tammypcb Report post Posted Monday at 04:04 PM 2010 Entegra Anthem 42DL Allison 3000 transmission. I have owned for 4 years and transmission temps continue to fluctuate. With Ambient temps 80 pulling a toad trans temp at 60 MPH average 196-200 degrees. When I get in traffic temps jump to 210-213 degree's. It takes about 10-15 minutes at 60 MPh to cool back down to 200-202. Recently I drove it under the same conditions and the trans temp averaged 165-172. Same driving conditions. About 60 miles in the temps jumped to 202-210 with no change in ambient temps or driving conditions. I was surprised that the temps were so cool initially. Then the temps just jumped like a switch was thrown. Could this be a problem with Cooling fan? Transmission Flush? Share this post Link to post Share on other sites
