So now after utube and the tech stickies on here I need to know what the actual recommended fluid is for a transmission oil change.


I've heard tranny fluid, gear oil and manual transaxle gear lube


What does the factory service manual call for. (haven't got a service manual yet). I will use good quality synthetic but what is called for?


Thanks in advance.

You didn’t mention what version smart car you own. 451 or 453.
This is what you use, in the 451 smart car.

Oops yeah the 451. Thanks. So just gear oil. 75-14? Hard to see in the pick.

This is what I used. At around $18 a quart it's not cheap. The good news is you only need to buy three.

I'm sure the amsoil is great but you cant buy it off the shelf.

I did at Advance auto parts. At least in Texas, USA you can. I'm not sure if it's available nationwide or in other countries though.
