Thanks ordering valve body in morninghere we go again. call all the tuners and discuss your needs and plans. Go with the one you feel most comfortable with. You will want a JW or BTS valve body first. Tell your tuner you have it and that will help them to tune the trans. Good luck.
Thanks for advice if it blows, just have to fix it dont have time to play blame game $$If its reving high then shifting it sounds like you have a trans issue, so before getting a chip and then ruining your trans and blaming it on the chip......I would address the trans issue first.
Although a chip will help in so many ways,the first thing to address is why now after installing 37's is the trans is "acting" up. Didn't happen before, right?Have a 2001CCSB 7.3 just put 37's on it tranny revs high and then shifts who has best chip for shifting rpms and lock up with big tires. Thanks
