Gearbox oil change

Post by **Donald** » Sun Oct 06, 2013 11:02 am

I was thinking the Prelude could do with a bit of a freshen up as I've not changed the gearbox oil and I probably should!

Box is currently on ~125k and doesn't crunch any gear. I'm not sure what oil is currently in there although I would assume it'd be Honda MTF.

So my question is, just draining the box and refilling with Honda MTF shouldn't present a problem? Or would a full change be preferable? IIRC the box holds around 2L but the whole system is closer to 6, so quite a price difference especially if a switch to Torco or Amsoil is the answer.

The manual gearbox only holds 2.2 quarts of fluid. It needs only 2 quarts for a fluid change. A quart is 0.94L.

And yes Honda MTF, Torco MTF, or Amsoil MTF are the 3 you should choose from. I have found Amsoil to be good and have used it for many years.

Changing the fluid is easy. Always slacken the filler bolt before you empy the old fluid

once the car is jacked up all you need is a bit of hose an a funnel. As soon a fluid comes out of the filler hole the gearbox is full. Two bottles of Amsoil is the exact amount needed.

Don't drain the box without making sure you can fill it back up! Fill back up with the aid of a long hose from the engine bay.

Cheers chaps

Went for Amsoil from Opie Oils in the end, worked out only a tenner more (inc. delivery) than Honda MTF from Cox Motor Parts, even with 20% off. So why not I says.

EDIT: Fecking forgot about the LG discount
