Hey Scotty. Ive got a 2008 Jeep Wrangler with the 3.8 liter engine, automatic, it now has about 220k miles. No crazy modifications, just 33 inch road tires. The transmission was rebuilt about 3 years ago (22k miles ago) by Aamco by a previous owner. He gave me the paperwork but the warranty expired a while ago. Ive owned it for 2 years. I am now getting a shuttering noise and feeling when the jeep reaches between 12 and 1400 rpm between 45 and 54 mph. It drives and sounds fine at lower speeds and higher speeds as long as Im not in that 12 to 1400 rpm range. Do you think that would that be differential or transmission related? Thanks bud your the best out there!
Please don't double post.
No I know it's generally the transmission but if you can find a mechanic like me in your area and have them put his vibration sensors all over the car and then analyze it with an oscilloscope you can find the source of the vibrations very quickly
Thanks Scotty, what I figured.
