Rpm drop

[SILVER_BULLET]

So I'm almost sure it's my converter but just making sure. In second gear while I'm under part throttle I get a small rpm drop like 100-200 is that the converter or another issue

sounds like converter locking up....which is normal.

locking up that early though this happens anywhere from like 20-45 mph and it kinda does a little jerk sort of thing

That sounds kinda wierd, have youu asked the manufacturer if that's normal? I don't know a ton of guys on here that have aftermarket converters.

 

[Graygoose]

Is it stock converter?

 

[SILVER_BULLET]

its not aftermarket its still the stock rt converter im making sure thats the problemd before i order my edge converter

 

[Graygoose]

thats sure what it sounds like...

This isn't the MDS kicking in & out? Dodge partally unlocks the torque converter when the hemi goes into MDS mode to reduce the feel of the vibration in four-cylinder mode, so a slight 100-200 rpm increase is seen on the tach, then it dips back down when the TC locks in eight-cylinder mode. I haven't tested keeping it in second gear to see if it still happens but just thought I'd mention....

Nope not mds because it will do it when i have it in second with the console shifter also....the only time it does not do it is if i give it more then half throttle or if i have it in tow haul mode. I would actually drive it all the time in tow haul if it would have just a little bit lower upshift into 4th gear

It is possible that you have a pump problem. Tow/haul boost line pressure and changes shift points

Could also be a solenoid pack on the valve body. I have seen a few of those.

I guess it'll have to go to the dealer

Here's a video of what it does it's kinda crappy because it's from my phone but you can see when it's in second gear it drops the rpm a little at around 2000 rpm
