    Hey all, I've got a 2003 LB7 Duramax with 240,000 miles and a Bully Dog tuner throwing p0700 and u2106. I know the p0700 is a MIL request from the TCM and the u2106 is lost communication with the TCM but I don't want to sink money into a new TCM if there's a cheaper fix. The truck shifts hard...

    I have a 2007 duramax, and it’s giving me transmission issues. This all started after my internal trailer brake system went bad, and I installed an aftermarket to bypass the module. I was pulling a heavy dump trailer and the trailer got hung up and I had my wife trying to tug me out. After about...

    I have a burnt up 2006 allison 1000 out of my 2007 lbz 1 ton dually. I purchased another Trans out an 07 lbz but it doesn't have input speed sensor on bell housing like mine does.

    I’ve been looking for a good core to rebuild to just swap into my truck and this guy a couple hours away from me claims he has an Allison 1000 6 speed from an 06 classic with only 130000 km on it. I’m not to good with identifying serial numbers or dates but here’s the picture of the tag. Any...

    So I recently cracked the bell housing to my transmission and it lost all the oil. I’ve been looking around at good used transmissions (used because it is my work truck) and I’ve been told the plugs and other things change from year to year. I have an 06 LBZ with the Allison 1000 six speed. Am I...

    A 2004 lb7 GMC 2500 crew cab short box has just come into my possession, before I got it the front differential didn't disengage and blew the u-joint in between the front driveshaft and the t-case. That sent the driveshaft flying around and it smashed the trans at 120 kph breaking the shift...
