torque converter

hey, I'm new here. My wife has a 1998 jeep cherokee and I just found out that the torque converter is sticking when the car is running hot. the thing already stalled on her as she sat in traffic going into the lincoln tunnel.

does anyone know how involved and expensive it is to get fixed?

Personally, I'd install a tranny-cooler first, as it will be handy in a long run...
and seeing that your problem occurs from heat

Repair wise... I don't much info to tell you, but I know fixing a tranny is a lot of work, knowledge and of course.. $$$
Look for a AW4 in a junkyard

I don't really know too much about it myself. I dropped it off at the shop and the guy called me this morning and told me about the torque converter. I realize getting a tranny fixed is no walk in the park.

all I know is that the thing runs fine most of the time. I don't get worried driving it around town, but now that I know about this torque converter problem, I'd be a little scared to take it too far.

that time outside the lincoln tunnel is the first time it stalled. would the transmission fluid have anything to do with it?

the AW4 is a very finicky transmission, it could just be asking for a new filter and some new blood. It could also be on its way to leaving you stranded. Start with a good signature so we can see what your heep has going for it. Then move on to a tranny cooler. A nice ice cold beer should be third on your list.

The torque converter is part of the transmission, but it is simple to replace. It just pulls right off and you slip on the new one. You will need to remove the transmission to install a new torque converter.

Get the transmission serviced with a 100% fluid change and new filter and have a tranny cololer installed. Then see if it has more trouble before you just throw big money at it.

AW4 is a tough tranny... IMO it's very unlikely that it'd just fail like that w/o abuse

if the engine overheated the you likely burnt up the fins in the TC...it's not unlikely. especially if it was hot, not overheated per se, but hotter than normal for an extended period of time. the tranny cooler is in the radiator...so if one's hot so is the other.

i'd try just replacing the TC and put new fluid/filter in. if you still have problems, buy a yard tranny, or have yours rebuilt using the new TC.

check the fluid for a nasty smell and a dark color. also look in the filter (if you can) for metal shavings and dark spots. also check the level of fluid on the dipstick.
