Draining Tranmsission Fluid, 2001 SAN GT40

[vr6mole]

Service manual explains how to drain engine oil and v-drive oil but no mention of how to drain trans fluid, only how to check the level.

I looked around for a drain plug and was unable to find one.

Is the only way to use a vacuum pump and suck the oil out?

The pump is the only way I know to do it.

The pump is BY far the easiest way to do it.

And make one of these so you don't lose any pieces into the tranny or get your tool stuck in the hole. There are at least two posts last year with some "lessons learned".

Attach the hose to your pump and stick the copper tubing down into the tranny. There is a larger hole in the case for the dipstick rubber stopper and then a 3/8" or so hole machined in for the dipstick. You will need to stick the copper tubing in there several inches to get to the bottom. Hose clamp the pvc hose to the copper so it doesn't leak or fall into the tranny.

Changing the oil

The other thing to remember is to measure the amount of oil you remove from the transmission so you can replace with the same amount. After I use the "suck out" I pour the old oil into a measuring device and measure the amount. I then use the same measuring device cleaned out with fresh oil to replace what I removed. At least this way you are close to having it full so you do not damage your v-drive or transmission.

Good point and there are several threads on tranny fluid changes he should search for and read. One thing to note is that transmission fluid expands greatly with temperature. I've changed my fluid several times and always after a strong workout. I suck out 2 1/4 quarts but I only put back 2 new quarts. After I run it and check the level, it is right where I was before the change.

I'm sure however each person does it, they ensure the level is correct when they're all done.

thanks for the help everyone.
Airtool- I searched around and could only find what type of fluid to use and the capacity. Not anything about actually doing it.
