1988 Gmc Silverado Workshop Manual
Here's a copy of the 2007-2009 GM/GMC factory service manual for trucks. It covers trouble shooting and advice on what and how to repair/rebuild everything with torque specs. 4.3L engine to 6.6L trucks with everything form bumper to bumper. When you click on the link it will ask for your dropbox info, just click the link on the bottom that says 'no thanks, continue to download' You have to wait for the file name to appear above the download tab too.
Its a large file be patient. Edited April 30, 2015 by 08 Sierra Denali Guy. Good morning guys, Obviously I'm new to the forums, so thank you in advance for your understanding! A little background on my situation - I always make sure to maintain my vehicle to the best of my ability (both proactively and within my financial budget), but my Chevy Silverado just hit it's 75,000 mile mark with no previous transmission fluid maintenance. 2011 Chevy Silverado 1500 (Standard Work Vehicle) Pre-Certified with 3,008 miles on it, pretty much brand-new - Purchased in Oct, 2013 4.3 Liters V6 Engine 75,600 miles currently The only thing it's ever towed is the smallest Uhaul for about 600/miles, and sod back in the day. For the past couple of years I've only driven it to and from work (50 miles round trip in city/highway), but for the most part this past year my new place of employment is super close, so that dwindled to around 25 miles round-trip. I've only ever replaced the engine oil and filter regularly, and tires a year ago, so when it comes to how I should maintenance the transmission oil, that's a bit foreign to me unfortunately.
I've heard if you make it passed 70k with no issues, it's not wise to flush it out entirely, but more so the 50/50 (old/new) method? I would like some advice from you tenured vets on this, and to see if I should take it to the Chevy dealer or a transmission specialist? Thanks again!
Good day, I have a 2012 GMC Sierra 1500 Z71 4x4 SLT. Latley I have had an issues with the shifting. Most of the time all is good, but when I'm going between 35 and 40 and let off the gas then give it some gas it hits real hard. It does the some what of the same when I am on the highway going about 70 and I give it more gas. On the highway it seems to down shift ( feels like I'm stopping) than shifts hard.
The transmission was just rebuilt and I just replaced the tps and cleaned the throttle body. I at a loss and am running out of money to throw at it. The transmission shop ensures me it is not the shift soleniods, he says if it was I would have a lot more shifting issues than I currently have. Also, the check engine light does not come on and there are no codes in the history. Any help would be appreciated. I'm very frustrated about how GM denied an extended warranty coverage case on a well known production issue of their 2008 GMC Acadia (and many other models, see list and bulletin). Up until now I was very happy with my car and even considered upgrading soon but the way GM handled and communicated my case is careless and completely unacceptable.
On Aug 6, while literally on the way to the airport for my family vacation to Europe, the check engine light came on and we had to take the airport shuttle instead. After returning in September I had the car towed to the dealer who diagnosed a faulty 35R transmission clutch wave plate. A quick internet search turned up service bulletin #14404 (describing this issue as a common and well known defect in many early models (including mine), as a matter of fact grave enough to extend the warranty to 10 years and 120,000 miles. I called GM customer engagment who bluntly denied the warranty because it had expired 2 weeks prior the diagnose.

This is upsetting because the mileage on my Acadia is way below 120,000, the problem originated long before the expiration date and there wasn't any communication that would have notified me of that issue or triggered a sense of urgency to bring in the car before going on vacation. I strongly believe that it is GM's responsibility to rectify this well known issue under the extended warranty conditions given the above described circumstances. I'm happy to provide further evidence (plane tickets, diagnosis report) and look forward to your reply and a resolution to my problem within the next 3 days.
