hello,

 

not sure if this is the right forum or not? i have a 2008 yukon denali Xl 6.2 AWD so please let me know if i need to move this topic elsewhere and let me know where to find the appropriate forum.

 

yesterday i felt some resistance  in the column shifter and it happened suddenly. i only seem to feel the resistance from P to D only going past R and form D to P that same thing. when trying to get past R from D i have to pull really hard on the shifter towards me and it slips into P but with great persistence. seems really dry if you know what i mean?  has anyone experience the same thing? if so can anyone tell me where to start looking to fix the problem or what might potentially cause this Resistance? 

 

is it possible a bearing or some kind of bushing in the column needs some grease? or perhaps it is something to do with the linkage to the trans/transfer case? 

 

 

thank you in advance

You need a shift cable from the column to the transmission.

You should replace it before it breaks and your stuck crawling under the truck manually shifting it!

Hope this helps

Well I wouldn’t be laying in the snow trying to mess with it, after install it requires adjustment sometimes and you’d have to be laying down while someone moves the lever and checks for proper engagement and I’m not about that life so I’d take that one to a shop.

Hi,

 

i crawled underneath the truck and looks like the cable seems to be functioning as it should, i took the cover of the column and inspected the column shifter. it appears to me that the "yellow" spring ( please see pic) has collapsed/broke as the shifter kinda dangles when you pull on it. is this spring replaceable? i am pretty sure this is the culprit as this spring compresses the most when shifting in and out of R

 

PS this is not my vehicle in pic - its from a you tube video lol

 

thanks

Wow those always break on 99-06 trucks haven’t seen them on 07+.

Anyways you can technically replace that spring but it’s a pain and there’s a chance of stretching the shift interlock cable. I always replace the shift control assembly.

Good find! Never seen the newer ones broken it’s always the shift cable.

well from what i can tell it is the spring. when the shift lever is in P and i pull on the lever to put it into a gear it is very sloppy/loose. Most noticeable when in P as it kind of just flings forward and back with a light touch with a finger. it dosn't seem to be binding now when i try to put it in R from P or R from N however the sloppiness started soon after the binding went away.

 

anything else i can look for? the spring doesn't seem broken but i cant tell for sure. do you have a pic of a shift control assembly just so i can confirm what we are exactly talking about? seems like the scrap yards only sell the columns as a whole unit only. 

 

can i change this control assembly with out removing the whole column? if so maybe i can just order a new part Vs replacing the whole column

 

thanks

      The Peckish Synapse

      By Grumpy Bear · Posted

      You're better read than that Atlas. 😏   British science fiction writer Arthur C. Clarke formulated three adages that are known as Clarke's three laws, of which the third law – that "any sufficiently advanced technology is indistinguishable from magic" – is the best known and most widely cited.   Stribeck and the pivotable Hersey Number isn't voodoo nor snake oil. That part is physics. It's what marketing and bean counters do with it that is snake oil and voodoo.    Stribeck is the relationship between Hersey and the Coefficient of Friction. Within the Hersey Equation if viscosity and viscosity is 'Dependent' on.......heat.......and.......viscosity index or the temperature to viscosity slope.    Specifically Hersey is the viscosity AT THE TEMPERATURE IN THAT LOCATION FOR THAT SLOPE.   Hydrodynamic lubrication exist when the film thickness in the location is 3X the Ra roughness of the surface. This is irrespective of the hardness of the substrate. To obtain that thickness X viscosity is required for Y velocity at Z load. That's a lot of moving parts. It is also impossible to maintain in an ICE but nearly possible with a turbine under constant load.    What does that mean? Error heavy and operate light. Wear is inevitable but the rate of wear and the milage obtainable are a function of prevailing conditions and HABITS. The only penalty is viscous drag and at fractions so low as to be well worth the effort. Double the life, half the manufacturing carbon foot print. Greed is the only impediment.    The materials generated by SwRI are the RESULT not an estimation or a hypothesis.    Don't delude yourself sir, EV's have as many pitfalls as ICE's. We just don't know what they are yet and it will take longer to sort as MARKETING and GREEDY CEO's have had more time to polish the turd they are selling.

      You can always count on greed to prey on ignorance and stupidity.    Friend bought a 2019 Ford Flex and asked me about using Valvoline R&P 5W30 in it. Told him give the miles on it and the fact it wasn't yet using oil that it was a good plan. He uses a Valvoline quick change shop for his oil service.   First they tell him that isn't the oil the OEM recommends. He told them he didn't care what the OEM thought. Then they floated the, "But it will void your warranty"    His reply was it's a 2019, there is no warranty and informed them their knowledge of the law was lacking.    Then they tell him 'But it will ruin your motor"!.    Mine to ruin he says. Finally they give in and charge him 150% the semi-syn price    Point it the brainwash is so embedded that even the service industry is drunk on their swill. The public is right behind them. Echoing the same lies on every forum and media platform. If the end goal is indeed EV then I'd say that ship is about built.
