The past 28 years of being involved with ATSG’s technical help line has been a continuous learning experience. Particularly when a problem is resolved outside the parameters of what would normally fix the problem.
For example; several years back Lorenzo Ortiz from Phillips transmission had a 2003 Jeep Grand Cherokee 4.0L 4x4 with a 42RE come into the shop for transmission repair. After installing a rebuilt transmission, the vehicle exhibits a misfire. This was not a problem before transmission repairs. Upon inspection, the vehicle has stored a P0352 code for an ignition coil #2 primary circuit fault.
