Technican: When it initially stalls, is it while you are coming to a stop or slowing down?
Owner: coming to a stop.
Technican: The TCC (torque converter clutch) solenoid is sticking. This causes the engine to stall while coming to a stop, the same as if you tried to stop with a manual transmission without depressing the clutch.
Owner: where can i located the tcc? can this problem be due to bad gas?
Technican: It's behind the side cover on the transmission. You'll see the electrical connector for the tcc on the side cover.
This problem happened so much there is no reason to think it was caused by bad gas.
If you give me an email address I'll send you a link that describes the repair.
Owner:
Technican: Check your email.
Technican: Don't check your email... for some reason the email was returned. Here is the email (simply highlight, copy, and paste the links into your address bar).
Here are a couple of links for replacement of the tcc solenoid. Use them as
a general guide, some are actually easier than these instructions show. It
all depends on room to access the side cover.

Here is another link that describes replacement.
Some people disconnect the tcc electrical connector at the transmission to
cure the problem. This will prevent the car from stalling again. The bad
news is the engine light will turn on, fuel economy will decrease slightly,
and the transmission temperature will rise. This probably sounds worse than
it is, but I wanted to let you know there is a quick fix but it is not
recommended as a permanent fix. It's your van and your choice. Here's How To Get Guaranteed Solutions In Minutes
