I have to replace my 2007 Jeep Commander Sport 4.7 FLEX engine, Will the upgraded 2008 Powertech 4.7 fit w/o any issues?


Asked by Sep 22, 2016 at 11:55 PM about the 2007 Jeep Commander Sport 4X4

Question type: Maintenance & Repair

My 2007 Jeep Commander Sport, 4.7 FLEX has succumbed to the dropping Valve seat issue at only 120k - I would like to drop in the upgraded 2008 4.7 PowerTech in, since they quietly resolved the problems with the 1st gen 4.7 and pulled 70 more HP, and more Torque, while improving MPG.
I can't seem to get any accurate concrete info on this, but it appears they didn't change the transmission, or anything other than the internal design. I hope the bolt patterns mount to the trans is the same, and the motor mounts, as well as the transmission - It seems like they may have had to improve the trans, or torque converter due to additional HP?? If anyone can give me a resource to   check, or a contact to get additional details - it would be greatly appreciated. Thank you.
