I never saw any reply to my question on whether or not you checked the fluid in neutral or park. I quoted it above. Low fluid level will cause it to shudder taking off
Yes you are right. I didn't post an answer for you. Your question is a good one, and yes, I am checking the trans oil in neutral, on level ground, and warmed up. It is pretty wild how much the level will raise after setting a few days, then checking it before start up.
I haven't been to the car for a couple of days. Been a bit sick here. I am planning on getting there in the next couple of days to try tying the TPL back and seeing if I can feel a difference. Also want to take some pictures of the TPL setup so, with some help from you guys we can figure out what I need to make it right.
