Is it possible to a DIY service on your Auto

Hi all - have a 92 TD27 Terrano we tow the boat with, started to
notice when approaching lights to stop the change down is not quite
as smooth as it use to be, keeping revs up as I go to stop makes it smooth.

Understand there are bands that need tightening from time to time ? Or would it be something more to do with the kick-down mechanism ?
(Its by no means running rough, very smooth on up changes)

Is it possible to do this yourself or do you need special tools ? Thanks

yes i was going to make a youtube video how to exactly.
Because every last video on therer is actuarly wrong, i have not found 1 video whom shows it correctly done.
the problem is you should not wait till you notice it is crapping it self and then think a service will fix it that only works on 90s corollas

What you should do is start the thing and pull the trans dipstick and mesure what the fluid level is with engine running is how trans is mesured
You look on stick has hot or cold markings .
This is for when the fluid is hot like on long drives it will be hot or cold level mesurment when its only run a short time.

fluid level must be within the markings or you must top it up soonest with correct fluid , most likely dextron 3 on a terrano
its not 1 liter usually just a small amount is missing if its low 1 liter with pull out hose is all you need. its filled thru the dipstick filler if you need to top up

when you mesure it inspect the colour of the fluid it should be nice red like a red wine colour if the fluid is in good condition.
also smell it if it smells burned then that is a alarm sign and it might be already to late because once you have problems driving it and burned smell often even after a service its getting rapid worse with the transmission failing no matter what.

if you dont know what dextron smells like buy a 1 liter dextron atf with pull out hose then you have the original colour and the smell of new fluid to compair what you have inside your transmission. supersheep auto ripco etc sell that with pull out hose , that bottle is also needed to when you diy service it. but that is a way bigger task new trans-sump filter , gasket band adjustments and flush refilling . and ultra clean working required.

never buy the one litre bottles with hose cost u a bomb lol use 4l packs .
find a plastic drink bottle that the opening will fit down your filler tube cut of bottom now u have excellent funnel

Why would you buy 4 liter ? you only need 100 mililiter at most and these pullout 1 liter ones you can refill after should you do a service and you know exactly how much fluid you add like this .
for a service you need 16 liter dextron as you have to flush the torque converter and cooler after service is complete. on a big trans like a terrano

Four words, Throttle Position Sensor Adjustment, if this is out or the sensor is faulty it can lead to odd trans behaviour during 'roll down'. Go see an auto specialist or a clued up diesel mechanic. While there get their opinion on the state of the fluid.

Op in answer to question, I believe not. The trans needs flushing as simp,y draining fluid won't get stuff in torque converter etc, this can be done at home with pipes and bottles and shit but it's a hella flaffel.
If you really want to do it find a video instruction for your car and it will say what's needed.
I took it in to get it done properly.

Yes easier to take it in to the correct place for service, they will have pressure pump to move the stuff around, any faults they will know whats happening.

Look Im sure you can drop the pan have a clean out and replace any filters, I dont know if there are bands to adjust in these ones or not , if there is you might need ft lbs tourque wrench and sometimes even inch lbs.But clean fluid and filter must be a help

Cheers all - looks like jury out on DIY - look forward to the video intrade

A legend in his own mind.

He got to be a happy man then

it will be a while as i got to learn how to edit video first haha as that video cant be made un-edited like all the other videos i made so far.
there is good videos on youtube but then they cut it short by not getting the old fluid out and all conterminate the fluid they just filled . again.
remember i had to learn all this stuff also no one was born knowing it all. i just hate it to see wrong or incomplete stuff on youtube.

Guess when you and mrs intrade going hard at it the camera has
to keep rolling .

