Trans slip when pulling toy hauler
Hi, I have Chevy 2004 3500 6.6L V-8 diesel /Allison Trans 4x4 w/ 46000 miles. When I pull my toy hauler 11000 lbs. When the trans temp. hits around 200 degrees, I start to here a loud vacuum noise and trans start to slip as I try to go faster. Stays on for 3 to 8 minutes and will go back to normal w/ full power no slipping. Then about 5 to10 minutes later its starts again. Speed does not matter For 200 miles on and off. ''When I’m not pulling Truck trans. does not slip.
