Hello all, My 2009 JK Rubicon w/ auto transmission occasionally stalls out when coming to a stop. It can go a couple weeks running fine, then do it again, sometimes two or three times in a row, then run fine for another period of time before doing it again, No codes thrown. Have replaced airfilter, plugs, wires, coil, camshaft position sensor, tried HEET in the tank for any possible water in the tank, no engine mods, all stock. We fuel at the same station 90% percent of the time as with our other vehicles that run fine with the same fuel. Sometimes when it stalls, it will start right up, other times very difficult to start... any ideas would be greatly appreciated. Thanks, Russ

 

Not that experienced with auto transmissions, but it may be that the torque convertor lockup isn't fully releasing on command. Might try changing the trans fluid and filter. Suggest using synthetic oil in the trans. There are no DTC's to help troubleshoot, correct? Another thought that comes to mind is cleaning the throttle body if it's gunked up.

 

Mr. T, Thanks for the reply, I'll look in to the trans/torque converter possibly being the problem. I hadn't thought of that. I have cleaned out the throttle body and correct, no DTC's being thrown. I'll keep plugging along with any ideas. Thanks, Russ
