This YouTuber had an issue with losing power while driving and a pesky check engine light. This was solved with a WranglerFix PCM.
The PCM in this 2006 Jeep Wrangler TJ with automatic transmission is replaced with a Wrangler Fix unit. In a previous video the issue was discussed and the PCM was determined to be defective. Follow along in this video as Ozzstar replaces the OEM unit with an aftermarket PCM and takes the Jeep on a test drive with some commentary and thoughts.
