Flush - outside pump pushes fluid throughout trans and out through cooler lines. Dont' necessarily use detergents or chemicals. Essentially two pumps are running at the same time. May put pressure where it isn't normally.

Exchange - uses transmission pump (the one that provides fluid pressure for operation) to push fluid out of cooler lines.

Drain and fill - pull trans drain plug and drain fluid out of pan (approx 3.5-4 qts) and refill.

Example of why seals don't like to do anything than be normal. It is a brake system buy none the less same principal. RX's suck the fluid out of each caliper using a vacula (air operated vacuum device for exchanging brake fluid) Almost guaranteed to blow (suck) the seal at the end of the master cyl, usually requires replacement of master cyl and brake booster (full of brake fluid). Same method but rather than powering up the vacula just use it as a catch basin and pump the brake pedal while opening and closing the bleeder valve - normal bleeding procedure. Seals stay intact and nothing is damaged.

My son reports numerous cases of BG-flushed vehicles with over 300K miles and original trannies...

My Taco is running strong after same a couple years ago.

I've never been disappointed with BG products.

Well my argument against has always been not wanting to dislodge any little particle that was sitting in a happy little corner somewhere. I never considered the seals, but this won't be the last time I learn something from LexiBen now is it..


But you know about 4 qts drain out when the stuff stops dripping out of the pan. If you raise the right-front it will be a little more, also if you wait a while (like hours) it will be a little more... the rest of your ATF stays up in the torque converter.

Then to fill you just shove a funnel in the dipstick hole, and slowly add back the ATF. I usually stop at around 3.5 qts to check it but end up right at 4. My brother's 4Runner takes 4.5.. and I do this at every oil change. To get really geeky, Raven created a spreadsheet that predicts what % of ATF is new with every 4 quart swap, I'm sure you can find it if you look. Easier, IMO, to just start fresh, then keep it fresh. At only 2 OCI's per year I think the added cost is well worth it.

Excellent. It is real world experience like this you don't find in the FSM or owner's manual . I've seen that spreadsheet as well and also agree it is easier to start with all new, expecially on a rig with pretty much zero known history.

I did the fluid exchange on the tranny at Toy Car care for $99. The flush is not not good for 80 trannies.

Hmmm. Didn't know 80 trannies were weak. Wouldn't have expected it.

Time is the issue for sure...Both 's doing the soccer thing, wife going out of town, ...

And I'm slow...Not mentally, I just tend to get really anal about the work which slows the process. Ask the wife how long it takes me just to hang a picture . Get out the tape measure, hammer, nails, level, pencil, etc. etc., get it all measured out and lined up, measure a few more times

I want to spend what little time I have getting what mods I can afford installed and ready. I imagine the oil change and diffs are pull the plugs, drain, put plugs back in, refill. Easy but then you have to fartz around with getting rid of the oil...The AT fluid exchange is more involved from what I read but doable.

Realistically though it is hard for me to find a solid hour to work on stuff right now let alone a full day . Based on Tim's estimate of the fluids cost it doesn't seem like the Toy Doctor is making much on the deal so maybe there is a 'catch'...Need to call them and make sure it isn't one of those deals where the coupon applies to "most vehicles" but not mine type of thing.

Is this the place on Parker? If it is, or is connected in any way, do not even think about using them.
