Thread: Changing fluid, geting it all out

I want to change my transmission fluid this weekend along with installing my shift kit but I'd like to get as much of the old fluid out as possible. I've read a few different ways of doing this. Anyone know a good way to do this? I read about putting a tube down the dip stick and sphining it out but heard it could take over night to get it all out then. Which I don't mind, I'll start friday night if need be.

youll never get it ALL out, unless you drop the trans.

Id just do the filter gasket when you do your shift kit then get it flushed, or do the fliter/gasket/fluid then the shift kit, this way the filter and fluid are all new, get a new filter and 6 qts of fluid( maybe less) and youll be set. I found this way to ensure a near complete fluid change.


How many miles are on the car/trans?

73,000 on it. I was planning on just dropping the pan then doing the shift kit, then put the filter on and put the pan back on with a new gasket then filling it back up with dexron 6

IF you want to get creative and do it yourself you can start up the car with the feed cooler line unhooked from the radiator and sitting in a large drain pan- there is about 20-40 psi here so make sure the line is support and it will drain fast! IMMEDIATELY after you see the fluid quit coming out shut the engine off and dump 6 quarts back into the trans and do it again. Repeat this until the fluid looks like new coming out of the tube. Generally flushing a trans takes about 12-25 quarts depending on how bad the fluid looks and if it looks bad to start with then a complete flush is not the best thing to do, there is info on my website info page of why.

Thanks a lot, I'll give that a try. I'd rather not spend money on new fluid then go out and pay $180 for a full flush. I'll let you know how it goes.

Im not sure what these tranny's take, didnt figure their pan capacity was bigger then a rwd th unit.

I get to do it on the lawn so I'll have to find a way of covering all of it so no animals get at it. I'll let you all know how it goes.

I made a 3'x3' box a long time ago, had about 100 pounds of cat **** litter in it w/ a fine mesh reinforced screen about 1" down from the top of the box, saved so much time cleaning and no missing or "lost" bolts in the drain pan. Also, tranny fluid is not harmful in moderation to humans or animals( makes em wet **** alot) however its the anti-freeze and mainly the green kind thats toxic, im not sure on the dex-cruel ****.

yeah but my dogs a retard, he'd eat it all up.

alright, another question. I don't want to start a new tread as its kind of along the lines....sort of. I got a shift kit. I'm just trying to figure out exactly how much of shim I should install for my shifts. I have (1) 1/4", (1) 1/2", (3) 3.4" and (1) 1". they recommend the 1/2 on the 1-2 shift, and 3/4 on the 3-4 shift. I want something that I'm going to notice a difference in shifts. I don't want it to seem like its just quicker. I don't need tire chirping as I figure that will hurt the trans but it would be nice.

well did it sunday, went great. Shift kit works fine. Not as much as a difference as I would have thought but I think with a new PCM and the raised shift line pressure that it will be rather nice. Shifts are much firmer though and it feels an overall smoother.
