Hello chaps,
I have just done the Auto Transmission Filter change on my 100 IFS.
I have done about 90,000 Miles and I never knew that a filter existed in the autobox which is supposed to be changed every 25,000 Miles. Now a friend of mine who drives a E240 Merc, had experienced slippage on his auto box and a very experienced mechanic (Rally Driver) said that if we change the filter and oil, the problem might dissapear, if the car has not been dragged for too long.
Surprisingly when he changed the filter and oil on the Merc, the problem went away, Its as good as new and no slippage remains.
I had no slippage on my LC100 IFS, but, I thought that if a filter system exists in my Auto GBox, I cannot take a chance and need to change it immediately as I have never done so.
So, Pics below will hopefully show the process:-
First, buy a filter from toyota original part.
This is what it looks like
You must ensure that no dust or dirt can get onto the gearbox when open, so turn off all blower heaters when working. First drain the Auto Trans mission and leave it overnight to empty completely, Remove the under guards and then open the 19 bolts holding the sump to the gearbox and you will see the sludge at the bottom with 4 magnets,
The filter is a metal one and its held by 4 bolts and looks like this
Undo the 4 bolts and remove the filter from the gearbox, mine looked this filthy
Refitting is a reversal of the removal, but, you have to clean off the old sealant, Ensure that you have a clean tray or some sort of pan in which to clean the sump pan, we used a mix of diesel and petrol to clean all the sludge and the 4 magnets at the bottom of the pan were also cleaned and all shards removed with a dry tissue, The gasket on the sump must be removed very carefully, with a blade and a circular wire brush is what we used, got some light scratches, but are easily covered with the sealant
I used Wynnes gasket sealant, capable of handling a temperature of 236 Deg Cent. Toyota wanted to sell me a sealant, which alone would have cost £70.00, this is also pretty good

then put some ATF in it once it dried off.. Have a good look inside and you can see if it's blocked anywhere. The outside and bottom of the pan do get pretty gooky, but I don't think that affects the overall running that much. It's probably more a strainer than a filter in reality. Obviously blocking the strainer will make a difference.
