47RE

Tranny jerking from 4 into OD.

Feels like Engine is cutting out.

47RE is only a 4 Speed transmission. 4th gear and OD are the same gear. You might be thinking the torque converter lockup?

our trucks can be funny beasts; loose battery terminals (even if not very loose) can cause this. Mine were tight and the problem you described was slowly coming back, so this weekend I put new battery cables on and the problem is mostly mitigated, again. It still could be a little smoother, I think. I have a stock stall converter showing up soon, so next thing is swap out the converter since that was on the agenda anyway.

This is something I got a member for the other day. Most people don't get the terminals down all the way. The barely grab the top of the battery posts and tighten down terminal. I typically loosen the clamp bolt wide then using a socket and rubber hammer smack the battery terminal down on the battery post fully then snug up the terminal clamp bolt. I know this is not the recommended method of doing this. 

 

I just need to buy a pair of terminal spreaders...

Thanks for the good advice. I'll be sure to do that soon enough.
