I'm pretty sure I've narrowed my transmission problems down to my torque converter. If I hit the gas hard from a stop, the car will shudder. TC shudder. Going up hills, the car shudders. When you take your foot off the brake and you're in drive, the car BARELY moves under it's own power. My mom's L36 feels stronger off the line and moves a lot easier. If you let off the brake, it takes off pretty well on it's own, unlike mine.
I can get a torque converter for $120, and if this is the problem, I'd much rather just go ahead and change that rather than trying to source an entire tranny.
So, does this sound like TC problem to you guys?
