Calling all Chevy Colorado owners....

I agree its maintancethats a major factor in an auto tranny. I know when I had my tranny fluid and filter changed. I also had the bands adjusted. the truck shifted like a brand new truck. my gas mileage went way up. from 120 miles on a quarter tank to 165 miles on a quart tank. I think gm makes some of the best trannys around. my dad had an olds vista crusier with over 300,000 miles and I doubt he ever changed the tranny fluid. a tranny fluid cooler is a great thing to have on one. I am going to get one soon for mine.


I saw on MSN website that the colorado and canyon are the worst reliable truck on the market. as I odnt read to mcuh in to this. as they have the honda ridgeline as the most reliable truck. and the ridgeline has barely been out a year.

I have heard caddy was talking about bringing back its V-12.
 
Well, for 06, GM upgraded to Dexron-VI, so fluid durability problems should be history.

If one dropped the pan, changed the filter, refilled, flushed an additional 2 gallons through the cooler lines, every 50,000 miles (Severe Service Schedule), they shouldn't have any "fluid-related" problems, theoretically.
 
Hi

My 4T60-E has the 220,000 on it, my last car, another Olds is presently a local cab and still has its original tranny at over 300,000.

The Olds before that had over 270,000 when I traded it...so it is reasonable to assume that they can be rather fine pieces of machinery.

I change filters every year, and drop the pan several times again over the filter change, so the fluid is always quite fresh. A B&M trans cooler was installed when I first got the car.

Same here, I take in those critics about as well as I read movie critics.

According to them, I've already had my share of owning 2 "unreliable" vehicles in the last 15yrs, funny thing is, is they've been/were more reliable then the vehicles listed reliable.

Personally, I believe it's all in the name.

Many of those reviews have always stated that the Isuzu Rodeo was an "unreliable" vehicle, but the Honda Passport was "reliable" - funny, I always thought the Honda Passport WAS an Isuzu Rodeo??

I agree, I don't see how they could have acquired any kind of reliability factor on the Ridgeline OR the Canyon/Colorado - neither have been out long.
 
Ramblin, I spoke with a cpl GM techs prior to buying our '05 trailblazer, they claimed to have seen VERY few issues with the 4/5/6cyl versions of this engine, granted it's only been around since ~2002. You will like the 4L60E over the 4L30E. It's got a dipstick, it's all in one case/housing, unlike the 4L30E with the 'adapter' case & seperate pan for OD/4th, plus parts, knowledge and aftermarket are plentiful, unlike the rare and discontinued 4L30E. Personally, I love manual trans, just not in a DD truck. It's more of a chore than fun in a truck IMO.

G/luck
Joel

Not too odd, but kind of crazy:

What kind of truck did GMC offer a V12 in?

I always thought the only V12 GM ever made came in a Cadillac back in the 30s.

From Wikipedia:

"Finally, there was a 702 in³ (11.5 L) "Twin Six" V12, which was basically two 351s placed end-to-end and was used in full-sized commercial trucks."

I thought that it was interesting that they describe this engine as part of the V-6 history. The 351 was a V-6. This engine was apparently available in the '60s.
 
I'll make sure all tell the guys at GM you like them! The Canyon and Colorado are made here in Shreveport along w/ the H3. Lot's of 'em here. Some bigwig lives a few streets over. He's been driving an H3 since it was in the early pre-production stages.

If I needed a truck I'd get one...or that spotless BRAT I saw on a used lot today!

Interesting. My uncle had a GMC pickup in the 60s with one of the V6s in it.
 
The inline 5 is a packaging deal. I think it's kind of neat but wonder what compromises were made balancing it, or making its vibration tolerable.

It could be stout, back in the late 1930's chevy was really into its inline 6 when ford had its flathead V8 and they argued back and forth about their plusses and minuses. But the single long crankshaft will have more bearing support and there's only one head gasket, valve cover gasket, etc.
 
I don't know how correct this is, but I've heard over and over that GM didn't make the engine bay in the Colorado/Canyon big enough to support the I6 from the Trailblazer/Envoy. I think this was a mistake but I still don't slam the I5. It's a great engine IMO.

I believe that in 2007, the 3.5L I5 will increase displacement to 3.7L. It will be interesting to see what kind of power increase they give it. I'd also like to see an option for the 4.8L V8 in the trucks. I think the 5.3L V8 would be too much engine. The 4.8L V8 would be the right size V8 for those trucks IMO.

Are you saying the Inline 5 only has one head gasket and one valve cover gasket?

COOL!
