My transmission stopped working March. The van sat for 2 months while I searched and purchased a used transmission to be installed. I got it back 2 weeks ago and it shifted a little hard and after removing the battery terminals, cleaning and letting the computer reset, it was operating very well, though it still had some jerking going on. I assumed this was from the gas it had in it. It had almost a full tank of gas just sitting in it for the 2 months it was down. I used some MAF spray in the mass airflow sensor to see if this would help. It was better, but didn’t go away. After a few days, it stopped shifting again. I found out we didn’t leave the battery disconnected long enough to completely reset the computer, so we performed that step again. The van shifted fine for almost a week and today on the way home from work, I stopped to get some gas treatment since I will be filling it up tomorrow with fresh gas. When I left the store, it stopped shifting. It got up to over 3000 rpms at 40 mph. I babied it home which was about 2 miles away. I am at a loss now. Am I going to have to keep resetting the computer? Since my brother in law is the one who installed the transmission, do I need to break down and get it to the transmission shop? I am getting so frustrated with this van. I just want my van to operate correctly again.
Need a replacement transmission? Quality transmissions are hard to find.

In this case, though, it is obvious that there is something going on so you need a place to start looking. In this case, it might be a good idea to look at the differential.
You indicated that you found a replacement transmission and, assuming you just had it swapped in, and had things buttoned up again — after performing the various steps you have to take — and, with that all done, you turned the key, it may very well be that the splined end of the transmission output shaft and the existing differential are just not meshing.
It is very possible that when you pulled out the first transmission that the relationship that existed between the former transmission and your van’s differential ended and that any new transmission might just not work, in the long run, with the existing differential.
No, this isn’t the way it is supposed to work as “interchangeable parts” are supposed to be “interchangeable,” meaning that every part is supposed to work with other parts, no matter when or where they are put together. However, the truth of the matter is that many times parts “learn” to live with other parts in a vehicle (it’s like a marriage, you learn to live together) so that everyone is just happy working with the part it has had working with it for some years.
When you break up the relationships that existed then vans and things tend to be unhappy and then they don’t work correctly.
With that said, look at the differential and be sure that the driveshaft and half-shafts are also true. If they are slipping out and not working then your van won’t run correctly no matter how many transmissions you drop in.
