If your speaking about Chryslers 41TE elec. Cont. Transaxle, it came out in late 88 and by 1989 was in many cars and minivans. Although many original units had no complaints and were successful, others were not. Internal changes were to a piston and seal which got stuck at times and delayed movement causing a tough downshift to 1st gear. Called a 'bump stop'. Other changes were made internally but not many and none expensive to any cust except the original 100.00 deductable. After those changes took effect, it was mostly software updates and control module replacements. I did not see too many vehicles that didn't have trans problems (because of my occupation) but they were in great numbers. Even if they were not serviced per the owners manual recommendations. Since 1990 95% of the changes were software. The trans was different, and some customers never liked the way it acted and some did. After an update and overhaul any cooling problems had to be addressed or it would fail again. If I had to chose a Chrysler product, it would have been a 3.3L, 41TE, fully everything minivan. There was no better running or shifting vehicle for the money. It was very safe because of visibility while at the same time did not hamper other vehicles visibility. Many customers chose to use their selling dealer or any other Chrysler dealer exclusively, and are still doing it today but most problems came because of cheaper, less, and unrecorded maintenance. I mean anyone who charges 34.95 for a trans service has not the time or the quality of parts to match the units performance and any little differences in small seemingly impossible small parts or time of inspection led to early failure. Of course I just was a Chrysler transmission technician and am only looking at it from that point of view. It wasn't a transaxle designed for many different drivers in one van though because of its software characteristics. If it was real bad, it would have been gone way before 1994. I think 1995 was the last great year for the S-body. After that it was a different design. CAD designed. Thanks for reading.
