2017 Trans ?

[MR. DRAG SLEDDER]

Ok my lease is up in Dec. and started looking for a new Truck

 

- Trans. do some 5.3's have a 6spd and others with 8spd.

[powerhaulic]

yes

 

High line LTZ / STL and above get 8spd

LT / SLE get 6spd

 

I love my SLT 6.2 8spd NHT max tow

NHT is the only way to get 3.42 gear instead of 3.24 with 6.2

^3.23 he means.

 

And the LTZ/SLT comes with a 8-spd, 3.42 as well.

LOL yup 3.23

3.42 with 5.3 yes

Can't get the 8 sp in a extended cab with the 5.3.

[MR. DRAG SLEDDER]

My dealer has both? One SLT with a 6spd. and one with an 8spd....

Sure can, just needs to be SLT, LTZ or above trim level

Personally I wouldn't even think of buying another sierra/silverado until GM proves that the 8-speed isn't a complete piece of shifting & clunking garbage like the current one. It the one thing that honestly has given me buyer's remorse with this truck. I feel like I was swindled.

Yes this is correct. Must have one of GAT, PDT, NHT or L86 for the SLT crew to get the 8 speed.

On DC it must have the L86 (6.2) to get he 8 speed.

 

M5U Transmission, 8-speed automatic, electronically controlled with overdrive and tow/haul mode. Includes Cruise Grade Braking and Powertrain Grade Braking

On SLT - Included and only available on Double Cab models with (L86) 6.2L EcoTec3 V8 engine. Included and only available on Crew Cab models with (GAT) All Terrain Package, (PDT) SLT Crew Cab Premium Plus Package, (NHT) Max Trailering Package or (L86) 6.2L EcoTec3 V8 engine.

8-speed is available in the SLT, but not standard. Mine is a 6-speed.

You thank the EPA and CAFE standards for that.

 

Get a tune. It'll be the best $400-500 you've spent. Had one on my 1500 and it was a whole new truck.

Is it true tune =no drive train warranty? I can't get dealer to fix my trans without one.

I am right there with you. My first to second gear feels like i'm getting rear ended everytime I drive it. I absolutely hate it. Stealership told me it's a "normal... well normal issue", but refused to do anything. I'm waiting for the class action. I bought this truck with plans to lift it and now I'm afraid to do anything as when the transmission finally blows, i'm sure they'll blame it on the lift.
