I just sandblasted my TCT the correct way and put it all back together exactly how it said too on the DIY. Now when I put my car in neutral if im rolling or have to do a quick 5 feet drive than stop the RPMS dip to like 200 and almost cuts off. Any ideas?

 

Did you disconnect the battery during the TCT process? If so, did you do the idle re-learn procedure?

 

I did not disconnect the battery, the TCT was out of the car for a day and a half I kept the opening covered so nothing went in or out of the hole.

 

Are you sure the TCT was put back together?

 

Funny...I had the same issue that you're describing.
Did you re-install that oil plug bolt? It goes on after you remove the bolt that you lodge in to compress the plunger. Reason I ask is because I was guilty of this. Finally figured out that I left out that oil plug bolt. And, the idle returned to normal after I installed the plug bolt. No damage, knock on wood.

 

Don't laugh too hard.... I forgot to plug in whatever sensor that is right above the TCT. I'm kind of slow..

 

Strange that the oil pressure switch would effect idle, thats the plug your referring too.
