How to prevent the transmission from damage
(The filter usually is screen type and can be cleaned when remove bottom cover. but this is not to be done at regular maintenance inspection.)
- Regularly check your parking space for leaks. Doesn't matter, is it the engine oil leak, power steering fluid or transmission fluid; if you discover any, get it fixed before it caused something serious.
- Once in a while check the transmission fluid level and condition. Not all cars however have the automatic transmission dipstick, in some cars, for example, in late Volkswagen models, the transmission fluid can only be checked by the dealer. Consult with your owner's manual for details. If the transmission fluid level is too low, there is a leak somewhere that needs to be fixed.
- Change the fluid as often as it said in your owner's manual or when it becomes too dark (rather brown than red) or dirty.
Also, keep in mind that an automatic transmission can not be drained completely - there is always some transmission fluid left inside the transmission (the torque converter, in the valve body, etc.) which means you only can change about %60 of the fluid at once. This is one more reason to change it more often.

- Use only the same type of the transmission fluid as specified in the owner's manual or on the dipstick. Some vehicles (e.g Dodge Caravan) are very sensitive to fluid type
- Never shift to the Reverse or Parking until the car comes to a complete stop.
- Never shift from the Parking mode when engine rpm is higher than normal idle.
- Always hold a brakes down when shifting from Parking.
- The automatic transmission can be damaged if towing with the drive wheels on the road. Always use a dolly or place powered wheels on the towing platform (if the vehicle is front wheel drive - tow it from the front leaving rear wheels on the road.

there is a pan at the bottom of the transmission that you can drain the fluid from.... you'll need to get a new gasket and it's a good idea to change the filter at the same time. usually you can buy that in a kit that includes both... most automatics don't have a drain hole. but be aware that you have to make sure that that is the correct transmission fluid for the tranny.
also realize that draining the pan and changing the filter is good maintenance but there is still a large amount of flud in the torque converter and transmission cooler.

I'm not sure how advisable it would be to mix the two types of fluid

changing the filter might be a better option... also when you do that there is a small magnet in the pan ... it catches any small metalic flakes as the bands wear.
and while you have the pan off you can adjust the bands... you'll need a manual to make suire that is done properly... that is if that transmission requires adjustment.... as far as i know the new electronic transmissions don't need to be adjusted.

I am confused - I have a simple query and logged on to your site as you offered free advice! Do you not offer the service as described on your website. I definitely don't need a team of experts to answer my very simple question.

There will be a plug on the bottom of the transmission casing to let the old gearbox oil out.
On an automatic trans the filler is usually on top at the trans dipstick.
On a manuel trans there is a plug about half way up the trans casing.
Drain fully and put in correct type and amount according to your manual. Do not put any old trans fluid in use the type and quantity recommended by the manufacturer!
I find myself just going to a Quick Lube Shop and letting them do it for a few bucks more.. They get it right and it's faster than me doing it myself.

Hope this will FixYa!
