I have a 2000 Durango 5.9L with a Check Engine Light on. I did the key turn on off on off on thing and get the code P1740 on my odometer. I checked my Chilton guide and it doesn't list a P1740 Code under the OBD II codes. It says that I need to use a DRB II tool to get the codes, but I think I have it already. Does anyone know what this code means?</P>


I've posted this in the Durango section as well, but I thought it might be the same for all the Dodges. Thanks for any help you can provide. </P>

yep got ya covered dude</P>


p1740 is the tcc or o/d solonoid performance</P>


set conditions are when the dtc will set if the expected engine rpm to output shaft speed rpm ratio is not acheived during tcc and/or o/d engagement. this indicates malfunctioning tourqe converter or overdrive clutch.</P>


possible causes are tourqe converter/internal trans prob-o/d clutch/selas or valve body contamination/oil burnt or oil panhas excessive debris/cooler flow restricted oil pump or shaft/trans fluid inter gov pressure sensor signal/inter tcc solonoid</P>


well hope it helped ya</P>


good luck</P>

 

Thanks alot for the information. I was really hoping it would be something CHEAP, but it sounds like one I'm going to have to get looked it.

 

What did you end up doing about this problem?
I am getting the same code on my 2001 Ram 1500.
thanks

P1740 usually means the torque converter and input shaft need to be replaced/resealed.
