I drive a 2011 Jeep wrangler Sahara unlimited. Recently replaced all 4 wheel speed Sensors, the transmission fluid and filter. Still having some issues with the transmission, I think, after driving for long periods of time. Its not a grinding noise. Doesnt feel like its slipping but there is a slight shudder. The only way i can describe it is it sounds like and feels like a belt letting go of something then catching again. Had a P0731 (gear ration error in first) and P0732 (gear 2 shift incorrect ratio) up until I replaced the sensors. I have a video of the noise it's making but it won't let me upload it. Any help or suggestions would be greatly appreciated.

 

Ropesville.....now there is one I had to look up! I think you really need a scanner that can read your actual transmission module codes and they might shed more light. Something like the Jscan app and a BT dongle off Amazon is an invaluable tool for a small bit of money. I'd think maybe going to be torque converter related. for videos, it's really best to just upload to YouTube, then paste a link to the video here and it will embed in your post.

 

Yeah Small town. Mos times I have to say small town south of Lubbock then people somewhat know where it is. Thanks for the info will try that and see what I get.

 

This is the video I mentioned.

 

I am with Resharp and say TC isues - slipping and grabbing TC clutch perhaps. Trouble is all that oil with flakes of the clutch is gong around the entire tranny and will damge other things.
