Got the tranny out of my 92 351w to replace the torque converter. It shifts O.K but shudders and it will barely turn the rear tires under a power brake with pedal to the floor. Went to the shop that sells refurb converters to get a new one today and the guy says "You don't need a new converter, you need a solenoid pak and a shift kit, we see this all the time." But I'm wondering where my low end "take off power" went and what caused it to go. I've heard and read the actual TC causes this power loss and have a hard time believing a solenoid pak and shift kit is going to give it back. I guess I don't mind buying both cause I don't want to pull the tranny again until I have to. With the core the refurb TC is about $135.00. I've already spent $200.00 on the solenoid and kit. Any advice would be appreciated!!!!
