This is a brand new, OE-quality internal wire harness for the Allison LCT1000 (also fits LCT2000/2400) transmission found in GM trucks with Duramax diesel engines, specifically from 2006 and up (Generation 4). If you're having electrical issues with your transmission \u2013 shifting problems, solenoid codes, or no communication \u2013 a faulty internal harness is a common culprit. This harness replaces OEM numbers like 29543336, 99645, and D121446C. It's a direct fit, designed to meet original specifications. Installation requires dropping the transmission pan and valve body, so it's a job for a knowledgeable DIYer or a transmission shop. But replacing a bad harness is often much cheaper than bigger transmission work. Comes new in its packaging. A crucial part for keeping your heavy-duty truck's transmission shifting smoothly. Always diagnose the problem carefully before purchasing.
