Hi everyone, im having over heating issues with my 06 lbz. Under normal driving the trans temp will climb above 200 and continue to rise until i pull over and let it cool. It started one day in about 15 degree weather the trans got to around 290 before i noticed it. I shut the truck off and let it cool to drive it 10 miles home. The next day after checking fluid levels, it was full. I then changed both filters and fluid because of the fluid smelling burnt. It seemed to be doing better until the following day when it got around the 250 mark. Once again i drove it home after letting it cool and dropped the trans lines and blew air through them to make sure they were not clogged. Trans lines have been replaced and i don't have and leaks. I'm not sure if im looking at converter issues or what but i noticed after the overheating the converter sometimes seems to stay engaged at a lower rpm than it should cause the truck to shove through the breaks if your not careful. I'm lost from this point. Any help would be great. Oh btw truck has 230,000 on it and trans is stock as far as i know. Thanks in advance.
