I got the truck back today and it's awesome! Just really happy to be out of that honda civic! One question though...I hooked up my tranny temp gauge, and when test driving the truck, the gauge wouldnt go above the 100 degree mark, which is what it starts on...I didnt drive it for that long, maybe 20 minutes or so. Is it possible that with it being cold outside, new fluid and a clean and flushed system the fluid isnt even getting over 100 degrees? I will be back on the highway with it sunday, so we'll see than, but I was wondering if anyone has some common temps they can tell me. Thanks.

it depends on where your probe is. mine is in my hotline so I can see temps coming right out of the converter. The probe in the pan can be deceiving as your getting temps after the fluid has gone through the coolers. If thats where your probe is then it will take a while to build up heat to there. Even with my probe I see driving temps of 130-145 only time it gets above that is when the converter is not locked

Ok, thanks. My probe is in the rear pressure test port. I read that the test port temps are usually around 20-30 degrees hotter than in pan readings, and generally in pan readings are 60-80 degrees above ambient temperature, so if its 15 degrees here now, than under light driving and short distance, my temp should be around 95-100 degrees or so....Like I said, I will have it out on the highway for a few hundred miles again tomorrow, so I'll see what it does.

I was going to put it in the pan, but the place that did my tranny said they would rather put it in the test port than drill the stock pan...I would have sprung for a deep pan with port, but after $3000 of unexpected tranny bills, I was kind of limited...I think when I have the $$ I will get a deep pan, put the probe in there, and seal off the test port again...anyway, that will be a few months down the road, so I'll see how this works out for now. Thanks guys.

I wouldn't worry too much about your temp it's just interesting where the temp gauge is at. It should be fairly accurate.

I've seen people try and make their own drain plug and/or temp probe in stock pans it doesn't work to well. So you did the right thing.


In the future if you want make a interesting,informative thread. Get one of those pans with a place for the temp sending unit. And tell us what the difference in readings are. I'm curious to know what the difference would be, if any.
