My daughters 05 rubicon 4.0 Auto transmission. When the tpms get up to 3250 it starts jumping around like it’s hitting rev limiter. I’ve delt with this problem before at 2500 rpms on another 05 but it threw codes. Ive replaced the OPDA, cam sensor and ECM in this keep fixing the transmission none shift problem in the ECM but now it’s doing this and not throwing any codes. Any help with this would be great. If cam gear is worn what does that look like so I will know? I about ready to rip this crap out and go to a 01 engine and trans and be done with this 03-06 bull crap!
