Does it reverse in park? Sounds like the linkage is out of adjustment.

Yeah, I'd check the cable connected to your trans. If it looks okay, then disconnect it and see if you can manually set it into park. Having your trans fluid level way off can also cause that.

You say you found copper in your pan? There shouldn't be any copper parts on your trans - at least none that I can think of.

Actually the cable with the spring is the wrong one. That one just tells the transmission where the throttle position is. You want the main thick cable, although they both go to basically the same place. Either way both connectors just pop off. Pull on the very end piece (like a plastic square) directly upward. It just snaps back on. It will be hooked directly to one of two levers, which this will be the lower or bottom one.

Can't think of anything in the valve body or transmission gears that would be brass or copper, other than a couple connectors or maybe the vent tube. Lets see what works and what doesn't first, the we can figure what the metal chunks are. Check if each hear position works or not. This basically bypasses the shifter, to eliminate it as a problem.

There are thrust washers and bushings in the trans. When they wear enough to shed flakes it is a sign of major wear on the hard parts.

no shift forks in an auto.

The fact that it still goes into park and you can start it in park means the linkage is fine and you have internal mechanical failure.

Car-part.com to find salvage yards near you with the parts.

So let me make sure I understand the problem. You have no reverse when using your shifter inside, but it all works fine when you manually move the lever on the trans. Is that correct?

The transmission has one thrust washer, which comes in varying thickness and is used to set the end play spacing. It's very unlikely the metal is from that. The 42/44/46 RE transmissions are all hydraulically controlled. Reverse failure is usually the result of misadjusted or damaged linkage, but can also be from your park sprag sticking, or valve body failure, or rear servo failure, or burnt front clutch.

Beware of getting parts from salvage yards for transmissions. Sure they claim it's only got xxx miles on it and it works great guaranteed. You can pick one up for around $600 and you have about a 30% chance it will work, and can take it back for a refund if it doesn't. Of course that's only after spending 8-12 hours checking it. I went through 3 before I found one that worked, and it probably only worked because I rebuilt it. Swapping a trans is no small task. Lol

He hasn't taken the linkage off the lever yet.

Park is park
Reverse is nothing
Neutral is forward

Try starting the jeep with the lever in neutral.

Are you able to start it? I'm assuming yes, since neutral is drive, but do the other drive ranges (2, 1) work as they should? They only thing that will really change things so that your shifter is not what the transmission is really in, is the gearshift linkage cable. This is why I would say to check each position of the transmission by disconnecting the cable and run your Jeep in each position. This will take two people to do, as one person will need to have their foot on the brake, while the other changes to the next gear by manually moving the switch. There are like 10 possible causes covering a wide range of parts, and knowing what does and doesn't work will help eliminate like 7-8 of those

IT starts fine in park and neutral. i didnt manually run the jeep cause its just me workn on it by my lonesome. i changed the filter today and put new fluid in thinkng that would help and of course it did not. The trans is A 46 RH. when i droped the pan for the most part everything looked pretty decent in side it.
Starts in park. Starts in neutral. Drive, 1 and 2 all work fine. Overdrive works when engaged. Reverse feels like park neutral moves forward. I cant push the jeep back of forward when in neutral unless i disengage the transfer case. I hope this helps define the situation a bit more.
