pushing hard and accelerating up a two mile hill with many sharp turns my temp's will reach 100* over ambient. While cruising on the highway with the TC locked it is like I said earlier about 60* above ambient. If I can get on the highway without first heating up the ATF, then it stays closer to 50* over ambient. Also as you will see, I am measuring the temperature of the fluid immediately after it leaves the trans, I'm guessing this is the "high" spot on the temperature path???
- Transmission to black steel "T" fitting with temperature sender. I used 1/2" npt fittings to minimize restricting the flow. - I removed the metal lines that run under the head, and have rubber lines running the whole way. I'm not sure if the fluid picks up any heat while running through metal lines attached to the head, but I assumed that it did and eliminated them. This also make installation easier. - From the sender the fluid goes to a Perma-Cool Filter #10678, I have this mounted in the area of the original filter, along the frame rail, below the battery. - From the filter I bypass the stock cooler and the line goes to a B&M #70255 16,000 gvw, 9800 BTU cooler. I have the cooler mounted in front of condenser. It fits vertically between the rad supports. There is room for another identical filter on the other side. - The line then returns to the transmission. It appears that my cooler is much smaller than yours, but the temperatures are about the same. My first guess to explain this is my placement in front of the condenser. If I take the car to the Dragon this year, I plan to get an identical cooler and run with both installed. When I do this, I will also change the set up to include the stock cooler in the radiator, during the winter I had issues with the temperatures being too low while on the highway resulting in the TC unlocking. I'm not sure if I will plumb them parallel, in series or a combination? I also want to put a second temperature sender in the line just before it returns to the trans, then I can actually see what the cooler(s) are doing. I got the parts from Jegs, but they are available from many places... Or I may just put in a 5-speed?????

Synthetic ATF
If you havent already do so now. Amsoil Synthetic ATF is what you need. Its great stuff, over 300k miles in my AT AWD Legacy Wagon on it, and still shifts perfect. Nuff said.

And without using $8 a quart unverified by independent lab fluid in there for 256k you can now actually pay for the rebuild.
