Procal module problem need help
Just got 4.56 gears installed. Used procal module double checked all the switches to adjust for new gear ratio. Got the 2 horn honks. Drove home about 15 miles. Check eng light came. It will nit shift above 3rd gear 60 mph turning 4600rpm. Will not let me shift manually (i have the auto trans). At one point would not let me go over 25mph. Was able to pull shut off and then could drive again. Trans not engaging as it should from a stop light. Please help with some advice

Are there any codes? Was a locker installed? Taller tires? Is the correct (measured) height programmed in? Speed sensors? (I am not up to speed on those, but have seen previous posts where they were the issue)
Did you drive it before programming with the procal? If so, same issues?

try disconnecting the battery then if if still is giving you problems try wiping the settings and going back to factory settings and do a test drive and see what happens.
