I wouldnt waste your time. I would go right away and have your tranny fluid flushed and changed.

You dont wanna screw up your transmission.

do i need to do a full flush with only 50,000 miles on the car

Its recommended but you dont have to. If the trans has over 100,000 miles on it and its never been done, I wouldnt even touch the fluid. Chances are that's what's holding it together.

This is very true. I used to rebuild trannys. New oil will clean out all the sludge and varnish, and then it will start leaking oil.

We use the BG chemicals and flush at my shop, with the machines. But we won't do one that has a whole lot of miles on the oil.

In these cases, I'd just do it the old fashion way, and change the filter, and reload with oil. You'll only be changing 2.5 qts that way.

so its not good to change the oil of the tranny if its been 100k miles well my car has about 109798miles on it and i dont know if the original owner ever changed it so the best for me is to just change filter and reload on oil..

my car runs fine now and the temperature is in the 30s to 40s. i think it didn't shift right because it was so cold. some days it got to 30 below zero. i'll just do a drain and fill and see what happens

Staceman · 02-23-2007, 04:51 PM

Reason I asked was was that when my tranny is cold in the AM, it takes a while to warm up, then finally shift correctly. However, now it intermittantly just disengages all together. RPM's go flying up with no tranny response. Pulling the car over and shutting it down for a few minutes takes care of this. I'm gonna pull the codes off the tranny later and hope for the best. I am guessing that I have a fouled 2nd or OD shift solenoid. 133K miles. I've drained and re-filled 2 qt. method 4 times, and cleaned the filter screen. Hardly any shavings on the magnets. Just a little bit of fine gray metal dust.
Anyone near Phoenix got a good auto tranny??

wait...so if the transmission has never been flushed for over 100k miles, you just dont change the oil? well that sucks haha. what should you do instead, if you cant change the transmission oil, to make sure the transmission will run as well as it can?

Staceman · 02-23-2007, 10:09 PM

Well, checked error codes. Nothing but a single blinking O/D Off light. I noticed my battery connections are all corroded over. I'm gonna clean those up real good this week-end. Will it help? Don't know. But it aint gonna hurt. Wish me luck!

I'd like to know, too. I've been having really hard shifting when I try to get up to 55 mph fast to get onto the highway. I gotta slam the gas and then let up quickly to make it shift. It's been going on since I got the car running again...
