Ording Guide

Found it over on GMI. This sucks big time!

 

It wasn't offered this past year either that I know of

sorry I thought you meant manual

 

It just says the 4 speed is standard. I wonder if the 6 speed will be a late option. I think it at least needs to be offered on the 6.0L trucks.

2500's come standard with a 6speed auto 6.0L combo.

I can't believe the 4.3L is still around. Its cheap and reliable, I guess that is what is important in a base work truck.

edit: I see under Suburbans RPO's it has a 6 speed auto

 

It's really not a big deal.

The 4 speeds are fine.

The only reason people expect a 6 speed is because they somehow, think it is better then the 4 speed.

With GM's bullet proof auto's.....what's the problem?

 

The current 4 speeds in the 1/2 ton trucks are not fine. There are not designed to handle the amount of power in the currect engines. Just look at the torque management required with the 4 speeds.

 

The 4sp is not fine - that gap between 1st and 2nd feels larger than ever - and it doesn't exactly have a sterling reputation for durability.

I've spent some time with Ford's 6sp auto recently, and the extra ratios are really nice. Of course, it's also reinforced my opinion that GM's calibration is still better than that of the competition's.

 

i drove an 07 denali, and the 6 speed in that truck was nice. GM needs it in ALL of their trucks, although it is nice to know they are putting it in their HD models. Also i couldnt find anything about the 6.0 in a suburban, surely they arent using the little 5.3 for 3/4 ton models are they?

 

When your competitors are launching huge ad campaigns about how they have it and you don't, and it has already been developed, and you have been expecting it to be included because people have told you that is the GMT-900 direction... It sucks to see it excluded for 2 years.

 

The 4l60e is nowhere near bulletproof in these new trucks. The only time I can spin the tires is when the road is wet... TQ management

 

I guess it is a good thing most are using the 4L70E.

 

Go say that at clubgp.com, and see what reaction you get.

The four speed hydramatics have been hampering GM vehicles' performance for some time. It's not the number of speeds per se, so much as their inability to stand up to the torque in today's engines. What's the point of building the best motors in the industry only to handcuff them with restrictive torque management to protect glass jawed trannies?

 

So what various models of 4-speed and 6-speed autos are used in the GM half ton trucks? 4l70e and what else? So you guys expect the 6-speed in the Denali and Cadillac trucks to be more durable?

 

The 6spd should be stronger seeing as it is not just another modified 700r4. It is a total new design from ground up.

 

I personally won't buy another 4 speed auto car ever again

The extra ratios are very nice to have whether you are at the track or on the way to the grocery store.

 

Does the 6 speed get better MPG. I cant beleive GM is not offering this tranny on the new trucks
