Just noticed this. When I'm in 4-Low and I go from reverse to park, it makes a terrible sound. It's like a high pitched sound of gear teeth rubbing against each other. It's just for a fraction of a second and then it stops (catches)? It sounds like this: Bzzzt. /forums/images/graemlins/grin.gif It doesn't do it from 4-High, only Low. And another wierd thing is that it seems to take two cycles to do it: I hold my foot on the brake and go P-R-P-R-P, then the noise. Like the first time from R to P doesn't make the noise. I have no idea if it's in the T-case, or maybe the front axle. I've got the stock front 10-bolt with an Auburn. Everything seems to be working right, it's just a nasty little noise! /forums/images/graemlins/frown.gif Thanks for any ideas!
