Does anyone ever do this? Is it hard? the shop wanna charge 90 bucks for this job. They said that will be a lot harder than changing engine oil and required a special machine to do the job.

 

Remember that if you go to special shop they will do it with a special machine..that can such all the old fluid from the tranny and clear all s.......t so you can see if you can do this job by yourself

 

Draining the pan will usually yield 4 litres, the whole system is 10 litres. If you want to drain and flush the whole thing I posted this earlier on another thread when I installed a transmission cooler. Drain the pan first, replace plug and refill with 4 litres or the amount you drained out. Do not start the engine. You need to disconnect the hose from the transmission to the radiator.
I used a 1 gallon clear windshield washer jug, put the end of the transmission hose in the jug and get someone to start the car and then yell when you want them to stop, it comes out fairly quickly but not enough to force the fluid out the jug top, but make sure you hold on to the hose and the bottle to keep it steady. It takes about 15 or 20 seconds to get half a jug which is what I did and then refilled and did another half a jug till it came clear. It took 10 litres for me. I have read that some people did it in 1 gallon increments and others 1/2 so I did the half.
I did a cooler install at the same time so I had a long enough hose on the output from the transmission to easily run to the jug but the stock hose is short so might be advisable to put a longer one on or attach an extension to it.
Also just put back in the same amount you take out and then run it a while after you are all finished. I found that the stick showed low at first but came back after a short drive so I was glad I didn't add the extra litre I had purchased.

 

It's easy to do on your own. Follow Jime's instructions.

 

Do ao search in the last 6 months with Jime's username. You will get tons of hits. I did the drain-and-fill technique twice (still doing it one more time) and I think tha tthe tranny shifts a LOT better, plus it is still getting 90% of the fluid changed if you do the drain and fill 3 times.

If you just do a drain and fill, it is really easy- just like an oil change.
