  1. 🛞 Wheels & Tires
    I have a 2023 Chevy Silverado RST, second set of tires. 275/60R-20 Open Range AT Plus. Rotate every 5K. First set had sudden abnormal wear on inside of front tires. Aligned, replaced with new tires (wanted more agressive winter tires anyway), rechecked alignment, now abut 2,900 miles and...
  2. Manual Transmission
    Have a 5 speed standard transmission in my 1982 sierra. I was told that the tranny was out of a third gen camaro so I assume it's a GM T5 but it looks different to every one I've ever seen. ID marks aren't legible anymore so I'm at a bit of a loss. I searched thru hundreds of forums and pictures...
  3. 4-Speed Automatic Transmission
    I’m working on a 2007 Silverado 1500 (NBS) 4.3l 4l60e. Replaced the transmission but now the truck won’t start. PRNDL is saying that the truck is in 1st gear and when I hook my scanner up the tcm is saying that the transmission is in 3rd gear. I have checked all grounds and searched the harness...
  4. 4-Speed Automatic Transmission
    Hey gentleman! So I purchased a used 4l60e tranny for my 97 gmc c1500 along with a brand new torque converter. Installed everything only to find that there is no 2nd gear! UGGHH!! All other gears work beautifully! Any ideas fellas? Thank y’all! 😘
  5. ⚡ Electrical
    I've already found that my TCM is pulling about 0.35 amps and killing my battery. Problem is... I can't find the dang thing to change it out. Everything I can find in my Google searching shows that it should be mounted directly behind the ECM - I assure you it is not there. Where the hell is...
  6. Vortec 6200 6.2L V8
    I just wanted to ask if a L9H Vortec would fit my 2010 GM Sierra 1500, and what other parts/components I may need to get it to work properly. If there are any other long lasting engines that you know of that might fit better, please tell me. I currently have 281k miles on my 2010 GM Sierra 1500...
  7. 6-Speed Automatic Transmission
    Hi guys. I recently bought a 2012 GMC Sierra with 168K miles. It has a 6L80 transmission. Sometimes when I come to a stop, or am crawling in traffic or in a parking lot, the truck will shudder into first gear as it’s downshifting. I checked the fluid and it’s clean and at the right level and...
  8. 6-Speed Automatic Transmission
    I want to get the trans rebuilt on my 2013 2500 6.0 in the near future but I have no idea who or what brands I should look at/consider to rebuild with.. I want something maybe a step above factory performance but nothing overly crazy. The truck is driven as my daily at the moment but will at...
  9. 4-Speed Automatic Transmission
    After picking up dinner last night it put the truck into reverse to back out of my parking spot. The shift felt a little weird, but the engine idled down like usual when shifting to a gear from park. But when I let off the brake, the truck didn't begin to roll backward as it should have. I gave...
  10. 6-Speed Automatic Transmission
    2012 Silverado 1500 with 5.3 and 6L80e 260k miles Almost always let my engine warm up at least halfway before driving. Use 2wd almost exclusively, 4-hi maybe once a week during for very short distances. Last night I noticed that my RPMs seemed to be a bit jumpy, hardly noticible on the...
  11. Vortec 5300 5.3L V8
    2005 Silverado 1500 LS V8 5.3L RWD Here's the skinny: 1. Bought as a project truck with pink milkshake in the transmission and surge tank. Transmission only worked in drive and just barely. 2. Flushed the cooling system. 3. "Flushed" the transmission by detaching the transmission coolant lines...
  12. Vortec 4800 4.8L V8
    Hey Everyone, I’m new here but I appreciate the content posted by everyone. I have been browsing around and haven’t been able to find a problem similar to mine so I wanted to pick a few brilliant minds from the web. I have a 2008 GMC Sierra 4.8L 4WD with 330,000 kms and the transmission was...
  13. ⚙️ Transmission - Transfer Case - Driveline
    I've had this truck for a few months now. It's has 54,000 miles on it but it's been a lot of trouble.. Here's the latest issue... Now that it's getting colder, when I go to shift it from park into drive it clunks into gear pretty hard & I feel the truck sort of lurch.. it only happens on a cold...
  14. ⚙️ Transmission - Transfer Case - Driveline
    I need some help. I’m new to this forum thing but I need some questions answered. I have an 06 chevy silverado 1500 4wd with 112k miles, and it has already been through 3 transmissions. I bought it from a family member 6 months ago and it had a freshly rebuilt transmission with less than 1500...
  15. 4-Speed Automatic Transmission
    Hey all! I have an Automatic 2017 Silverado Z71 1500 4.3L V6 with Flex fuel. Months after my powertrain warranty ended I noticed my truck would occasionally clunk when shifting from 2nd into 1st. This became more frequent when I had it looked at, I was told it was a common malfunction with the...
  16. Duramax 3.0L I6 Diesel
    So I have owned this 2022 Silverado RST 3.0 Duramax NON LTD since May of 2022. Have had many issues with the truck, many haven't been resolved or just haven't returned. Started off with steering wheel controls for radio and volume not working followed by the blower motor not responding when...
  17. 6-Speed Automatic Transmission
    The transmission dipstick tube broke loose on my 2013 Silverado 2500. From what I hear it's a pretty common issue with these trucks.. I'll be able to get around to fixing it next week. How big of a deal is this? Will it cause any harm or damage my transmission at all or no??
  18. 6-Speed Automatic Transmission
    I'm going to need to have the torque converter on my 2013 Silverado 2500 6.0 replaced & would like to have a price range in mind of what it should cost all said & done when I go to the shop so I don't get ripped off. I know rates & such vary depending on location (I'm in NJ) but I'm just looking...
  19. 6-Speed Automatic Transmission
    Can anyone help determine the difference with AC Delco transmission fluid types. There are Dexron 6 10-9293, 10-9295, 10-9244 that I’ve found so far. What is the difference?
  20. ⚙️ Transmission - Transfer Case - Driveline
    This is on 2013 Chevy Silverado 5.3. So when I was driving the rpms started fluctuating and causing truck to shake some at all speeds it seemed. Got home started truck later and could hear a grinding noise while in park (kind of sounds like it's by transfer case). When truck first started it...
