recommendation ATF for worn out clutch pack #4713692

Hello,

I have 4l60e transmission that leaked out all trans fluid (rusted cooler lines) and likely has worn out clutch pack and seal.
But it still runs but there is a delayed engagement @ 3-4 and just a little jerky on the 1-2 (depending on timing and acceleration), kind of annoying more than anything else.

I want to do another ATF full flush and filter change, but want to experiment a bit to get (possibly) a little smoother shifting. I already changed the solenoids on it.

Do you recommend Dexron 6 blend or full synthetic in this case? And perhaps lubeguard additive on top?

Thanks

You could try the spec ATF and a bottle of LG red. It might help a bit, although if the parts are actually worn out I think you'll eventually be looking at a rebuild.

LG has the 32oz, the 10oz and 2oz bottles.

the more the better?

Maxlife and LG red, the BITOG transmission elixir.

I assume he meant whatever atf is specified for your vehicle. Depending on age dexron 3?

I know how those shifts you describe feel, especially that 1-2.

NO ATF fluid in the world (NONE) will fix a worn clutch pack.

thanks, and it's a 2007.

I'm not sure if it's a myth or just plain misinformation, but I have read that fully synthetic ATF can be "too slippery" for the clutches.

Is that true? would it therefore be beneficial not to use fully synthetic if the clutch pack is (slightly) worn and therefore more friction the better?

That is not true.....the add pack will determine how "slippery" the fluid is.

You're probably fighting a losing battle here, but I would skip the Dexron-VI and go with a thicker fluid, like TES-295 and add 16 oz. of LubeGard Red with it. The esters in LubeGard might help some, but it's no guarantee.

The 10oz bottle is good for most automatic transmissions. You can shoot them an email and they'll give you a dose/per quart of ATF, then base it on the transmission's capacity.

If the clutches are worn out or missing friction material its a done deal. You cant fix broke.

I have read that the old Ford style fluid is thicker and can help with low pressures and slow shifts.


Don't waste your time on a slipshod repair.

Yes but it won't replace worn out material or a unit in need of a rebuild as I alluded to earlier.

Is the 1-2 hard shift a bad sign? I have a 2000 Silverado same transmission, with the same feel 180k Miles, and a rebuilt transmission about 60k ago.

Maxlife ATF and Lubeguard Red. What have you got to lose? Won't fix it but it will make it more comfortable until it expires grin
