I just installed an auto trans temp guage and am wondering what would be a normal operating temp, loaded or towing temp and danger zone temp......<br><br><br>Thanks,<br>Rich

 

Rich:<br><br>The base temp is according to where you have the sender installed. In the outline or cooler line you should see 130 normal, 160-180 towing; get concerned over 220. From your sig you still have a stock tranny. My stock ran 20 or more deg more than aftermarket. Heavy towing I would see 180-200. Now 150-170. 170 is the max I have seen towing 26K in hill of WVA (I-77) lots of steep hills.<br><br>A recent issue of tdr had a scale that began at 175 deg. If you run over that the life of your tranny starts going down hill, and rapidly with any increase in temps. I have seen where the &quot;ideal temp&quot; is 140-160. But mine never runs that high, normally. Hope this helps<br><br>george

 

I have my guage in the cooler line coming out of the tranny,<br>pulling 15k in traffic will rise to 185 to 190.<br>As soon as i get rollling down the highway it will drop to 125 and stay there going up and down hills.<br>If i have to shift down for a slow down or get off the highway it will rise to about 150 until i hit traffic.<br>I have never seen 200 so far and i hope i dont.<br>I have 3 coolers on mine.<br>The stock one on the side of the block,<br>The one up front of the radiator,<br>And the one under the lft side of the bed.<br>Plenty to kep my tranny nice and cool.<br>It seems to like that or at least so far.<br>I change my tranny fluid every 5000 miles and change the filter every 10,000 miles.<br>This might be over kill but alot cheaper than a tranny.
