kasiunqa - czemu w twojej odpowiedzi są oleje do 451 i 454 ? Czy Evilution zaleca je do skrzyń w tych modelach.
Z tego co piszą w internecie do tych modeli jest inna specyfikacja oleju niż 236.14

skopiowałem to co oni napisali do 450 i roadstera tu masz całość

The 450/Roadster Transmission Fluid Confusion

If you ask on any forum what transmission fluid should be used in a 450 or Roadster,
you will almost certainly be told ATF (Dexron III). However, this information could be wrong.

It seems strange that although the 450 gearbox is a manual the same as the 451, the
specced transmission fluid is different? I have contacted Getrag but have had no answer.

However

Smart's own workshop instruction system says that the 6 speed transmissions found in the fortwo
and Roadster are covered by document BB00.40-P-0236-14A which states the filing capacity of
1.4 litres of ATF listed in Sheet MB standards MB 236.14

The other information that I can't ignore is that ATF is red and that all transmission fluid I have changed
in 450's and Roadsters is also red when it came out. Dirty as hell but still red. Standard gear oil (as
recommended in 451's and forfours) listed under MB 235.72 is a normal golden colour which ties in
with what I have seen after changing the transmission fluid on a pair of 451s.

Stick with ATF for the 450 as it has worked so far.

Franz M contacted me to say he has used BP Energear SHX 75W90 in 6 smarts (fortwo 450)
over the last 3 years with no problems even though smart recommend ATF.

Extra Info

The oil rating for gear oil is different to that of normal engine oil.
75W90 gear oil has the exact same viscosity of a 10W40 motor oil.
This doesn't mean you should use 10W40 motor oil but you could in an emergency.

Engine oil is a lubricant and transmission fluid is a hydraulic fluid with some lubricational properties.

Drain Or Fill Plug Is Seized

Top Plug

If the top filler plug is seized then I it's probably best just to leave it. If you absolutely have to
top up fluid that is leaking then try spraying it in penetrating lubricant like PlusGas, leave it for
a few hours and try again. Heating around the plug can aid in the removal. As a last resort you
can grind a slot into the plug and attempt to remove it with a hammer and an impact driver.

Bottom Plug

If you can remove the top plug but not the bottom plug then don't worry.
Instead of messing about attempting to remove the seized plug, simply leave it in.

Take the oil removing pump you use for servicing (Pela 6000 for example), push the flexible hose into the top hole and pump as much of the fluid out as you can.
You will be able to remove a large majority this way.
If you jack the front of the car up you will get more out as it pools nearer the back.

Once you are happy you got most of it out (you will be able to see the removed fluid capacity
on the side of the tank on the Pela 6000), use the top hole to refil as you would normally.
