I'd go with the torque converter and shift kit for sure.

 

Yeah I thought I did so I got it checked out. Turns out the guy said the trans looks good. I asked why was I having problems. He said the "sub par" torque converter. I looked it up

Turns out our torque converters have a 65% efficiency rate....that SUCKS...

but thanks for the opinions I'm pretty sure I'm gonna go with the TC and shift kit
