r2ck_p Posted March 15, 2015 Share Posted March 15, 2015 Hi guys, I am thinking of changing my gearbox oil, how easy is it to do? Any step by step guides around? I am comfortable swapping engine oil/filter and have also replaced copper contacts in my starter motor last year. This is my first auto car and I know that auto gearboxes can be pretty complicated, so was also considering taking it to Toyota to do. Planning to replace the cork gasket on the gearbox oil pan at the same time. Is there anything special that needs to be done when replacing the gearbox oil or replacing the gearbox oil pan gasket or is it simple enough for Toyota to handle? Cheers Quote Link to comment Share on other sites More sharing options...

David P Posted March 15, 2015 Share Posted March 15, 2015 (edited) If you're dropping the pan, fit a new filter whilst you're there. http://www.mkivsupra.net/vbb/showthread.php?92098-Auto-box-fluid-change-on-MKIV-com&highlight=auto%20box%20fluid%20change http://myautomatictransmission.com/diy-transmission-flush.htm Links to filters at sensible prices in the transmission group. http://www.mkivsupra.net/vbb/group.php?groupid=57 Edited March 15, 2015 by David P (see edit history) Quote Link to comment Share on other sites More sharing options...

I take it the filter sits inside the gearbox oil pan? So if I order a new oil pan seal, filter and obviously the Toyota recommended gearbox oil I am good to go. Is it worth replacing anything else while I am at it? Looking at the link I should need 1.9 litre of gearbox oil, does that sound about right? Could find filters or prices listed in the other link you sent. Cheers Quote Link to comment Share on other sites More sharing options...

Hi David, I have read your group posts, however the links you have provided are dead links. Please can you confirm the gearbox oil pan filters you have for sale and the price. Thanks Quote Link to comment Share on other sites More sharing options...
Scooter Posted March 19, 2015 Share Posted March 19, 2015 (edited) I have eBay item number: 291399326003 on watch re the filter (not bought yet so can't verify quality/fit) I would think about what you want to do, the easiest thing is to drain and refill (via dipstick) the 1.8. If the fluid isn't very red you could do this a few times in short succession accepting the fact that you are loosing some of the new fluid each time but knowing you are gradually increasing the % overall of good new fluid. Saying that it's unlikely the filter has ever been changed and so it's not a bad idea to do this, however you will still have to renew the fluid as again only 1.8L will come out on its own. I've been thinking that you must be able to detach a line somewhere and place a one end into a empty container and the other into a new 4l can of new fluid (i think you need 2 cans at least) and then start the car briefly to flush the new fluid into the system. I don't know the flow rate etc so it may be better to do it on the starter rather than actually fire up the engine etc but this is me just thinking of a way to flush the fluid in one go rather than 1.8l at a time. edit part of me would like to link the new source of fluid to the bottom of the rad and leave the dipstick alone?

I am watching that same item, but have the same concerns on quality and also it is unclear from the advert if you get the gasket to, it is pictured but no mention of the gasket in the advert. Would prefer a genuine Toyota one but don't fancy spending £74.44 + vat just for the strainer. I think I might get Toyota to do the drain/swap, dependant on what the quote.

Scooter Posted March 19, 2015 Share Posted March 19, 2015 I've become a little paranoid about getting others to do work on the car, luckily (or perhaps as a consequence) coinciding with me wanting to get my hands dirty. I'm not sure I'd trust them to use Type iv even if you asked for it! If your fluid is red'ish and not dark brown etc I might be tempted to simply change the fluid either in stages or completely as above.....I'm certainly in no rush to do the filter, it has a high hassle factor vs benefit ratio Quote Link to comment Share on other sites More sharing options...

But thinking its going to be a pain doing the gearbox oil change so tempted to take it Toyota. It looks like Type iv is the oil to go for, I know the parts guy, so planning to buy the parts and then taking them in to Toyota and get them to fit them. Hopefully this way they will use the proper stuff. Quote Link to comment Share on other sites More sharing options...
David P Posted March 19, 2015 Share Posted March 19, 2015 Some of the links may need updating, I'll see to it. The similar items button generally does it.. Quote Link to comment Share on other sites More sharing options...
