Stop Leak - Ugh!
First off, I again want to Thank the Forum for again helping to solve issues on my Coach.
I especially want to Thank Scott ( DSD ) and Greg ( Mister Ed ) for their assistance and knowledge. Scott and I spoke and his troubleshooting is what solved my problem and Greg's previous post about his transmission cooler guided me to my fix.
My issue was that all of a sudden, my trans temp was running about 20 higher than the coolant temp, and my coolant temp was higher than normal. What I thought was a fan issue ( I posted asking about my fan controller ) turned out to be a trans cooler issue.
The issue............Trans cooler was totally clogged with Stop Leak. I had a very minor leak that I noticed last year. I added the Stop Leak and tightened the side gasket bolts on the radiator and the leak stopped. Great ! or so I thought. My next trip is when the higher temp issue started. What I thought was the fan, Scott said to check my Trans Cooler for clogs.
Sure enough, after draining, 15 gallons of radiator fluid and 5 gallons of trans fluid, getting all the fittings and connections loose, wrestling the cooler out and WOW, totally clogging with a very thick layer ( about 3/8" thick ) of what I would describe as thick felt like material.
See the pics below, I wish I had taken a shot of the clogged cooler, but I didn't think about it until it was clean. That material is literally like a felt cloth. Got it all cleaned up, I will be flushing the system tomorrow, a then servicing the trans filters, putting in all new fluids, then the road test.
I am 100% positive that this was the heating issue. Thanks again to all for their knowledge and help! Scott, hope that knee is healing well.
Beware of the Stop Leak !
