Trans overheat light.....sorta.....
So this morning on my way to work I was on the highway moving with traffic at 70MPH. I heard a ding and looked down and my trans temp light was on.
History: with about 50K on my jeep after purchasing new I got the dreaded trans temp light, loud whine, and degraded performance. I went to the dealer and got the usual routine. "We didn't find any active or stored codes in the computer. There is nothing wrong with your Patriot". I had them do a transmission service with new fluid and filters anyway. After much discussion on this forum it was noted that the service intervals simply do not work. So I thought I would play it safe and change the fluid and filters myself every 50K. I changed them at 100K, and again at 150K. I am now at 193K miles. not far from another self imposed fluid/ filter change interval.
Differences: This time, there was no loud whine and no degraded performance. The light came on and I heard the chime. I kept going for a mile or so until I saw a good spot to pull over. When I did, I put the trans in neutral and sat there. The light went out in about 3 minutes. I sat there for another 5 minutes or so just to let the pump circulate the fluid and then back in gear and back on the road. No issues the rest of the way. I never got any abnormal noise or any degraded performance. The Patriot kept trucking right along at 65MPH until I pulled over.
I am getting ready to change the fluid again, but I am a little concerned that this did not seem to follow the "normal" pattern of what happens when that light comes on. Since the last change I have done quite a bit more towing. Nothing over the limits, just my zero turn on a 6x8 utility trailer to mow another piece of property I bought and hauling trash and lumber for projects. The most I have towed would be between 1200-1400 lbs. In my mind that makes me think the fluid has degraded faster this time and would explain the light. I'm not too worried that I can change the fluid and filters and it will be fine. Just a little concerned that there my be something else entirely going on since I never got the loud wine or degraded performance.
