  1. I have a 2001 2500 HD with ZF6 6 speed manual transmission 4*4, I bought the truck at a deal and am finding out why......it's a unicorn...lol. I am just a blue collar worker like most of the rest of us and can't afford the $3500 price tag on a rebuilt trans especially since I don't have a $1000 core transmission to trade them. I still have the transfer case and driveshafts and all other parts to the 4*4 trans..I found a 2wd ZF6 6 speed trans with only 140,*** miles on it I can get at a steal and am wondering if I can change tail shaft and make the 2wd into a 4*4 transmission? Any help would be greatly appreciated even possibly part #'s if possible.....I guess I can drive the truck as a 2wd if I have to but 4wd is one reason I bought the truck....BTW this is my first diesel so any and all help is appreciated..... ONE I WILLIE
  2. Hey everyone I am a long time lurker, first time poster looking for some buying advice for my next GM truck. I currently own a 2015 Silverado CCSB LTZ 4x4 with a 5.3L/6speed/3.42 power train. I am looking to upgrade to a 2017 LTZ but I have a few reservations regarding the performance of the 8 speed transmission. Some background, this truck is the first vehicle I have ever owned that feels legitimately quick. I like the feeling of power and how quick it moves hammer down. I don't want to lose that. After reading some reviews I am not really sure what to expect going from a 6 speed to 8 speed. Here's a review of a 2016 Sierra All Terrain X 4x4 CCSV with a 5.3L and 8speed http://www.caranddriver.com/reviews/2016-gmc-sierra-1500-4x4-all-terrain-review Its performance is as follows (its very similar to my 2015 6speed) Zero to 60 mph: 6.6 sec Rolling start, 5-60 mph: 7.1 sec Top gear, 30-50 mph: 3.4 sec Top gear, 50-70 mph: 4.4 sec Standing ¼-mile: 15.1 sec @ 92 mph Here's a review from the same source for a 2016 Silverado LTZ CCSB 4x4 with a 5.3L and 8 speed http://www.caranddriver.com/reviews/2016-chevrolet-silverado-1500-z71-53l-8-speed-automatic-test-review Zero to 60 mph: 7.2 sec Rolling start, 5-60 mph: 7.7 sec Top gear, 30-50 mph: 3.9 sec Top gear, 50-70 mph: 4.9 sec Standing ¼-mile: 15.4 sec @ 90 mph Any idea why the Chevy is so much slower? The only powertrain difference I could find was the performance exhaust on the GMC. What kind of performance can I expect if I order a 17 LTZ 5.3L CCSB 4x4? Thanks in advance for your answers!
  3. Hi all, I am new to this forum and decided I would post about my issue since I can’t seem to find anyone with the same issue on a 6speed 2018, only 2017s and below... I have an extremely annoying fish bite/stutter when cruising up light inclines on the highway and while the stutter is happening, my RPMs are bouncing ever so slightly (probably about 50-100). It’s minimal bouncing but it almost replicates what would be a misfire or a transmission issue. Truck has 22000 kms on it. I have been dying to get a Diablew tune but I really want to see if I can get this issue fixed beforehand. I brought it to the dealer twice and they checked the TCM for updates and nothing. They checked for TSBs and nothing. They took it for test drives and “could not duplicate the issue”. I’m getting sick of my dealerships lacking desire to fix my issue. Has anyone had this issue and got it resolved? Would love to hear any feedback. Thanks.
