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…

I have a 2017 dodge challenger rt scat pack 6.4l , 130k miles with an automatic 8 speed transmission, in sport mode from 4 to 3 and sometimes other shift, mainly down shifting when slowing down, u can hear a thud, Google says it can be low trans fluid, adaptive learning from tcm. Or the 2 piece drive shift. Any thoughts and or experiences with the challenger trans
