I have a 94 chevy astro van...coming home one day the speedometer stopped working and the transmission would not go into 3rd gear and transmission fluid was leaking all under the van. We changed the speed sensor, filter, and gasket. It did not seem to fix the issue so we took it to have a mechanic look at it. He took off the speed sensor to check it and put it back stating that there was to much fluid in there and that the 3rd gear has gone out and that we needed to get a used one and replace it. We bought the used transmission and then drove it up to his shop today to be waitting on him on Monday. The transmission was shifting fine and the speedometer is also working properly. I need some advice on what to do...Go ahead and put the used transmission in or no? Does it sound like we fixed the issue? Please someone help with some advice.

You can definitely over-fill a transmission. If you had recently added fluid, I think this was your problem. Always check the transmission fluid when the engine is hot, and do not overfill.
The quick test to see if you're having a transmission problem is to look at a drop of the fluid taken from the dip-stick on a napkin. Look at the color and also for any sign of particles. A transmission that's going bad will grind up the gears and you'll see particles in the fluid, as well as the fluid sometimes having a cloudy, or burnt appearance.
Since you already have a replacement transmission, I would get it rebuilt (the gut's come as a kit of gears and this is what mechanics use to rebuild 'em) before having it installed. Like the other poster mentioned, you have no idea what condition its in, and you don't want to pay to have it installed only to find out its going too - especially since the astro vans are hard on their trannys.

The fact that you said he pulled the speed sensor out and said 3rd gear was no good makes me ill. By what you say, he did not inspect your transmission at all. Wanting to sell a used trans makes me more ill.
If as you say it is OK now, then do nothing. Other wise get it checked out the right way.
If you are in California, the law requires any shop to quote you tear down and inspect with the only parts being gaskets and fluids. Then have all parts he says must be replaced available for your inspection. Then a quote for the repair.
Do you know where that used trans has been? How many more miles do you want out of this van?

Id have to say that the problem may have been caused by the over filled tranny , as the fluid that was leaking may have got blown back as the van was driven and got into the speed se4nsor wiring and caused a faulty connection , if mechanic cleaned speed sensor before reinstalling it and you have proper fluid level now iwould not replace the transmission if it is shifting properly now as the used tranny you bought may not be in much better shape

If the tranny is not leaking and is shifting normally after replacing the sensor and filling the fluid to normal capacity, I would keep driving it. By the way, you should always check the fluide level of the tranny while the engine is running and at normal tempature) Too much fluid can cause the tranny to slip and lose fluid too. Some machanics just don't like to deal with small bucks, they'de much rather make a few more by saying you need to replace a more exspensive part..Hope I've helped...

Be careful, man. I had a motorcycle accident 2 months ago because a woman dropped her transmission fluid all over the road. 2 minutes later, another motorcycle got into an accident in the same spot. The cops easily found her car and gave her a big ticket.
The best thing to do is let the mechanic put in the used transmission. I've been there before...twice. Just pay him to put it in and go on with your life. It is expensive and there's no way around it. As long as your mechanic is local and not a national chain.
Beware of AAMCO and TUFFY'S because they have no shame talking to my brother the mechanic like a blonde ditz.

unfortunately used trannys could have the same problems,or worse.then you,d have to pay the labor twice,take the van back,take the time to drive it some.its your hard earned cash. but most trans when u removed pan a magnet in bottom should be clean and free of debris,if grey sludge in bottom of pan,these are the remains of one or more of your drive band clutches.trans is no good..check pan of used trans for these tips before wasting your money happy trails
