I have a 2005 chevy silverado 2500 hd 6.0 the trans runs real hot. i changed the fluid and the filter. it seems that when i disconnect the cooler line no fluid is flowing through i took an air hose and blew air through it, it runs cool for about 1 hr. . then i have to repeat this process is there a transmission fluid pump that can go bad??

SOURCE: how do I replace the transmission coolant lines

Take a small 90 degree pick. Inspect the fitting closely. Use the pick to "roll" the retaining clip off the fitting. The line will simply pull once this is done. U can install the clip first on reinstallation (inspect them closely) and then simply push the line into the fitting. It will "click" into place. Note u will have to orient the line perfectly to push in.

there is a petcock at the bottom of the rad drain ti from there and use a antifreeze tester to check protection temp

CHECK TO SEE IF THERE IS AN OVERDRIVE SWITCH LOCATED IN THE SHIFTER! USUALLY YOU CAN PUSH THIS SWITCH TO DISENGAGE THE OVERDRIVE, OR RE-ENGAGE IT!
