2009 srt8 Jeep Grand Cherokee 426 stroker
Hello I’m new to the site and need help with figuring out what’s going on with my Jeep. It is stuck in limp mode it will not go over 3000 rpm,won’t shift into overdrive I manually shift it to keep up with traffic when I do drive it. The traction control light won’t go off. It has been an on going problem since I had it built. I had it at a shop and they had me buy a pcm an abs control module until they got tired and couldn’t figure it out then it went to the stealership and after $2500 more thrown at it. Crankshaft sensor and ati harmonic balancer reinstalled. Took it to another tuner who told me that he couldn’t tune it because of the crankshaft sensor falling out of system. $800 tow bill. Got it home and I put original pcm with an hp tune I was able to get cel light off but not traction control light. If you can help please let me know what else I can check any help is greatly appreciated. I love my Jeep but I’m almost ready to sell it.
