Transmission Flush

I've had some bad experiences apparently related to transmission flushes. Wondered if any one else has too.

In March 1993, had 1988 Buick Century wagon (165000 miles) tranny flushed. Had done it two or three times in past every 40000 or so. Tranny locked up in park after mechanic ran through grears one time. Cost of repair> 1700.00. I think some kind of pump failed. Not sure.

Last week, had 1993 Buick Cent. wagon (113000 miles) tranny flushed. Had done previouosly at 84000. This time, a couple days later, tranny wouldn't go into reverse or in any of the drive gears for a few minutes. Then, it started to work. HAven't had tranny looked at yet, so I don't know what's involved here.

Any one have similar problems related to flushes??

Welcome to the forum, I havn't had this type of problem before. But I recommend you have it looked at asap. It's important to repair a problem as soon as it happens because 9 times out of 10 when letting a problem go and not having it checked or repaired immediately, the problem gets worse and the cost to repair it usually goes up as well.

I would go back to the place that did the flush and explain the situation to them and see what they can do. You should have some kind of guarantee.


Autopro,

yes, I don't recommend transmission powerflushes in any car, they tend to send scrapnel through the transmission doing more harm than good. I also only recommend fluid to be changed if the old fluid is brown or smells burnt.

I checked. Mechanic claims 'first time ever happened'. No help. Have appt. tomorrow at tranny place. Lee Miles Tran.

Is there any solid documentaiton anywhere of this happening to people and their cars? I can't be only one. I think mechanic said it was a Wynn (sp) process/machine of some kind.

Threre's really no way to prove that the flush did the damage. It's logical to assume it could have, but you might just have shitty luck. And a older tranny failing at 165 000 miles isn't very good, but it's not that bad either.

I believe you, but do you have any 'proof'??

Sounds to me like the transmissions probably just failed due to age and mileage it just happened to coincide with your flush. It is a good idea to change your fluid at the recommended intervals, for one if you do not follow the maintenence schedule it will void any warranty, whether be factory or extended. Also once fluid is brown and burnt damage has already been done to the transmission.

Ive heard of that happening before, there are 2 filter kits that are almost identical, the same filter and the same tranny pan gasket, the only difference is the "O" ring that holds the filter in place. One ring is black and the other is red, the red ring is slightly smaller and causes the filter to come loose after a period of time. The service manuals at many shops have the filter numbers reversed so it is possible you have (or had) the wrong "O" ring in your tranny and it cause the filter to come loose. Its an easy fix if thats all it is.

Lol, my brothers 92 lincoln continental, 120K miles, gets a tranny flush, TRANNY EXPLODES ON THE HIGHWAY...

Fluid everywhere, all the gears in the tranny where eaten up.

From what i've been told, and know, from experiance is that if the car was maintained (tranny fluid flush every 25K miles) with the PROPER fluid. Make sure they dont use GM fluid on a Ford :-) Everything should be fine.

Now, just doing a pan drop, and drain is the most retarded thing i've ever heard. Thats like only replacing your oil filter, not the oil. They have to completely flush the trans, and the torque converter, EVERYTHING. Then replace the fluid.

BTW, i've seen this trend with mostly american cars, not to many japanese cars....hmmmm..

Yes, tranny repair shop touched on the same thing today when they called me. They are going to replace filter and see what happens.

This little article explains why newer cars would be perfectly fine to do a transmission flush. It's the older vehicles you don't wanna do it with.

Yes, thank you. Very interesting.
