Any particular reason we can’t get the l5p to have turbo whistle like the lml? I like the growl don’t get me wrong, but at low rpm I’d like more whistle.

Just got a 2010 LMM and had 120hp tune on and it went in to limp mode and I scanned it and it said p0700 transmission control system could it be a bad tcm? Or does that mean my transmission is damaged which would suck cause I just got it a day ago

So I was at the dealership getting an oil change and the service provider said my vehicle was due for its 45k mile service which includes draining and flushing the transmission lines/fluids. Some folks have told me they never had transmission issues until after they had their transmission flushed. I’m new to diesels, so my question is, at 49k miles on my truck, what are y’all’s thoughts on it? I really appreciate any feedback. Thanks!

Posted last month about the wiring harness for the pistons going bad in my 3.0. My truck is back in the shop for the same issue and now the fuel rail “harness” and some injectors need replaced. 5-10 days just to get parts.

I was backing into my parking spot and BOOM lower control arm broke and ball joint gone. I replaced the lower control arm along with the ball joint and lowered it and it kept the same kachow stance. I changed the shocks and still the same stance all the way on the ground. I’m lost I don’t see anything else broken I need help I don’t know what to do.

I picked up a 2007.5 LMM with a 6” lift and 35 Toyo MT. It came deleted egr and dpf and has a mini max tuner. I read that the higher the tune the more fuel efficient as long as you aren’t hard on the gas. I have it on the highest tune and spent the last fuel tank driving it around town making sure it didn’t go over 2k rpm in the city and got 12.5 mpg. I wonder how it compares to y’all.

I checked the sidebar and didn’t see anything against posting an item for sale, but mods feel free to take this down if it’s not allowed.
This is the factory camera that mounts to the back of a trailer and connects into the factory stereo screen.
It has never been used - package is open but I believe all parts are there.
If anyone is interested, PM me with an offer - I can send pics.

After doing my transmission fluid change and driving for about a day I noticed there was a leak at the gasket and saw that my pan was bent. I bought a new pan and gasket and I am wondering since I’m not changing filters again, how much fluid should I put in? I know the capacity is 7.4 quarts but what is it if the filters are still full, if it’s still 7.4 or a different amount. Thank you

I've got a 2012 chevy and I need to replace at least the middle daytime running light. I can find the bulbs all over but not the housing. Any recommendations? I just want factory lights.
