42re transmission problems.

I'm back with yet again more questions. It seems that my transmission is really starting to go. When I go from asphalt to dirt a give it gas a weird noise come out of the center console area. Or if I'm driving on a dirt road and I'm in a rut (mud season up here in Vt) and punch on it I hear a grinding type noise. I'm not sure if it's coming from the transmission but that's my only guess so far. I need any help I can get. Thank you!

You sure it's not your transfer case? Stretched chain in the t-case will cause that.

You'd have to pop open the t case to confirm. There should be little slack. If it's loose, you need a new chain.

What did you have to replace? Should I just buy a new one or just fix the old?

Again I replaced the chain, it's like 70 bucks. By fixing the old one you mean removing a link or two? The chain is an inch thick, good luck.

Well it's somewhat a pain in the butt. The Jeep was down for over a week, mainly because I had to order the parts and I decided to change the mode/range fork pads while I was at it. Also I broke a snap ring in the process (that one was really a pain). I wasn't in a rush cause it's my play vehicle. It was a little tricky to put the new chain in, I'm not too sure how I managed to shove it in there. Some folks just pull out the whole assembly, I decided to leave it in there.

I mean it's doable, watch some youtube videos and make sure you know where everything goes back. There are lots of little pieces that can come loose.

Alright thanks, this is sadly my main rig so its gonna have to be a quick swap haha. I'll probably just pull the whole case and try to just swap the chain out.

I think First you want to determine if its the xfer case or the tranny. Each one of those are expensive and time consuming to fix. It would be a sin to fix the wrong one and still have the problem! If it has selectrac (a 242) I think (feel free to jump in here anyone) if you shift it into rear wheel drive mode only the INPUT half of the transfer case is spinning. See if the noise goes away when you do this.

I think that cover on the end comes off fairly easily and you can look at the chain.
