3.3TT Trans flush and Both Differential oil change

[Kodiack]

Just finished both Diffs oil change and a double trans flush.
3 bags of AMSOIL 75W90 severe gear and 10 liters of Valvoline maxlife multivehicle.
It took around 3 hours but almost 2 was just the front Diff..its hard to find the fill port.
I used a headlamp laying on top of the sway bar just on the passenger side of the oil filter housing and it lights the fill 8mm hex perfectly if you look between the diff and steering rack, once located it was fairly easy with a 10 inch extension. I removed my forward under skirt and everything was easy to get at from behind the rad.
All the drains and fills are thread locked so they were in there pretty good. I used the hose from my fluid extractor to refill, the AMSOIL nozzle fits it perfectly.
For reference I have 105k kms but I have no mods and drive like a grandma, none of the fluid was nearly as bad as I would have imagined.
I have a set of quickjacks I made a set of adapters for the stinger, made it much easier than jacks. Lifts the car about 30 inches.

Stinger requires 75w85 differential oil and sp-iv rr oil for transmission. RR part is important, since it is not compatible with sp-iv. Don't know if valvoline meets the specs though. Totally agree on the front diff. Total pita. I unbolted sway bar bushing brackets. Made it litle easier.

 

[Kodiack]

You are correct, it calls for 75W85 but 90% of people use the 75W90 amsoil severegear. Difference is minimal, imho.
And the Valvoline Maxlife is fully compatible with RR, its not on the container its in the spec sheet.

Looking at the Valvoline page, it looks like it's compatible. Multi-Vehicle (ATF) Full Synthetic Automatic Transmission Fluid - Valvoline Go to the Multi-Vehicle PI Sheet, then scroll to Kia.

For gear oil first number before the W is viscosity cold, second is viscosity hot. So 75W85 has a lower hot viscosity but the same cold. Very little difference between the 2 grades.

On the trans, how many drain/fill/run cycles did you do? How much fluid did you get out at every drain?

On the trans, how many drain/fill/run cycles did you do? How much fluid did you get out at every drain?

I did two, it was so clear after the second a third wasnt needed. It took about 8 liters in total but after I finished I went for a drive to heat the tranny up to temp to do the final level check and about a 1/2 liter came out the level drain after up to temp. I bought 2 5 liter (gallon) jugs and a couple single quarts so I would be covered for 3 if needed. So I would guess each cycle requires little over 3 1/2 litters/quarts.

Thanks man. I plan to do mine soon, weather permitting.

oh, so it doesn't actually take over 9L, but it recommends that much because you have to waste some of it for using as a flush system ?
If that's the case, wow, what a waste of money on fluid. It's not cheap to buy that many liters. I guess it's part of the process to get it cleaned out.
So when you drain it, does 90% or more of it actually drain out on the first dump ?? If yes, Hmm..., Wonder if that's the case, whether its safe to use cheaper tranny fluid for the flush process and then on the final fill, you use the good stuff ?? I just bought the Amsoil signature tranny fluid.. but if my suggestion above is good and you'll only have the good stuff in the last fill, then rest can be save for next one, or share with a friend or for another car of ours.
Feedback ??

It takes about 5 quarts for transmission drain and refill. Add another 0.5-1 quarts if you replacing transmission pan/filter.

It holds 9.2 liters or 9 quarts, but only about 4 is in the pan the rest is in the transmission and cooler and cant be emptied. Thats why it needs to be filled and flushed a couple times to ensure most of the old fluid is replaced. I used the same valvoline max life multivehicle for the flush and refill, but mine wasnt that bad after 100k kms of 95% highway driving. I did a double flush anyway because I bought enough for 3 flush cycles.

I agree, I did mine at about 43K miles since I race it now and then. The old fluid that came out on the first drain looked brand new.

o.k. so you top up, run the car a bit to warm up and then drain it to get rid of more mixed new/old so when you finally top up, mostly new will be in the mix.
I'm gonna buy a few quarts of regular Cdn tire tranny fluid and ask them to do two fill and drains running it, and then top of with Amsoil, so at least half is Amsoil and half is New but not amsoil. seems like a waste to use costly Amsoil if half or more will get drained out on the flushing process.

Get tranny warm, drain pan, Fill until it runs out lvl check plug, get tranny warm, drain pan, fill until it runs out lvl check plug....repeat if necessary.
Just make sure on the last fill and warm up you remove the lvl plug so it drains excess to the correct warm level if not it will be a little over full. It takes about 4 liters per cycle.
I would not use Canadian tire brand tranny fluid, no fluid of that brand meets specs for the stinger and you cannot ensure none of it is left. If want to use a less expensive fluid for flush make sure it meets the SP-IV-RR spec.

Just remember, you top off or check the level with the engine running.

o.k. thanks for this. I'm getting a shop to do it, but I'll make sure they are going to do this method. I Have Amsoil Signature serious, but I also have their O.E., version (which both of these show the SP-Iv-RR spec), for my stepdaughters car, so I'll use the O.E. Amsoil fluid for the flushing part (much cheaper but still high quality fluid) and the final top up with the Signature for both our vehicles.

You don't need to change the transaxle fluid. Owners manual says, "No check, no service required", and the TSB says only went replacing it is this necessary.

^^All fluids break down over time. Refreshing them periodically prolongs the assembly life said fluid is lubricating.

Cheaper to spend some $$ on fluids than $$$$$$ to replace the transfer case.

That's called planned obsolescence.
