Transmission cooler June 07, 2016, 08:42:58 pm Yahoo Message Number: 15241Has anyone put a larger transmission cooler on their C5500? I have a 10 mile hill over here in Vantage Washington and when the temp outside is up in the 90's as it was last weekend my transmission will warm up and spit fluid out of the breather. I changed the fluid out about 2 years ago and don't think I over filled it as the fluid level checks out fine when hot or cold. any ideas would be helpful.thanksMark2006 Seneca 34SSPulling a Chevy Tracker 4 door.

You probably have to much oil in your transmission. Which puts oil into moving parts of the transmission. This causes it to foam.BestRon Hall Quote Selected
