We have a CAT D8N ( 5TJ ) And just did a full machine rebuild 120 hours ago, Then transmission temp gauge is maxing out to 250F And the warning light is on. We shot the trans case with a infrared gun and it's sitting at 220F, The trans filter housing is at 193F. Oil is clean, no burnt smell, shifting fine engine cooling temp is ok, no trans filter bypass light. Any thoughts possible wiring or sender problem. We are about to pull the operators floor pan and shoot the trans sender, but the dirt is coming in to fast to stop it for any long period of time.
Thanks !
