Draining Tranny Oil for Trans-X Question

I want to drain a bit of my tranny oil to accommodate a can of Trans-X..... I was thinking that the easiest way would be to drain it from one of the oil cooler lines at the bottom of the radiator. Any thoughts on this? Is there another spot where theres a drain plug to unscrew?

Yes.. there's a drain plug in the tranny pan. Needs a 5mm hex bit iirc and might be in a little on the tight side, so you'll probably want a socket-mounted hex key rather than an "L" shaped hex wrench. Just don't drain the whole tranny

tobybul.....easier way would be to just pi-pette it out of the dipstick down tube with a clear plastic length of tubing that you can buy at any hardware store in the right diameter. It might take some time but it will be much neater and more precise that pulling the plug on the pan or pulling a cooler line......sometimes those coolers lines do not reseat properly after untightening and retightening them and then you have more of a problem....
Buy about 48" or more so you can apply some suction but still see the level in the tube and avoid getting a mouth full. Then dump each tube full into a container that is marked for a 1 quart volume which I believe is the volume of the Trans-X container.
Ideally you would want to use a fluid evacuator like an Evacuator Plus to remove or adjust any automotive fluids....well worth the investment!

If you have a mity-vac use that to measure what you remove, I did that when I over filled.

imo

imo, pulling the transmission oil cooler lines will only spill a little fluid out.

If you don't have the vacuum, what I did on mine was spill out enough from the drain plug at the bottom of the transmission pan, then quickly plug it back up.

just be carefull after you put in the trans x, to make sure your level is correct...

I just undo the drain plug. I don't want to deny it it's purpose.


patbob, why do you say not to drain the whole tranny?

pump from a liquid soap dispenser

And a length of plastic tube from the hardware store. I cleaned it and pumped some tranny fluid from a bottle through it first. Works fine if your not going to reuse the fluid. I pumped into a clear quart bottle to monitor how much I was removing.

Brilliant idea! Never would have thought to use a pump off a soap dispenser.......

Trans-X is a band-aid for a problem that needs to be fixed. There are so many adjustments on the tranny that there is almost no problem that cannot be fixed through correct tuning and adjustment.

Maybe it's a band-aid, but I was having problems with the tranny on my 300SDL and put Trans-X in. The problem went away and hasn't returned in about 40,000 miles of driving since. The mechanic was talking about a tranny rebuild, so I figured I'd try it just to see. I was very happy with the product.

Clear tube down the filler tube with mity vac would be how I would do it. Easy to measure how much you're taking out, its easy, and clean.

Because he's only looking to drain out a quart or so so he can add Trans-X without overfilling it. Be far too easy to drain out a lot more form that plug.
