i am taking my lx470 in for a tranny fluid change.

i am understand that they just do they drain and fill technique. but how many times do they fill and drain?
i was just currious.

thanks

 

typically with just a fluid change, its just once. draining the pan, and refilling it... it takes about 3.25 quarts. if you're getting a fluid flush, thats a whole different idea, but its not something we do at my dealership. regular fluid changes, at 3.25 quarts each, is plenty preventative maintainence...

 

so wouldnt just one drain not get all the oil out?
i was under the impression that one drain wont get all of the old fluid out.

 

A drain and a flush are two different things.

Flushing requires about 19 quarts of fluid, they drain, and refill several times so as to get all the old fluid out of the transmission and torque converter. With a drain, your gonna still have roughly 30%-50% old fluid remaining.

 

my drain and fill took 2.8 quarts, out of 12 total.

 

how do you do a tranny flush anyways? also is there a filter for the tranny?

also where is the tranny drain plug?

 

so the tranny flush does it come with a new tranny filter and how much is it from lexus ???

 

I thought the trans only has a screen that does not need to be replaced.

 

Correct, the screen doesn't need to be change.

They use the trans flush machine that hook up to the transmission cooler lines at the bottom of the radiator. After the tech hook up the trans cooler lines to the machine and start the car, now it bypass the trans cooler and all of the trans fluid that come out of the transmission will go through the flush machine( inlet side) instead of going through the radiator. The old trans fluid will be correct in the drain tank.

The machine will pump in the new fluid back into the transmission.

 

there is also another machine that hooks up to the cooler itself, and flushes any debris out of it by running fluid through it, into a filter on the flush machine, and putting clean fluid back in it.

 

so there is no tranny filter ?? and how much is the flush from lexus ????

 

my dealer charges $80 for fluid change. not flush. I just had it done at 22k miles(because the car is an 01 and also I was having a new diff put in via warranty. So I paid $80 for a $3000 job.

 

I have no idea how you consider a tranny fluid change being worth $3,000. Dont consider the new diff. a $3000 thing, it was free, and was covered under warranty.

Yes I know if you WERENT covered, it would have been a ton.

 

Alright, how's this- Since I was getting a $3000 warranty job done for free on a car I bought used, I didn't mind giving them $80. I would have paid $80 with no tranny fluid change.

 

My service advisor at the dealership told me they have a transmission flush machine, but when I called last week to make an appointment for a flush I was told that they DON'T have a flush machine . So now I don't know where to take my car for a good flush. Does anybody have any recommendations???
