| ... very long under load. The 5.3 is OK , but just OK. The 6.2 is a beast but long term reliability is reportedly not great. I personally invested in a Sierra with the 3L duramax because I think it will be reliable (and I’m willing to absolutely keep up with maintenance). Just over 40k without any problems (knock wood). But there are not enough high mile trucks yet to really know. The 3/4 tons are ok. The Cummins Rams are better. | |||||

| Interesting cross-shop. 1) Regarding the Canyon/Colorado: The V6 gas motor is a decent engine. Average to above average reliability. But the 8-speed transmission it comes with is a potential problem, including in the Colorado (with an ongoing class action suit). The baby duramax comes with the 6-speed (which is fine) and is an all around better choice... if you can find one (they didn't make many). 2) The Maverick is a hot mess. The least expensive option on your list, but unless you have reason to get something that small I would stay away. 3) The Rid ... | |||||

| ... through all the gears 3 times: hard acceleration, medium, and gentle. See if there are any rough shifts. If it is shifting smooth, you’re probably ok. But don’t tow with it and change the fluid frequently as Scotty says. I also agree with getting an OBD chip to suspend the cylinder deactivation (check the search bar above; there are previous discussions here about that.) (FYI: the baby duramax uses the 6-speed, which is a good transmission. But they didn’t make many of those.) Welcome new member! | |||||

| ... get an OBS plug in that turns off the whole system. Overall, I think the best GM engine is the 3L duramax, but IMO the 5.3 is better than the 2.7 (turbo 4!) or 6.2... and probably better than any other half-ton engines on the market other than the Ram 5.7 hemi and maybe the Toyota turbo 6. The 10 speed is a good transmission. The 8 speed has had a lot of problems, but the 10 is significantly better. Any GM transmission can need a rebuild around 80-100k miles if you tow a lot. But if you don’t, I wouldn’t worry about it. (FWIW, I have the 10L transmissio ... | |||||

The 6.6 duramax is not great, but OK if you service it religiously. 4) Ford seems to have lost its way since the old 7.2 Powerstroke. I’d stay away unless your local dealer happens to be unusually ethical and organized. | |||||

| Should I change my ATF | 11Relevance | 3 years ago | Joshmplace | Submit Your Question HERE | |
| Scotty, I purchased a 2023 GMC Sierra 1500 3.0 duramax this year. 15,000 miles. The manual only specifies transmission fluid change for “severe” conditions every 45,000 miles. The dealerships want to “flush” the transmission which scares me. Do you recommend dropping the pan (and cleaning the pan and magnet) and changing the filter as oppose to the flush? And if so how often (mile interval) should I change the fluid and filter? I’ve seen in your videos you recommend not flushing but I just want to be crystal clear and positive. Need this vehicle to last a fe ... | |||||

| ... Colorado/Canyon a look. They're made in the USA and fit and finish is a step up from the previous gen (the 8-speed transmission is the question mark) Scotty just made a video comment about how GMC quality seems better than Chevy, and that new GMC trucks are OK. I don't know if that's just anecdotal. but FWIW, I have a Sierra with the 3.0 duramax and like it so far, going on 30,000 miles. Make a low ball offer on a Ram. They're made of feces, but the dealers are desperate. If you can get the price down low enough, you can keep the rest $ in a slush fund ... | |||||

| I totally agree with you about the mileage. I am flexible about the year, so most I’m looking at are higher in mileage. The reason I’ve ruled out the Ram 2500, isn’t because of the excellent Cummins engine, but their weaker transmission when compared to the Chevy’s Allison transmission. The Allison is best by far, and the duramax is close enough to the Cummins in quality and reliability. Also Scotty’s recent video shows how much more above average long term maintenance costs the Ram has. | |||||

| The 2014-21 V8 Tundra is very reliable, and can tow 8000 pounds alright. Much more than that and I would agree with @kp about a Cummins Ram 2500. As far as the “best, safest” towing experience, then actually the 6.6 duramax Chevy would be best. It will be a little more stable on the highway than the Tundra, and most people think it has better throttle response than the Ram. It just may not have the lifespan of the Toyota or Cummins Ram.

| Answer to: Should I buy a diesel truck for towing | 11Relevance | 3 years ago | Dad2LM2 | Submit Your Question HERE | |
| Under 10,000 pounds, an HD diesel truck is not necessary. The light duty diesels are a better option (especially the 3.0L duramax, which is what I personally drive), but most people go with gas. You don't mention budget, but basically I would go with the most reliable truck you can afford. Maybe start with a 2014-2021 Tundra to get the business off the ground, then upgrade when the loads demand it. | |||||

| If 21 is an option for you, then Tundra is the clear choice. The GM v8’s are ok, but have had lifter issues. The 3L duramax (which is what I have personally) is quite good. | |||||

| Use is critical here. For true heavy duty use, the 2500 will hold up better, for sure. For light-medium duty use, it's probably a wash (the 6L duramax is a good engine, but the cost of maintenance, fuel, and repairs more than offsets the benefit). | |||||
