pumping out tranny fluid tool?

[Cyprs]

I am driving into city today to get some gear oil and might buy a transmission fluid pump too, I read in here on pumping out transmission fluid rather than dropping pan, are we talking a Hand Pump syringe type plastic tool? Does on use this pump on transmission fluid lines?

thanks,
Cyprs

For my cars I use the "cooler line transfer" method. It uses the internal pump to flush old fluid out by disconnecting return line from the cooler, and running the engine. Of course I do drop the pan on the first transmission service.

Complete detailed instructions are at Amsoil.com.

You can get a suction pump they use for gear oil. It looks like a grease gun, just get a longer tube, it works well, especially if you don't want to disconnect transmission lines.

Will check Amsoil's site out Jorton, thanks.

Demarpaint, I actually have one of them, I used it for filling my difs, manual transmission and mixer gearbox, rather than putting tube into gear oil container, extract from it and fill I use this thing to extract fluid out of transmission sump via the filling tube right?

I probably just need a longer tube which is no problem getting today at my gear oil supplier.

Thanks guys,

As jorton says, your transmission already has a pump. Just disconnect one cooler line, run the engine in Park long enough to pump out a quart, stop, refill, repeat, etc., ect. until the fluid is clean. Draining and refilling the sump first is smart.

Thanks Ken, in doing some reading in this section and going by what others state, the fact that I did drop the pan and change the transmission filter about 40,000 miles ago then the filter should be good for another 40K. I would like to see all transmission pans have a drain plug as does my Nissan X-trail, sure would be easier.

thanks again,
Cyprs

On a vehicle that I recently serviced for the in-laws, the cooler lines were somewhat difficult to access (to flush out the rest of the dirty fluid), so I found the rubber portion of one of the cooler lines, cut it and flushed it from there, then installed a Magnefine inline filter, noting the correct direction of flow. Now I have a convenient flush access port for next time too. Just another idea for folks to consider.
