Trouble code is for the tcc pwm solenoid. ....went threw my transmission pan to replace and learned that there is a tcc apply and the tcc pwm.....the tcc pwm is my trouble code but the weird part is my tranny didnt have one nore did it have a spot for one????(guessing not the original transmission) car just recently started "bucking" under acceleration. Would the missing tcc pwm selenoid cause driving issues and if so how do I fix this with no spot for one in my tranny???
