After many many hours of forum reading and trying to find a answer for a problem like mine I've finally given up and decided to just ask.
I've got a 2001 Silverado 1500 LS 2wd with the 5.3L. We were driving down a back road the other day and to simply say that it was muddy would be a huge understatement. Had I not know better I wouldn't have believed it was an actual road and not a trail. The mud was so deep that it reached clay in spots and we basically snowplowed mud with the front bumper. After making it back to the highway we went to go accelerate only to be bounced around wildly and were unable to go much faster than 80km/h due to a random and sudden lack of 3rd gear and overdrive. Limped the truck home and did a transmission fluid and filter change the next day. Fluid was filthier than heck, dark dark brown in color sort of like Cola. After that now the truck sometimes finds 3rd but 4th is nowhere to be found and once you get over about 70km/h it shakes so hard it feels like the worst washboard despite doing our best to get all the mud out of the wheels. Reverse still works fine. Looked under the truck and there does appear to be a bent crossmember but the frame still looks fine and straight.
Some backstory; Never had any transmission problems before this or signs of slipping. The tires on the truck are oversized, from a stock 245/75r16 to running 275/70r17. At present there are no rear brakes, had a bolt on the caliper come off one day and long story short ended up disconnecting them and pinching off the lines for the back brakes. We also have kids who like to play driving and occasionally jerk on the shifter, one day our toddler somehow manged to get the truck out of drive without hitting the brake and it started rolling, it didn't go very far before I stopped it but nevertheless was certainly surprising.
So my question is; what could be causing this to happen? Is the transmission completely gone and if so why no warning signs? Could it be the 3/4 clutch pack, the shift cable, transmission mounts or something else? Any input would be appreciated!
Hey everyone - first post here and just bought a new-to-me 2014 Silverado 1500 LTZ Z71 all stock. This is also my first truck so I'm definitely a newbie and if I'm asking some simple questions I apologize, but I couldn't find the answers I was looking for on other topics.
Basically, what I'd like to do is level my pickup. I thought about doing maybe a small lift but I don't really want to fork out the money and I think the leveled Chevy looks just fine. Any recommendations for this? Seen people put on 2 or 2 1/2" level kits - difference between my wheel well heights is pretty much exactly 2 inches.
The other thing that I'm having more difficulty making sense of is a wheel and tire combo. Currently, I've got P265/65/R18 on it. What I'd like to do is get a bit more rugged look while also getting more ground clearance for a bit of offroading, and hopefully not affecting fuel economy and ride quality too much, but I understand you gotta sacrifice somewhere. What I'm having trouble understanding is if I should get larger wheels or taller tires to achieve the ground clearance part. I've read that getting larger wheels can mess with your speedometer and such. Any advice on if I should stick with my 18's right now, and if I end up buying new wheels one day should I also stick with 18's then?
If I went ahead and got my pickup leveled, which (or both) would help me get that better ground clearance? Increasing tires or wheels? What's the largest combo you'd recommend (with the level) that still prevents rubbing? Definitely want to get that rugged look but I haven't been able to determine which route to chase down, as the options seem limitless out there for what you can do. Could I just get bigger, more rugged, maybe wider tires to put on my stock 18's?
Thanks in advance to anyone willing to give a newbie some advice.
Trying to find out if I can fit the stock wheels and tires from a 2020 GMC Sierra Denali 2500hd on my 2016 GMC Sierra 2500hd with stock suspension. I know the bolt pattern is the same and based on what I have seen on the forums the 275/60R20 tire will fit with stock 2016 wheels without rubbing but I'm concerned the slight difference in offset from 44mm on the 2016 wheels to the 47mm on the 2020 wheels will be an issue. Has anyone tried this yet?
