Consumer Description

My Tahoe has the New Process 246GM transfer case. They have a known issue called pump rub where the pump is to close to the magnesium shell, and rubs pin holes in the shell which causes fluid to dissipate over time causing the transfer case to run dry burning it up. I've had a mechanic check it out and there was no fluid in the case, and now I have a transfer case that's burned up. I've called a transmission shop, and they told me it was a common issue. I would like for general motors to correct this issue
