Draining oil from Gear Box & Torque CONV

[drnas78]

Just been speaking to a local garage as need to change the gear box oil on my supra (auto).

 

I would like to flush the old oil as it is brown not sure what damage it has already doen, but the garage is telling me that they cant remove old oil from TORQUE CONVERTER.

 

Does any one know how to do this or is the a porcess that i need to advised them to follow for getting old oil out of the Torque converter.

 

Please advise

i always just drain the lot then refill and then just do some 10 miles changing the gears a lot by myself and then flush again

this always leaves the fluid really clean after 2nd flush

 

other method is just to sit going up and down auto shifter gears and then flush again there and then

 

i prefer the driving method as it means the whole box is mixed up so allowing a much cleaner fluid after 2nd flush

you can change the lot but you really need to find an auto box specialist as they know what they are doing, basically they remove the tranny feed from the radiator and that goes into a drum of new fluid, with the engine running the disconected

return line then pumps all the old stuff out till it runs clean, like i say this is a specialist job have a look in your local yellow pages for an auto box specialist, dont trust it to any old garage
