roscodav Posted November 3, 2003 Share Posted November 3, 2003 I have been searching around the forum and think I know what I need but a> want to double check, and b> have a couple of questions. For note 93 J-spec TT with Auto box My trannie fluid is nicely cooked (brown and smelly) so time to change. I am happy to do a few fequent plug drain and top ups to be on the safe side. So basically.... 1> Jack the car up on axle stands and remove plug from the bottom of the transmission and let it drain (expecting about 2 litres. 2> Replace plug and pour new fluid in through the dipstick hole?!? of about the same amount as was removed (on the assumption the levels were correct to begin. 3> Check level doing the every gear jiggle thing and with engine running. 4> Check again in a day or so. Fluid to use is ATF T Type IV. On the assumption that is all correct and I am sure I will be corrected if not, where on earth do I get the transmission fluid. I have been to Toyota who say that they only have it in huge drums and they would have to do the work (2 garages), Halfords stock Dextron II and III and ATF DII, also a few Castrol ones that I didnt remeber the details and Motorworld stock some other brand that say ATF-Q ATF-G. Also do I need a special tool to get the drain plug out? And finally...... I want to change the diff oil also but know very little about that. I assume it also have a drain plug but where does it go in and what oil (and again where do I get that from). Thanks in advance. Quote Link to comment Share on other sites More sharing options...
Steve W Posted November 3, 2003 Share Posted November 3, 2003 DEFINITELY Toyota Dealer ! ! ! YES, the Type IV - it comes in 4Litre cans. I'll get the part number off the can....... NO, they DON'T have to do it ? - (certainly not the 'partial' changes as you're gonna do.... which is exactly what I do.... done 2 in past 6 months, will do another soonish = nearly a 'whole'-ish change:p ) to do a 'complete' change is a little more complicated, so I DIDN'T ! that may be better done by a garage ? Diff'... don't know ? - still haven't done mine:( FatS. ps. sorry... NO, no special tool Quote Link to comment Share on other sites More sharing options...

roscodav Posted November 4, 2003 Author Share Posted November 4, 2003 Thanks for that. I phoned 4 different Toyota dealers and was presented with a number of options and none of them found the right one.. even with the correct part number!!!! I even got as far as going to one that said that the part number had changed and they had the correct stuff. When I got there the presented me we a white can of ATF Type T but everything else was in Japanese. The only thing that I could back out was the number 3. So I decided not. Frustrated I phoned my local Lexus garage who, despite denying that they have every had anything to do with the Supras, said oh you need Type 4 come and get it. First time, no hastle whatsoever. To top it all when I got their their system has "lost" the code for the 4liter tin so he could only charge me the 1 litre price. Bargin! So now it is time to lie under the car in a puddle!

dude Posted November 4, 2003 Share Posted November 4, 2003 If your fluid is brown and smelly you may want to think about a proper flush and filter change either that or a bank loan to replace your knackered gearbox , im having my box uprated soon so will have a price for a rebuilt uprated auto trans that will hold up to a single turbo Dude:flame Dev Quote Link to comment Share on other sites More sharing options...
roscodav Posted November 4, 2003 Author Share Posted November 4, 2003 Well I am now very wet after sitting in a puddle in the pooring rain. but I have done it. I will do another one soon ie the weekend unless someone says to leave it longer (waits for comments). This I should hope will at least help until...... Taking Dude's advice I plan a full flush in the next few weeks (depending on how long it takes to get the 16l of ATF. I have had another search around and the following method is mentioned that seams like a good plan. Unless once again someone either has a better idea or screams for me to stop as I am about to blow the auto box... I await the comments...... http://www.bestsyntheticoil.com/amsoil/torqueconverter.shtml Quote Link to comment Share on other sites More sharing options...
eyefi Posted November 4, 2003 Share Posted November 4, 2003 good method u can get auto specialists to do this for u, they have equpment that makes it easier, just make sure u supply the correct type t-iv fluid. i think alot of autos r close if not overdue for a full flush. just changing part of the oil over and over again is just diluting the crap fluid and, imo, throwing money away. u dont need to buy a new filter, the one inside the box is a metal mesh type strainer and can b cleaned. they cost a fortune from toyota.

dude Posted November 4, 2003 Share Posted November 4, 2003 About £57 , still cheaper than a new box though dude:flame Dev Quote Link to comment Share on other sites More sharing options...
eyefi Posted November 4, 2003 Share Posted November 4, 2003 dude, what u doing to yr box, the americans usually replace em with some gm box. Quote Link to comment Share on other sites More sharing options...
dude Posted November 4, 2003 Share Posted November 4, 2003 The yanks are using the TH400 , excellent box and will take Mega power but only 3 speed , im having the stock box rebuilt using better stronger faster (sounds like the 6 million $$$$ man) parts and an uprated valve body with a hi-stall converter , i reckon on my stock turbos with drag radials the car would run mid 11's , shame that by the time the drag racing starts next year i'll be running a single but i have a crash test dummy with a converter thats up for running so we should get some times as i'll put my DR's on his car Dude:flame Dev Quote Link to comment Share on other sites More sharing options...
Terminator Posted November 5, 2003 Share Posted November 5, 2003 There was some debate about the pros and cons of repeated flushes due to the minerals in the fluid being deposited on the internals in the box. Too frequent change of fluid could alter the deposit rate and actually be bad for the box. The debate got cut short due to other issues.

eyefi Posted November 5, 2003 Share Posted November 5, 2003 i cant see any need for repeated full flushes. once its done the service interval partials should b fine. unless yr powerbraking alot. Quote Link to comment Share on other sites More sharing options...
dude Posted November 5, 2003 Share Posted November 5, 2003 Problem is getting all the old sh**y fluid out as it like to hide in the converter and even with this out its kin hard to get it empty Dude:flame Dev Quote Link to comment Share on other sites More sharing options...
Steve W Posted November 5, 2003 Share Posted November 5, 2003 I know what you mean Phil.... but I'm only doin' a few (3/4 ?) enough to 'sort-of' change the whole fluid.... ( ) I'm just a lazy B' and don't wanna mess with the pipes ! ! Quote Link to comment Share on other sites More sharing options...
Need4Speed Posted November 6, 2003 Share Posted November 6, 2003 unless yr powerbraking alot Don't use the transmission to do the brakes' job. If you need to do it to slow the car, uprate the brakes. Quote Link to comment Share on other sites More sharing options...

If you need to do it to slow the car, uprate the brakes. That isn't what powerbraking is about. You use it to get a hard launch. When stationary foot HARD on the brakes and build the revs up, at about 1500-2000 RPM the back end will start bucking and maybe wheelspin if you go too far. Off the brakes and floor the throttle and you'll get a great launch. Do a search for drag starts I think. Too much and holding it for too long can kill a 'box.

Need4Speed Posted November 7, 2003 Share Posted November 7, 2003 Ah, I see. Not being a drag racer I wasn't up on that one. I stand corrected. Quote Link to comment Share on other sites More sharing options...
