Hello everyone, I have a 99 Dodge Dakota SLT 3.9 V6 auto, I started having problems with it stalling and having issues starting again. The garage that worked on it said it needed a new computer, or so they thought. I didnt agree but it got one. The next day it had problems again, when in reverse and in idle the RPMs would jump up and down and want to stall so instead of taking it back i tried to fix the problem myself. I replaced the idle air control valve and thought the problem was fixed.

After a 30 minute drive i started having RPM problems again, it would have problems shifting out of 1st and 2nd and 3rd and would hard shift. I replaced the Throttle Position Sensor. Again I didnt have any problems, until after 30 mins of driving, then the same problems again.

So what next? Is it my transmission? Why is everything fine until after the engine gets warmed up? Could it be the torque converter? Any ideas? Any help would be greatly appreciated!

 

throwin any codes?? did ya try clickin key back and forth 3times to try and get codes when it happens, sounds like a tranny sensor. dont remember but does your truck have a map sensor??

 

I didn't try the codes thing, I didn't know about that. I believe it does have a map sensor but haven't tried that one.

 

I tried the key thing, it didn't give me any codes.

 

Yeah my auto 3.9 will occasionally stall in the driveway, though usually only if I move the selector between drive and park slowly.
