V160/161 Gearbox Oil

Recommended Posts

Right then, here's hopefully the final nail in the coffin of anyone who thinks they can stick any old oil in the V160/161 6-speed gearbox.

 

I've, as you know just got a new Sup, it went for it's first fluid change at the weekend (Engine, Gearbox and Diff).

 

Firstly the other bits;

The Diff now has in Silkolene Syn 5 75w-90, the oil that came out was in good condition and no signs of having got too warm. No difference in it's performance since the change and so I think it had good oil in there. :thumbs:

 

The engine - now filled with Silkolene Pro S 10w50 - was getting an oil pressure light for a split second on start before the change tis now perfect - was prolly just little low. The oil that came out was Black but a clean shiney black if you know what I mean. No debris, petrol or other contaminents. :thumbs:

 

Then it was the turn of the gearbox. Problems to date. Now I know the V160/161 is clunky but even Superman couldn't get it into 2nd gear when cold. I'd have to use 1st and 3rd for the first 3-4mins and then I'd be able use 2nd just and only when it was hot would it work well.

Cracked open the inspection port (car was level on a ramp) and oil pissed out of the inspection/fill hole. 100-200ml's too much at least...and it was yellow/gold in colour. V160 oil is RED. I'm not sure if over filling could have been responsible for the crap change when cold but I do know it could have lead to me blowing a gearbox seal. Great :(. Next obviously the actual drain hole was opened and all the (thicker than V160) cr@p oil was flushed out. Replaced with V160 oil.

 

At ~£30 a can (you need 2) this stuff is not cheap but boy does it work. My gear change problem is gone. The gearbox is as swift and direct as I know them to be. Just fingers crossed that it's potential years of abuse won't have hurt it too much.

 

Manual 6-spd Supra's NEED V160 oil!!! DO NOT COMPROMISE!!!

Thanks Alex, have ordered some from Toyota now!!

 

Must admit since the silkoline oil went in the gearbox has been difficult to get into 2nd (though quieter than before the oil change as there was less than 0.5l in it!!).

 

Anyone want to buy any Silkolene Syn 5 75w-90? got tons of the stuff I'm not going to use now!!

totally recommend this for Diff oil (auto or manual) If you have loads spare advertise it in the For Sale section. It takes 2 bottles to do the Diff...

Well said Alex. I second that after being flogged some other sh*te from a trader on here no less :devil:

 

Swapped it for V160/V161...made gearchanges smoother (especially from cold) and quietened down the box. Had to give Toyota the correct part number for the stuff though.

Sorry I didn't mean flushed as in ran something else though it....just meant it was left to drain for a long time and then filled up with V160...

 

But if you were to flush it then you'd need much more V160 as it's the only thing that should touch the internals ;)
