I changed my transmission fluid about 10 days ago, couldn't seem to get an accurate reading on it until I was on my way back to Memphis. I then realized that it was about two centimeters over the top line. I'm guessing that this is probably only a quart or two over, so I don't want to drain my fluid again. I don't have good space to do that. I was wondering if I could hook a hand vaccuum pump up to a piece of fuel line and draw up a couple quarts of fluid from the dipstick hole.

You're probably only a cup over. Beyond the top mark very little goes a long way. But it's a cup that'll cause big problems so get it out of there.

Don't hook a hand pump directly to fluid or you'll make a mess of your pump. Have the pump evacuate a sealed bottle and run another line from the bottle to the dipstick tube. That's basically the brake bleed attachment for a MityVac.

I would put a clean catch pan under the trans fluid pan and crack open the drain plug a little at a time untill fluid just starts to come out. Drain off a quart or so. Then you can add back what you need.

I used the Mity Vac.

In the middle of the tubing I hooked up the canister supplied with the pump, just as Sixto described. I had the car idling and checked the fluid level and then put the tubing down into the fill tube while constantly squeezing the handle of the vac pump until the needle started to move and show vacuum. I sucked out fluid filling up the canister and then re-checked the trans level. It was right where it needed to be.

No mess and it was easy. Just the way I like it

+1 for MityVac with reservoir attachment. Why make a mess or drain more than you have to?

Here is what I use.

I also evacuate the crankcase and power steering reservoirs of my cars with this.

Replace your transmission cooler hoses. You will probably spill just about the right amount of fluid and get new hoses at the same time. It's a win-win situation all the way around!!!

I agree with tangofox. Even if you have new hoses, just disconnect one for a few seconds and reconnect. Badda bime, badda bam, badda boom!

The problem with the evac system is that all the crud in the oil rests at the bottom of the pan; even if it is hot, some crud will always settle at the bottom. This is why the drain plug is located there. Also, a high pressure evac just might pop out a seal.

I'd like to chat with you guys more, but I really belong in the 4-door section.

These extractors use vacuum, not pressure. Leave the oil filler cap off and there won't be much vacuum above the top level of oil as it drains.

Ditto, I've done it, no prob.
