I have edited your post for you... Thank you for your magnanimity, nevertheless, 62 out of now down to 535, kind of proves my point! Yes I am "passionate" about this Global issue, that apart from recognition by Gaz6002, apparently doesn't exist with Club Members, or is being ignored by addicts? Guess which option my pint is on!

Bin those cheap aftermarket discs and replace them with OE.

Whilst you are waiting for an alternative ECU to try, have you looked to see if your present ECU has thrown up any fault codes? How-to here... https://www.mkivsupra.net/vbb/showthread.php?35920-How-To-Check-the-diagnostics-codes

I can't see why, all pre Face-lift TT Supra's have a non VVTi engine which is the same as a Face-lift non VVTi engine? An ECU plugs into the engine, not the body trim.

One and the same.

You may have seen some with those figures as an asking price, but I challenge you to name someone who has actually paid that? Such things are difficult to know unless you are in the know, because it's fashionable for Twisted Dipsticks to delete even the asking price from their ad. This one totals £730; plus the price of the dipstick, dipstick tube, flex-plate to crank bolts and flex-plate to torque-converter bolts? The going price for a complete TT automatic transmission is around £200 as a spare for those who don't need one and up to £300 for someone who desperately does because he was too dim to have a spare. Which makes this one total around 4 times the usual price. Don't take my word for it, have a browse of all the auto boxes for sale that I have linked in the Transmission Group. https://www.mkivsupra.net/vbb/group.php?discussionid=86&pp=10&page=3&do=discuss (Please note that you will not be able to open this very smart Group page with a Not-so Smartphone.) Maybe it makes it easier for Modern Men Supra owners to recognise each other at Japfest?

You forgot to state how many hundreds of pounds you want for the dipstick? FFS

Maybe it's an "agreed value" thing?

Toyodiy say's... Part 22270-66010 (VALVE ASSY, IDLE SPEED CONTROL(FOR THLOTTLE BODY)) was found on the following models: Date range Model Frames/Options Found in diagram 01/1990-12/1997 TOYOTA LAND CRUISER FJ80,FZJ80 22-11: FUEL INJECTION SYSTEM 01/1990-12/1997 TOYOTA LAND CRUISER FJ80,FZJ80,HDJ80,HZJ80 22-11: FUEL INJECTION SYSTEM

In the likely event there is no improvement, before you start chasing wild geese, it would be prudent to next try an alternative ECU?

Thank you for resolving your technical thread. For the benefit of others, I have added this to the Transmission Group's collection of disgracefully few threads that have been resolved.

Try another ECU and find out?

If you gave the box a "full service less than 2,000 miles ago", how could you not know? I have never before come across a box that is not working properly because it had been overfilled, but whatever may be wrong with it, getting the ATF down to the correct level is the first thing to do. The fluid looks to be in far better condition than I find in most boxes that are working properly. Consequently, I wouldn't waste any money on new fluid or encourage someone else to, until later in this diagnostic guessing game.

Club Motto

As I said. There's nothing wrong with the fluid. Please don't do this! If reading an automatic transmission dipstick was part of the driving test, many folks on here would still be catching the bus. Drain the sump into a clean vessel and you will find that because it has waaay too much, around 4-litres or maybe more will come out? Beg borrow or steal a ladies stocking and then pour a measured 2-litres of it through the stocking back into the spout. Dipsticks are now informed how to survive without learning how to read a Supra transmission dipstick. Re-using perfectly good ATF is perfectly good common sense. This information and lots more is all available and clearly indexed in the Transmission Group at the mere click of a button. (Please be reminded again-again that Group pages do not function with Smartphones) All folks need to do; is turn off their not-so Smartphone and turn on their brain!

Why would you need to buy more ATF when your problem is having too much of it? If you read the information in the link that I gave you, we can put the spoon away for a while.

My age is definitely an advantage over this Modern Men's self-inflicted affliction-addiction. It is also definitely an advantage with my reading, writing, concentration and comprehension abilities too. Have you even bothered to read the facts of this growing International concern that I have researched and linked? Only idiots and/or Smartphone addicts will deny these! I'm neither, please let us know if alternatively, you are either or both? Should you wish to make further idiot, addict or even rational comment, please don't snide it here, stand up, grab yourself by the balls and post where it won't be off topic. https://www.mkivsupra.net/vbb/showthread.php?359910-Rising-Use-of-Smartphones-amp-Falling-Use-of-Forum Thank you.

Spoilsport. P.S. Your Nomophobia is showing.

There is waaay too much fluid in that. (At least 2 litres?) Nevertheless, the colour of the fluid indicates that the clutches are not slipping and the box is not overheating for any other reason. Trying to diagnose a fault like this from descriptions by un-mechanically minded folk, is a nightmare. Drop the fluid down to the correct level and if that doesn't magically fix it, take your Supra to someone in the Real World who knows their onions. P.S.
