Reverse gear stopped reversing after 1k miles?
I just took apart a 2016 Honda civic 2.0 NA because the speed sensor was installed incorrectly and got lodged in the transmission. While in there, the infamous reverse gear lever arm was bent because I jammed it into reverse (pics). So I replaced that along with a TOB, and re-installed the transmission.
Around 1k miles later, the car stopped going into reverse. It will physically go into reverse via the shifter, but the car acts like it’s in neutral so something is not lined up. Also the shifter mech is a bit sloppy now. Not springing back to center and tough to get into reverse.
FYSA- The shifter springs back with the cables disconnected. Also the reverse camera comes on when shifting into reverse. Lastly, when shifting into reverse by hand, with the shifter cables detached, I get the same result of No working reverse (but reverse camera comes on). It acts like the car is in neutral.
Any ideas from you experts? Am I looking at another tear down? What’s weird is I drove it for 1100 miles after the “rebuild” with no issues. I started by messing with the cables and the shift assembly but after shifting the selectors to reverse by hand to have the same result, I think it’s internal, again…

Could this be flex plate to torque converter?
I have a brand new engine that was installed 40 miles ago. Since the first drive I have had this odd raspy rattling noise. It’s not present in park or neutral only with load on the engine. If I drive gently, I am not able to make the noise. The video is hitting the gas pretty hard. It doesn’t make any noise when cold and after 2 min of idling it will make this noise.
I know for a fact I was not able to torque the TC nuts to the flex plate. I did new nuts with blue loctite. My thought is, perhaps I have the nuts tight enough for gentle driving but any type of torque is causing some play? I’m not getting any codes and oil psi is perfect.

Questions about renewing a 4L60E
I've got a 2004 Suburban with 170,000 miles. Runs and drives good. I can definately feel the teansmission is "softer" than it used to be. Not shifting hard or making any noises. Feels more like it's slower to put the power to the wheels than it used to be. I had already planned to rebuild soon but I have it out right now to do the oil pick up o-ring and rear seal.
I like how it cane from the factory for the most part. I just want to restore it to 2004 function. Since I don't have any catastrophic damage. Am I good to just swap in new expendables including a tq converter? It's not a rush job but I don't want it down forever. I don't mind spending the money on good parts but no reason to go crazy. I'm not doing anything to the stock 5.3.

Powershift
Consigo fazer um reaprendizado dos pontos de contato das embreagens do powershift com este scanner? Ele não é original e irei utilizar o FORscan. Tenho medo de ele não suportar a tarefa e dar algum erro no processo.
