Personally I would never use an engine flush product, but instead just do very short (200-300 mi) OCIs with synthetic (which has additives designed to trap and isolate the nasty stuff that shouldn't be running around inside the engine). You need to do this until the drained oil looks clean. Can't tell you engine flush products aren't good - I just go by the fact that most automakers I'm familiar with say to use no oil additives, and I don't like the idea of putting anything in there except quality engine oil.
I think you'll need to breathe, and start over with as few variables as possible. You're trying to makes sense of a lot of things and make one problem tie it all together.Can a bad wire cause it to act up more when warn though? The longer i drive it the worse it gets.
So, rolling in neutral, you shut off the engine carefully, and the 'shuddering' continued... you have something binding up in the rolling chassis.It still does it with the engine off.
It's an old van. You may have some worn out bushings on the lower control arms and definitely check your motor mounts and tranny mount. My mounts went bad it stopped my shaking problem. I bought them from a place on the east coastI have an 03 t&c with only 64K & im the 2nd owner. For 3mo ive had an issue i cant figure out. At 30-45 mph it shudders & shifts a little hard at time and kinda feels like a bad torque converter & idles low & rough at stop lights. The fluid is pink & clean. The cel is not on but had it scanned anyway & nothing. Now it jerks at all speeds & im at my wits end. Please help. Thanks
I use full synthetic.Think you have it wrong here.
Oils high in detergents, keep the "nasty stuff" running around inside the engine, then that "nasty stuff" would be drained out along with the oil on your next oil change, while that "nasty stuff" settles down in the oil pan (and other engine parts such as heads) if oil low in detergents is used, in this case, such "nasty stuff" would not be drained out in your next oil change.
It's not just for slip, that was just part of the front label I read, it helps with hard shifting too, helps with worn parts and adds lubrication. Made a world of difference to my 2000 F150 that was starting to have hard shifts and some shuddering and I was scared to do a flush at that point, but every vehicle is different.The trans isnt slipping.

It's simply called Lucas Transmission Fix
