72k on the truck, and never flushed the trany. Took it in today, and they said the flush could make the hard-shifting that I am currently experiencing worse within a couple thousand miles. . . Thoughts, suggestions?

Pretty much true. if it's never been flushed in 72k, you can do a service change (drain & fill) but an actual flush will most likely lead to failure of the trans. A flush stirs up a lot of debris in the hydraulic passages.

Yep.. ONLY do a drain and fill.
Easy to do. Drain out fluid into a large (1 gal+) container. Replace drain plug. Measure amount of fluid drained out. Replace with same amount of new fluid into the tranny dipstick hole. Because there is a lot of fluid trapped in the torque converter and passages in the tranny, if you want to get almost all the old fluid out of there, drive the truck after the fluid change for 10-20 miles, then repeat the drain/fill procedure. Repeat this a total of at least 3 times and you'll have the majority of old fluid out of the tranny. ------------------------------------------------------------  <--Click Me!"As a lion is to a cat, so is a mastiff compared to a dog."

I guess the change is reccommended to get some particles out? Otherwise it wont really affect the current shift quality that I am experiencing? I am rolling 285 size tires over my 265 stock size, and was hinted at that this could be what has affected the smoothness of shifiting. Does that sound right?

You should NEVER flush a tranny. It will clog the toilet.

More importantly it removes the old burned fluid. Because of the effects of thermal breakdown on the oil, the properties (viscosity, lubrication) of this old fluid are not optimal for operating the hydraulics inside the transmission. Shifts get slow and sloppy, and things start wearing quicker.
If you see old burned tranny fluid pouring out of a tranny (pours like water) compared to the new fluid going in, you'll see why. Just doing a drain and fill a few times can drastically improve the tranny function. ------------------------------------------------------------ <--Click Me!"As a lion is to a cat, so is a mastiff compared to a dog."

werd to ur motha. That's encouraging. How about use of an oil other than recommended due to higher heat(az), additional wear(from not servicing) and desert/dune offroad use?

I haven't used anything other than normal Dexron III, so can't comment on that.

Thanks for the input! If I repeat 3 times, does that mean I have done the drain and fill 4 times total? Is your mortgage with Chase? PM me to find out how to refinance rate and term only, up to 125% loan to value. |

3 times total should be enough. That'll remove most of the old oil. Its a case of diminishing returns. You could do it more times, but you wont see as much improvement as the first 3 changes will give you.

If you want an "upgraded" fluid, there is a heavy duty industrial automatic transmission fluid that a lot of chevy guys use. I mention chevy, because Dexron III is a GM standard.
It's call HyTran, also commonly called "tractor fluid". Made by John Deere, it's sold at the auto parts store here, in 5 gallon buckets. It's automatic transmission fluid, but with some amazing properties. It withstands heat better, and it has a higher content of friction modifiers so your clutches actually hold stronger. Whats really crazy is that it's rated for hypoid gear lubrication. In a tractor, the rear diff, and transmission are all in one casing, and the same fluid lubricates everything. It's also used to operate all the hydraulics on the tractor. This is automatic transmission fluid you can also use in your differentials. Makes awesome power steering fluid as well! |

I have no idea. Thats also why I said specifically Chevy guys use it. Since they both call for Dexron III, I would assume it will be ok.
Don't blame me if the tranny shits the bed though. =) |
