well tomorrow will be 1 week with my new/used truck. it has 60k on it and i have some questions.

 

i never rode in a 5 or 6 sp truck so it has me worried a little.

 

the shifting in auto is hit and miss. 1st to 2nd seams firm sometimes and 2nd and up soft. but other times 2nd to 3rd is firm. is this normal? this is noticed when being easy/ rolling into the gas. hammer down its fine

 

when im crusing behind a slow person around 35 to 40 mph and doing small rolling hills. when ya let off and coast then get into the gas again, it seams like it doesnt know which gear it should be in and stumbles to find that perfect gear. is that normal?

 

when ya come to a stop, and ya roll it a little and go, the same thing happens, it doesnt know what gear to be in to take off again.

 

1 more, lol. from the forum i was told i got a 6L90-E transmission. if this is a 6 speed tranny, why is it if i use manual shift mode i only have 5 forward gears?

 

any thoughts or input would be awsome

 

thank

Check with the dealership and see if the programming has been applied to the TCM for the upshift/downship issues your having. Thats been a BIG complaint with early 6-speeds. As far as the 6-speed, are you counting overdrive too?

      Did you ever get this worked out? Mike is doing the two start thing now too. This is after a new camera back in December.

      AFM Disabler Question

      By KARNUT · Posted

      I’m doing an experiment on a vehicle I don’t have much money in. I’m going by the premise that after they last 100K miles they were no mechanical problems with assembly. Or defects with the parts. With oil changes by the minder for the first 127K miles when I acquired it. I quickly went through low mileage oil changes then settled on 5k oil changes with close to 170K miles on the vehicle currently. I did have the option to turn off the cylinder deactivation. I didn’t on this vehicle because it’s in ECONOMY mode at least half the time. It should be a no brainer frequent oil changes are the key. The manufacturer gets away with the long oil changes with its severe service  maintenance. Just ask them what is normal.

      Hot air constantly blowing through floor vents, drivers side only?

      By baglie1 · Posted

      Even set to "recirculated", the air pushes out and is hot. I have noticed that sometime it doesn't want to switch between recirculated/vented air. Say it is set to Circulated Air and I want to switch to Vented, when I click the Vented button, it just quickly lights up/clicks and immediatly switches back to Circulated. It's done this a few times now. So maybe it is an actuator getting stuck? But then, that doesn't explain the hot air when everything is off does it?

      Gas Prices

      I wonder what the price is out at the coast, Big Sur or other out of the way locations as I bet they are charging quite a premium over the in land pumps.

      2 speed transfer case optional now?

      By Chuck FB · Posted

      Were you looking at the HD trucks on the GM website or the half tons as that makes all the difference. As far as I know there are only two options for the HD trucks and that is the standard 2 speed transfer case or the 2 speed transfer case that has the added 4 high auto feature and they put that transfer case by default into the LTZ and High Country although its optional in the LT and not sure if its available in the work trucks.    The half tons, that is where its been a total mess in my estimation for a few years now with most trucks below the top trim having the single speed transfer case as standard but with the option of having the two speed such as one would get by choosing the Z71 package, however then not being able to get the two speed transfer case with the towing package unless it was a higher trim truck AND had the 6.2 gas so one could combine the towing package gearing diffs with the two speed transfer case. Having said that if its a trail boss package then it gets the two speed transfer case but not necessarily able to get the tow package as it would depend on trim level and engine chosen. Believe me, people have bought the GM half tons assuming "of course it will have a two speed transfer case" only to find out after when they really pay attention to what they now own .... crap, there is NO low range !.    I don't believe Ford or Ram have gone that way yet with their half tons but like I say its been a few years now that GM has done this with the half tons.
