Tranny Service Flush

I have killed two trannies on 88 (167000) and 93 (113000) Cents. due to tranny flushes in last 21 months. First couldn't get out of park while still in garage and second died (slippage) two days later AFTER flush. Mechanics all said I was on something to think that a flush would kill a trans. Both cars got first flushes later in life of trans. Hve had real good luck getting 96 Explorer tranny flushed without probs. This was done first at 21000 on the Ford.

Any thoughts????????????

I have heard nothing but bad things about transmission flushes. Most transmissions die within a couple of weeks after one has been flushed. If you change the fluid and filter like the owners manual says you should never need to have a transmission flush. Besides, what are they supposed to be flushing out when they do one of these? The only thing I can think of is the money from your wallet.

Agree....how do they get away with this??????? This is real money when a tranny fails!! The machine used on my car was a Wynn Trans-Serve II - Plus. I'm going to call Wynn next week and see what happens (not much).

Ditto, I had my Lesabre flushed and in less than 10K it went south. There is a nipple they attach a hose to inside after the pan is removed. They cracked the nipple and it broke causing insufficient fluid to circulate.

I have had most of my transmissions flushed, including 1992 Century, 113k miles. No problems whatsoever. The place I go is rather competent. They don’t remove the pan, they hook up where the trans. fluid goes into the radiator. I recommend a pan service (just fluid and filter) over a flush if the trans hasn’t been serviced much. The filter must be clean. For slippage add Lucas stop slip. For rough shifting use LubeGard AT protectant. Use the best AT fluid you can afford and keep the fluid level right on the mark if possible. Check fluid while hot, idling in park.

I just bought a 96 Toyota. It has a ATF drain plug so you don't have to drop the pan to change ATF. I probably won't senpd the money for a flush on it.

okay really, you may want to monitor your maintence of your cent a lil more, just because you are having a few unanswered problems in your daily driving doesn't neccesarily mean that a flush is the best answer. I don't know who is telling you that it is a good one (probably the people that are fixing it) but if you must do all that you can to be nuetral first.

Next time you change your oil check your tranny gasket. If they are dirty or oily then it may be time to take $12 and some change over to autozone and grab a new gasket. Changing your gasket will keep your tranny from leaking fluid and stripping gears. It really doesn't matter how or when you flush the car if your leaking that regardless. Another thing to check is the fluid itself. When you change your transmission fluid then you must keep what you have to measure how much you need to put back in there. I'll post again if you need further help.

P.S. Just in case someone wants to come behind me Autozone sells the filter with the gasket so obviously you don't forget that.

Geeze... This thread has me wondering. I have 176,000 km on my 2000 Century, and have never had the Tranny serviced in any way. The car runs fantastic, getting 26 - 29 mpg on average, even in this weather, and have no noticable problems at all with the transmission.
I have scheduled a flush and filter and fill in two weeks, just because I think I have to, but now, I don't know if I should. I had our Explorer done at 169,000km, and it is now 225,000 with no problems, but that manual states if over 170,000km without a flush, don't ever do it unless it leaks.
Should I keep the apointment or cancel and leave well enough alone?

Do a pan service, not a flush. Drop the pan, change the filter, clean the pan, change the gasket........

I whole heartedly agree with Rum Runner. A Tranny Flush has two inherant problems. One, you can't change the tranny filter. Two, you can't look for shavings that might be attached to the magnet on the pan. The very same shavings that might get pushed back into the tranny with a flush.

Take the time and jmack up the car and service it like your Grandfather (or at least mine) would.

My two tips for changing tranny fluid, I use a cheap plastic hand pump, connected to a thin plastic hose inserted in the transaxle fluid check tube, to pump out most of the fluid before I drop the pan. Then I leave the pan off overnight, it's surprising how long it keeps dripping, and the more of the old fluid removed the better.
I'd suggest changing the fluid, it takes alot of wear, can't expect it to last forever.