If you just want to flush out the old oil the easiest way is to remove the return line off the radiator and put a bucket under it to catch the oil. Start the car and wait until the oil starts to splatter (running out). Stop it and put 4 litres of new oil into the trans and start up the car again and repeat the process until the oil is coming out nice and red. Depending on the type of trans it will take about 10-16 litres of oil to do this. (You should really remove the pan and clean that out and also replace the filter first)

here is how its done in steps
you run trans hot because hot fluid drains better.
then you put it on a hoist or on to 4 jack stands front can be ramps rear jackstands to level the vehicle as if it was on a hoist
then you open the trans dextron fluid plug and drain all fluid in to a pan
remove the sump bolts remove sump carfully often more fluid comes out . then you remove the gasket off the sump and clean the magnets in the sump and the sump sparkeling clean so you could eat your eggs from the sump dish . you put the clean magnets back where they where
you then remove the filter inside the transmission , carfull more fluids will come down usually. you then find the bolt that adjust the bands if it is ajustable.
the guy whom sold you the new sump filter and sump gasket should be able to tell you how to adjust that bolt or how to adjust the band .

then you fit the new sump filter and whipe any dirt off with a clean paper towl no dirt or fiber from any towl must enter the transmission insides
after carfully reinstalling the new filter and torquing the bolts back up to what they need to be tightened to you reinstall the clean sump and sump gasket .
then you fill the sump thru oil filler mesuring dipstick tube 3 to 4 liter dextron you will know because you use the 1 liter pull out hose bottle that you have 4 liter in the trans sump.

Now comes the part where everyone finishes or goes wrong.
You still have about 7 liter conterminated fluid inside the torque converter and the trans cooler
why in the hell would you now start the engine?
when all you need to do is remove the return hose of the trans cooler up front usually the lower part of the water radiator is the trans cooler.
You unhook the return fit a clear hose to the return of the cooler and poke it in a container where you can guess or mesure how much fluid comes out.
you then start the car best to have 2 people as you got to shut it down befor your sump runs dry again so after 2 liter dirty fluid is in your container from disconected return you refill another 2 liter in to the sump.
and do the startup again for purge of more conterminated fluid.
You do this untill your return fluid is nice and clean dextron.
usually 12 to 16 liter dextron total is required to purge it all clean .
then you reconnect the hose and mesure the fluid in sump and then it goes back to the videos on youtube how to top it up cycle thru gears with foot on brake and re-mesure fluids . then go for a test drive and then you have to retighten the bolts on sump as the usually cork gasket now is soaked and you cant tighten a cork to hard it will split the gasket you just have to retighten all bolts carfully again. sometimes you have to retighten them again a week after. if its diy and your own car as you dont want to split the gasket.

differentthings read my instruction its a bad idea to run a pump dry. i only tell save and diy-professional methodes i dont like dangerous methodes and when it sputters then its run out of fluid and that is a no no as you dont know the long-therm damage you might have caused doing that.

the most easy way is when you now know how its done to have a professional place do it the refilling part can be done quick with a 7000$ flushing machine . but you do not wan to have some moron with his flush machine just flush the fluid as the service and charge you for it . So be carfull about that gungster practice . if the price for the trans service is to cheap then they probably are not doing it correctly .

It's fine. Done hundreds and never had a problem. Might be different if you leave it running for a hour or so.

You assume its fine just because it has not destructed instantly does not mean it did not do damage. You dont drain your engine oil and then run the engine till your valve lifters make a noise to make sure you got all out out now do you? its the same thing you wont know if you done damage or not its bad practice to assume because it did not blow up instantly that ist be fine . but hey you do it your way i only endorce 100% save practice .

If you have ever stripped down a trans you will find that there is plenty of oil left to lubricate the bushes, pump gears etc even after running it dry. I will rewrite it for you.
"As soon as the oil splutters (ie shows signs of air turn it off).It is really a 2 person job."
It's the same as you can tow a auto for a short distance with damaging it. yes I know it is different as in the pump is not working,but the principle is the same. I only worked for 20 years rebuilding the things.

Its probably just the TPS adjustment.

differentthings
i dont like to argue but you fail to understand why i dont do it your way , loads of other stuff also requires this way of thinking . Its like the shroedinger equation. if you understand that one then you will see things differently and find actuarly problems quite quickly because you think of all the possible and impossible causes and reasons befor you start doing anything .
I dont say your wrong i say you cant proof that it wont damage the gearbox just like the shroedinger equation. And i cant proof that you should do it my way .

is the shroedingers cat dead or is it alive?
