I've got a TZ102ZA4BA AT. Does anyone know which AT cooling line is the return? I'm going to flush the tranny and I can't find this one piece of info.

Thanks in advance

The top little line flows transmission fluid to the radiator/cooler and the bottom goes back to the transmission.

Thanks Strakes!

Get a clear 3/8 plastic line. You can pull the bottom radiator trany hose, to flush the radiator cooler as well. Put the line from the radiator into a gallon jug (see through).

 

Drain, then fill the transmission with new fluid. Start the engine, let a couple of quarts pump out. Stop the enging and refil the trans. Keep doing this until clean new fluid comes out.

 

If your quick or have help, you can shift the trans through all the gears while its running and keep on filling the trans as the same rate as the old fluid is coming out.

 

Just don't run the trans out of fluid.

Thanks Imdew, Thats what I intend to do. Except I'm using a 5 gallon pickle bucket and a gallon bottle of ATF. I'm have a torque bind issue with the car and I'm hoping a good flush will help. I'm going to need to use the car soon so I want to get this done. Thanks again.
