I have a 95 lightning with ford motorsport scharger, high flow cat pipe with 2.5" dual exhaust. Full throttle starts, it doesn't want to upshift unless I let off of the throttle. I'm thinking about new solenoid pack and ftvb. The boys @ chickenears recommended I contact you first & get your opinion. If you recomend ftvb, am I looking for an F4 for my truck, and is there a larger trans pan available for 95 E4OD. Any advice would be appreciated.
