Trans Temp

I have done some searches and tried a few things but I am still showing some excessive heat but nothing noticeable with shifting. Sorry for the long post, just trying to be thorough.

Background.
2k F250 CC 4x4 204k miles, stock trans, it does have an Edge evo on it, and some minor mods (exhaust, intake, wicked wheel)
The truck is no longer used to pull anything heavy, got rid of the toy hauler. I pull a 3 rail bike trailer every once in a while, but for the most part it will have two bikes in the back, so nothing heavy.

The truck sits a lot unless I am going to the track. Coming home from the track I heard an odd sound and noticed the Edge controller flashing read with an audible alarm and showing the trans temp up around 198, out side temp was around 100. I shut it down but it did get up to about 206, checked fluids, and then let it cool off. I didn't notice anything different in the way it pulled, if it wasn't for the gauge I wouldn't have known anything.

After doing some research, I thought I might have a flow problem. So I pulled the return cooler line off the back of the trans and ran the truck for 15 seconds. I got less than an ounce through the bypass, so I assume the bypass is functioning, but I only got about 22 ounces out of the return line. According to some posts I read the return line should have pushed 32 ounces at a minimum, so I proceeded to try and isolate a flow problem. After fighting with the inlet fitting on the main radiator for a few hours I finally pulled the hose clamp off the outlet port (duh) and tested from there. I got over 50 ounces in 15 seconds, so I assumed my trans cooler was the issue and gave a good reason to put a 6.0 cooler on it.

I put the 6.0 cooler on, flushed the transmission fluid, and changed the filter (side note, the fluid and filter only had 4k miles on it and didn't look or smell burnt). After all that I took it for a test drive. Outside temp was under 70 so it took a bit but in about 30 minutes the trans temp was showing 190. I ran the flow test again and got 34 ounces from the return line, so flow doesn't seem to be an issue. I did pull the lines from every where and make sure there wasn't anything restricting flow.

Yesterday I was riding at a local track so I decided to take it out and see if anything acted up. Outside temp was 91, total distance to the track was maybe 30 miles and the trans temp got up to 181. I didn't notice any problems other than the reading on the gauge saying it was hot. On the way home it got up to 174, engine oil temp was also 174. I did notice something different though, it used to shift in to OD around 45-47 MPH depending on how hard I was pushing it. On the ride home it was shifting in to OD around 40-42 mph.

So this is where I am at, still getting hot, new fluids, new filter, new trans cooler. I have ran out of ideas, I don't want to pull it and take it to a trans shop if there anything else I can do, I don't have any connections or acquaintances that work on Ford transmissions, so I am leery of just dropping it off, it being something simple, and I end up with large bill.

Thanks for taking the time to read my ramblings, any suggestions would be much appreciated.

That's not too hot if your hauling a load up a hill. I've hit 220 at times.

I believe 240 is the recommended max. I had a list of max temps for lubes on our trucks I'll see if I can find it again.

thanks for the replies, the temp was still slowly creeping up when I shut it down. I understand on a hot day pulling heavy loads I can see over 200, but this was flat terrain with two bikes and gear in the bed (maybe 600 lbs tops), and I don't drive it hard.

I would expect 170 or less for how I drive/haul these days. I was hoping to see a consistent 150-160 after changing to a 6.0 cooler, it just took longer to get hot (what I consider hot). In the time I have owned it, it has never hit 200, hauling anything, now I can hit 200 driving around. I guess I will just have to take it in and taking a beating at the trans shop.

If a site admin reads this, please move this to transmission problems
