Hi everyone,
I am wondering if anyone here has installed the Transgo shift improvement kit and/or the Sonnax line pressure booster in their newer Grand Cherokee? I have a 2011 overland hemi that has the 545rfe, the same trans that was in my 09 4.7 Grand Cherokee. I installed both the Transgo shift kit and the Sonnax line pressure booster in the 09 and was very pleased with the performance gains they had to offer, I later got the superchips tuner with the trans app and it was even better.
I am wondering if anyone has done the same mods to the WK2 platform and if so, how it turned out?
Zach
