On my 76 F150 with a 300 and c4 it has a leak where " correct me if in wrong" the adjustment screws are for the bands. There are 2 one on each side with a square head it looks like its leaking around the threads. Can I just unscrew them and rap Teflon tape around them or will it mess the adjustment up? And the is a small leak around where the shifter goes in and the kick down how do u fix this leak??
