As others have posted, its probably fuel. If fuel delivery is not the problem, one of the next (a part from a sensor) would be if the torque converter is locking up at low speed. I have had it happen a couple of times when the engine/trans is cold. Try dropping it into neutral as you slow to a stop & see if it still stalls.
Thanks for the reply. I have been dropping it into neutral as I come to a stop and then it keeps on running. Is this normal for this type of car or is there a solution to not having to do this? Does become quite a problem in heavy traffic.
It sounds like you're experiencing a common problem with these transmissions. I have this too, but like layback40, only occasionally after startup on cool mornings. It feels like forgetting to hit the clutch at a stop in a manual transmission. Kind of a violent wrestling mach with that little beasty under the hood. Your variety sounds more frequent and maybe less violent?
There has been plenty of discussion of this on lost. Just use google and search "transmission drain back site:www.lostjeeps.com". Easy things to do first are check trans fluid level and make sure it is filled with the right stuff. The marks on the trans dipstcks are wrong, so it should be well over 'full' and you should see clean atf+4 fluid. If you do a fluid change, there are some parts that should be replaced while the pan is off. Maybe someone with experience doing that will chime in here.
Drainback issues results in slip\no gear engagement\vehicle won't move until pump picks up enough fluid to build up hydraulic pressure in the apply circuits when first starting the vehicle after it sets overnight or for several hours.
The engine stalling immediately after startup and driving it a few hundred feet and trying to come to a stop with the vehicle is a common problem with worn parts in the front pump assembly of the transmission.
The original oil pump housing in the transmission was failure prone resulting in low transmission oil pressure which led to torque converter problems and shifting issues.
Severe wear of the TC limit valve bore in the front pump housing results in loss of
converter release oil pressure. Reduced release pressure at low speed and idle can drag the converter linings, causing engine surge, pulsation or even engine stall.
Best to replace the front pump assembly anytime you have the transmission out for any other reason if it has never been replaced. Most also add a TransGo Kit at the same time.
