NP207 transfer case possible loose chain

What are the symptoms of a loose transfer case chain? I've got a single hard bump when I get on the throttle. It will do it if you pull out really quickly and sometimes when your flooring it and it shifts to 2nd. Oh by the way mine is a 700r4 in an 85 Jimmy. I've checked for broken trans mount, loose ujoints, Slip yoke play. Thanks

The chain isn't used unless you are in 4wd, so that probably isn't your problem.

Re: NP207 transfer case possible loose chain

Yep, both trans and t/case fluid levels are fine. I just realized I have a problem with the t/case shifter. This may or may not be related to my thumping sound. I put it into 4-lo for the first time and the stick won't engage all the way. I'm not sure if the t/case shifter hitting the tunnel. The v8 engine is set back 1" for better radiator clearence. I'll check it out later this week. Thanks
