Hello Fellow FJ'ers

I hope you are all well.


Am fairly new to FJ but know a bit about cars in general. I will try to make this as short as possible:
I want to flush my FJ's Transmission, After a lot of youtube and google searching, also reading manuals I have decided to do it myself.
I have everything I need (tools, replacement parts and etc) but I will wait for the experienced people answers first.
the way am thinking of doing it is as follows:


1-Start engine and put gears on N
2-wait a while to heat the trans fluid 125F approx
3-disconnect the trans hoses from cooler (near radiator)
4- put coming hose into a bucket.
5- connect the going hose to (MityVac) vacuum. the Mityvac contains 5 quarts of WS trans fluid.
6-mark draining bucket level for 5 quarts.
7-pump fluid inside trans by Mityvac while the other side is draining in the bucket till all 5 quarts of new fluid replaces the drained 5 in the bucket simultaneously.
7-turn off engine, drop pan replace filter put pan back and torque back everything after cleaning the pan etc.
8-start engine wait for heat to reach 125F
9-open the fill plug in the trans body, add or remove according to the specs.


please let me know if there is anything wrong with this procedure. especially the cooler hoses disconnect and the pumping technique.



your comments/advises are highly and sincerely appreciated.

Your plan won't do a proper flush since an automatic tranny holds 12-14 qts. A lot of fluid is in the torque convertor which won't be touched unless the truck is running.

I would do a simple drain and refill a few times until fluid is clean.
