Hello I am new to duramax’s and this forum so look forward to learning here. I just bought a 2004 Chevrolet Duramax, 94k miles and the transmission seems to take a very long time from the 2-3 shift. It’s kinda like it’s slipping but not really. I checked the fluid which is at the proper level and really don’t know what the problem is. Any help would be greatly appreciated. I have a video but this forum won’t let me post it?
